конструкция и составляющие, порядок монтажа ливневки с кровли

Без присутствия системы водоотвода на здании осадки могут повредить стены и фундамент. Ливневка на крыше отводит дождевые и талые воды от дома, защищая строение от разрушения. Установить систему можно самостоятельно, но важно учитывать все нюансы монтажа.

Ливневка на крыше отводит дождевые и талые воды от дома, защищая строение от разрушения.

Конструкция водоотвода

По способу организации водоотвод с крыши бывает неорганизованным и организованным. В первом случае не устанавливаются никакие ливневые системы, а жидкость с крыши падает непосредственно вниз.При этом она попадает на фундамент и стены, ускоряя деструктивные процессы в них. Организованный предусматривает закрепление ливневой конструкции на крыше, что позволяет отводить воду дальше от сооружения.

По способу монтажа система бывает наружной и внутренней. Первый тип монтируется под свесами кровельного материала и подходит для скатных крыш. Для изготовления такой конструкции применяется металл или пластик. Внутренний водосток обустраивается в домах с плоской крышей.

Он проходит в стене. При этом крыша делается под небольшим уклоном, в самой нижней части которого присутствует водоприемная воронка. Чаще всего такая система водоотведения с кровли монтируется в многоэтажных зданиях.

Составляющие элементы водоотлива для крыши

Ливневая система состоит из таких элементов:

1. Желоб. Это главная часть конструкции, которая фиксируется непосредственно под скатом кровельного материала и принимает потоки воды. Устанавливается он по периметру сооружения под небольшим уклоном.
2. Воронка. С ее помощью вода направляется в сливную трубу. Для предупреждения попадания крупного мусора или листьев воронку в верхней ее части лучше оснастить защитной сеткой.
3. Элементы для слива жидкости в канализацию.
4. Внутренние и внешние углы.Применяются в сложной конструкции.
5. Муфты. Они служат для соединения желобов, если конструкция длинная.
6. Колено. Элемент устанавливается в нижней части слива и отводит жидкость дальше от сооружения.
7. Кронштейны и хомуты. Это соединительные элементы для труб и фиксации желобов.
8. Заглушка. Она устанавливается для ограничения потока воды.

Муфты служат для соединения желобов, если конструкция длинная.

Приобрести можно как стандартную систему, так и заказать изготовление индивидуального проекта.

Как правильно рассчитать число труб для водостока?

Чтобы конструкция работала правильно, необходимо сделать расчет необходимое количество ее элементов. Площадь их сечения должна быть достаточно для того, что воды без остановок и переливов через края желоба проходила даже в самые сильные дожди.

При выборе конструктивных элементов нужно учитывать площадь крыши, сечение труб, климатические условия эксплуатации ливневки. Стандартным является такое значение: 1 кв.см. площади сечения перекрывает 1 кв.м. площади кровли. Для небольших домов потребуется сливной фрагмент диаметром 50-75 мм. Для крупных сооружений это значение увеличивается до 160 мм.

Что касается воронки, то на 1 м.кв. горизонтальной площади крыши приходится1,5 см.кв. ее сечения. Расчет внутренних и внешних соединительных углов производится исходя из конструкции системы водоотвода.

Желоб как один из главных и важных компонентов устройства

Один из основных элементов конструкции, который принимает воду с крыши. Существует несколько его разновидностей: настенный или подвесной. Для изготовления используется пластик, оцинкованный металл или медь.

Настенный

Он локализуется близко к свесу кровельного материала на самом краю крыши. Изделие представляет собой бортик, высотой до 20 см и выполняет функцию барьера для дождевой воды. Устанавливаются такие желоба под углом к свесу и направляются к сливной воронке. Для соединения лотков применяется клей или двойной лежачий фланец. Угол их наклона составляет 15 градусов, что предотвращает перелив жидкости через край.

Дождевой или подвесной

Он плотно крепится непосредственно под кровельным свесом, что не дает возможности набравшейся жидкости затекать под желоб. Для фиксации применяются стальные крючки, по форме соответствующие изделию. Так как данный фрагмент не перегибается, то во избежание его переполнения в нем нужно сделать отверстие в заранее отмеченном месте. При расчете уклона в этом случае учитывается количество осадков, выпавших за год.

Классификация желобов

По форме выделяются такие виды желобов:

Разновидность	Характеристика
Полуэллиптический	Хорошо справляется с большими потоками воды, так как обеспечивает большую пропускную способность
Полукруглый	Он устойчив к нагрузкам, имеет высокий уровень жесткости. Такой желоб универсальный, так как применяется на большинстве кровельных конструкций

Еще желоба классифицируются по материалу изготовления:

1. Пластиковые.Они имеют привлекательный внешний вид, небольшой вес и невысокую стоимость. При правильном креплении и применении срок из эксплуатации составляет 15-25 лет. Смонтировать их можно самостоятельно. Крепятся такие фрагменты при помощи муфт или защелок с резиновыми уплотнителями. Иногда для фиксации применяется клей. Но такие изделия имеют высокий риск механического повреждения, делаются хрупкими при отрицательной температуре. Небольшие царапины на поверхности можно замаскировать акриловой краской.
2. Алюминиевые. Для соединения используются крепления с резиновыми и силиконовыми уплотнителями или специализированный клей. Необработанный материал может быстро покрыться ржавчиной. Избежать этого поможет слой лака.
3. Оцинкованные. Представляют собой металлические изделия с предварительно нанесенной полимерной защитой. Характеризуются широкой цветовой гаммой. Для крепления используются скобы с защелками, оснащенными резиновыми уплотнителями. Такие желоба имеют высокую прочность и не поддаются коррозии, если только не поврежден полимерный слой. Недостатком является частое отсутствие правильной формы, что усложняет сборку системы.

Еще в магазинах можно приобрести изделия из меди. Они прочные, устойчивые к ржавлению, имеют привлекательный внешний вид и продолжительный срок эксплуатации, но у них высокая стоимость.

Ливневка из меди прочная, устойчивая к коррозии, имеет привлекательный внешний вид и продолжительный срок эксплуатации, но у неё высокая стоимость.

Как правильно рассчитать желобы?

Стандартная длина элемента составляет 3-4 м. Для маленьких зданий хватит изделий сечением 70-115 мм. На больших сооружениях устанавливают желоба сечением до 200 мм. Нужно рассчитывать указанный фрагмент так, чтобы расстояние между ближайшими воронками составляло 8-12 м.

Собираем конструкцию желоба

Если длина желоба больше 12 м, то требуется несколько фрагментов, соединенных между собой крепежных элементов. После этого на краях конструкции устанавливаются заглушки и она фиксируется на кронштейнах.

Основные этапы монтажа системы водоотвода

Оборудование дачного дома ливневой системой можно осуществить самостоятельно. Для этого нужно произвести такие действия:

• установить кронштейны;
• смонтировать и закрепить желоба;
• зафиксировать сточные трубы и их держатели;
• обустроить отвод лишней жидкости в заранее выбранное место.

Проверка всех соединений проводится на каждом этапе выполнения работ.

Монтаж кронштейнов для слива

Для закрепления кронштейнов нужно соблюдать расстояние между желобом и стеной, которое колеблется в пределах 60-80 мм. В этом случае не образуется конденсат. Установку элементов делают с соблюдением уклона системы. Он составляет 5 мм на каждый погонный метр длины конструкции.

Сначала делается разметка кронштейнов. При длине кровельного ската около 6 метров перепад высоты в двух точках – первой и последней – составляет 60 см. От края крыши до крепежного элемента должен соблюдаться промежуток – 100-150 мм. Шаг между соседними кронштейнами колеблется в пределах 50-60 см для металлических конструкций и 30-40 см для пластиковых.

Сначала фиксируется первый верхний элемент, который находится на противоположной стороне от водосточной трубы. Следующим прикручивается последний, самый нижний кронштейн, после чего между крепежами натягивается бечевка и производится разметка остальных фрагментов. Для монтажа применяются стандартные саморезы.

Воронку нужно устанавливать на расстоянии 30-60 см от края желоба, причем фиксация производится за 15 см от нее.

Монтаж сточных желобов

Их нужно только собрать и зафиксировать на кронштейнах. Способ крепления зависит от типа системы и материала ее изготовления.

Установка сточных труб и держателей

Это последний этап сборки конструкции, на котором трубы для отвода воды устанавливаются строго под отверстием ливневой воронки. Для их фиксации используются хомуты, которые при помощи дюбелей прикручиваются к стене на расстоянии до 200 см друг от друга.

В последнюю очередь монтируется сливное колено, отводящее жидкость подальше от дома.

Куда отводятся дождевые воды с кровли дома?

После того как система будет установлена, нужно организовать место, где будет собираться дождевая вода. Тут возможны несколько вариантов:

1. Емкость. В землю на расстоянии 0,5-1 м от здания вкапывается бочка, к которой направляется сливное колено. Ее можно устанавливать и на поверхности грунта. Собранная жидкость используется для полива домашних или огородных растений.
2. Фильтрационный колодец. Она представляет собой яму, дно которой устилается щебнем. После этого монтируется колодец из бетонных колец.
3. Канализация. Тут нужно предварительно получить разрешение соответствующих коммунальных служб.
4. Дренаж или водоем.

Фильтрационный колодец представляет собой яму, дно которой устилается щебнем.

Ливневка – обязательная конструкция, позволяющая защитить фундамент дома и его стены от разрушающего действия дождей, талой воды.

90000 Rainwater Collection | Private Water Systems | Drinking Water | Healthy Water 90001 90002 90003 90004 90002 Collecting and using rainwater can be a great way to conserve resources 90006 1 90007. Some people use rainwater for watering plants, cleaning, bathing, or drinking. Rainwater collection is not allowed in all places. Some statesExternal consider rainwater the property of the state and prohibit its collection, so you should consult with your local government (for example, your environmental quality department or health department) before proceeding 90006 2 90007.90004 90011 Germs and Other Contaminants 90012 90002 While useful for many things, rainwater is not as pure as you might think, so you can not assume it’s safe to drink. Rain can wash different types of contaminants into the water you collect (for example, bird poop on your roof could end up in your water barrel or tank). Rainwater can carry bacteria, parasites, viruses, and chemicals that could make you sick, and it has been linked to disease outbreaks 90006 3-4 90007. 90004 90002 The risk of getting sick from rainwater may be different depending on your location, how frequently it rains, the season 90006 5 90007, and how you collect and store the rainwater.Dust, smoke, and soot from the air can be dissolved in rainwater before it lands on your roof. Roofing materials, gutters, piping, and storage materials can introduce harmful chemicals like asbestos, lead, and copper to the water, though building standards minimize some of this 90006 6-8 90007. Dirt and germs can be washed into collected rainwater from the roof, especially when rain follows several days of dry weather 90006 3-4, 90007 90006 9 90007. 90004 90002 90028 90004 90002 Rain barrels, for example, do not provide any type of disinfection or filtration.Adding chlorine or iodine to water does not protect against chemicals, and some parasites are very chlorine tolerant. Boiling the water will kill germs but will not remove chemicals. Using a simple device called a «first flush diverter» to remove the first water that comes out of the system (which may have been sitting) may help avoid some of these contaminants 90006 8, 90007 90006 10 90007. 90004 90002 Some cisterns, which are common in certain areas, can provide safe water supplies. Some people add purchased, treated water to the rainwater they collect in their cistern.This may make the treated water less safe. Cisterns that are intended for drinking water should be properly maintained 90006 8, 90007 90006 11 90007. Consider adding a screen to the water inlet or emptying the rain barrel in less than 10 days to prevent mosquitoes from using the rain barrel as a breeding site 90006 9, 90007. Water intended for drinking needs to be filtered, disinfected, and tested regularly 90006 9, 90007 90006 12 90007. 90004 90011 Preventing Illness 90012 90002 If you collect and store rainwater for drinking, you have a private, or individual, water system and are responsible for ensuring that your water is safe.You should have your water and your system tested regularly and maintain the system properly 90006 4-5 90007. When rainwater is used as a supplemental water source, homeowners should ensure that rainwater can not enter pipes containing safe drinking water 90006 4, 90007 90006 6 90007. Contact your state or local health department for more information. 90004 90002 To lower your risk of getting sick, consider using rainwater only for uses such as watering plants that you do not eat, washing items that are not used for cooking or eating, and bathing (keeping water out of your mouth and nose).If possible, avoid using rainwater for drinking, cooking, brushing your teeth, or rinsing or watering plants that you intend to eat. Instead, use municipal tap water if it is available, or purchase bottled or bulk water for these purposes. 90004 90002 If you have a weakened immune system, you should be especially careful when choosing your drinking water source. Discuss this with your healthcare provider. 90004 .90000 How Can It Help Your Health? 90001 90002 Drinking hot water can provide your body with the water it needs to replenish fluids. It can also improve digestion, relieve congestion, and even make you feel more relaxed. 90003 90002 Most people who drink hot water as a holistic health remedy do so first thing in the morning or right before bed for optimal health benefit. 90003 90002 Warm water to a temperature between 120 ° F and 140 ° F. Hot water should not be hot enough to scald your taste buds (temperatures of 160 ° F or more can scald and result in significant burns).90003 90002 Add a twist of lemon for a vitamin C boost, and you’re already on your way to better health. 90003 90002 Here are 10 ways that drinking hot water may benefit you. 90003 90002 The warmth of hot water creates steam. Taking a deep inhale of this gentle vapor while holding a cup of hot water can help loosen clogged sinuses and even relieve a sinus headache. 90003 90002 Since you have mucous membranes throughout your neck and upper torso, drinking hot water can help warm that area and soothe a sore throat caused by mucous buildup.90003 90002 Drinking hot water both soothes and activates your digestive tract. Water is, after all, the lubricant that keeps your digestion going. As the water moves through your stomach and intestines, digestive organs are better hydrated and able to eliminate waste. 90003 90002 Hot water can also dissolve and dissipate things you’ve eaten that your body might have had trouble digesting. 90003 90002 Drinking hot water can calm your central nervous system and lubricate your body. When your nervous system is primed for healthy and controlled reactions, you’ll find that you feel fewer aches and pains, as well as less panicked throughout your day.90003 90002 A person who has arthritis might get an extra benefit from using hot water — to calm their central nervous system. 90003 90002 Drinking hot water helps your intestines to contract. When that happens, old waste trapped in your intestines is able to pass out of your body. Drinking hot water regularly helps keep you, well, regular. But drinking it occasionally when you’re constipated is not a bad idea, either. 90003 90002 Hot water is no different than room temperature or cool water when it comes to keeping you hydrated.90003 90002 A common recommendation from health authorities is that an adult should drink eight 8-ounce glasses (about 2 liters or a half gallon) of water a day. That’s a hard target for many people to hit. 90003 90002 Starting your day with a serving of hot water and ending your day with another will get you that much closer to being adequately hydrated. Your body needs water to perform basically every essential function, so the value of that can not be overstated. 90003 90002 Drinking hot water wakes your body’s temperature control system up.As your body compensates for the warm temperature of the water, it brings your internal temperature down, and activates your metabolism. 90003 90002 Hot water also helps your intestines contract to clear out waste products that are bloating your body, which gets rid of the dreaded «water weight.» 90003 90002 Taking a warm bath helps your circulatory organs — your arteries and veins — to expand and carry blood more effectively throughout your body. Drinking hot water can have a similar effect. 90003 90002 Healthy blood flow affects everything from your blood pressure to your risk of cardiovascular disease.As a bonus, warmth from drinking hot water or bathing at nighttime can help relax you and prepare you for restful sleep. 90003 90002 Since drinking hot water helps improve central nervous system functions, you might end up feeling less anxious if you drink it. If you add some warm milk to the mix, you might find that you’re feeling even more calm than after drinking hot water, according to one study. 90003 90002 Drinking hot water temporarily begins to raise your internal body temperature. When you drink hot water, or when you take a warm bath, your body’s endocrine system activates and you start to sweat.90003 90002 And while sweating might be uncomfortable, it’s an essential part of getting rid of toxins and irritants that you’re exposed to in your environment. 90003 90002 Achalasia is a condition during which your esophagus has trouble moving food down into your stomach. 90003 90002 People with achalasia (and with eosinophilic esophagitis) have trouble swallowing and also sometimes feel like foods get «stuck» (dysphagia) in their esophagus instead of moving to the stomach. 90003 90002 Researchers are not sure why, but warm water can help people with achalasia to digest more comfortably.Drinking warm water with oily food or a meat-heavy meal might be especially helpful for people with this diagnosis. 90003 90002 Drinking hot water has plenty of benefits, but it is not a magical cure-all. And drinking water that’s 90053 too 90054 hot can actually damage the tissue in your esophagus, burn your taste buds, and scald your tongue. Be very careful when you drink hot water — pay attention to the temperature. 90003 90002 You should not drink hot water if you’re working in a hot climate or exercising.Research shows that drinking hot water makes you less thirsty. If you’re environment or activity raises your risk of being dehydrated, give yourself the best chance you can to stay hydrated by 90053 s 90054 drinking hot water. 90003 90002 Getting into the habit of drinking hot water does not take a lot of work. Starting your day with water that’s been boiled and left to cool is an easy way to switch out your morning coffee. 90003 90002 Add a light session of stretching to your routine, and you’ll feel more energized and better equipped to tackle your day.90003 90002 If the taste of warm water does not appeal to you, add a twist of citrus — like lemon or lime — to the beverage before you drink it. 90003 90002 Drinking warm water before bed is a great way to wind down after a busy day. Knowing about the health benefits will have you sleeping soundly. 90003.90000 15 benefits of drinking water and other water facts 90001 90002 Keeping hydrated is crucial for health and well-being, but many people do not consume enough fluids each day. 90003 90002 Around 60 percent of the body is made up of water, and around 71 percent of the planet’s surface is covered by water. 90003 90002 Perhaps it is the ubiquitous nature of water that means drinking enough each day is not at the top of many people’s lists of priorities. 90003 90008 Fast facts on drinking water 90009 90010 90011 Adult humans are 60 percent water, and our blood is 90 percent water.90012 90011 There is no universally agreed quantity of water that must be consumed daily. 90012 90011 Water is essential for the kidneys and other bodily functions. 90012 90011 When dehydrated, the skin can become more vulnerable to skin disorders and wrinkling. 90012 90011 Drinking water instead of soda can help with weight loss. 90012 90021 Share on PinterestPossible benefits of drinking water range from keeping the kidneys healthy to losing weight. 90002 To function properly, all the cells and organs of the body need water.90003 90002 Here are some reasons our body needs water: 90003 90002 90027 1. It lubricates the joints 90028 90003 90002 Cartilage, found in joints and the disks of the spine, contains around 80 percent water. Long-term dehydration can reduce the joints ‘shock-absorbing ability, leading to joint pain. 90003 90002 90027 2. It forms saliva and mucus 90028 90003 90002 Saliva helps us digest our food and keeps the mouth, nose, and eyes moist. This prevents friction and damage. Drinking water also keeps the mouth clean.Consumed instead of sweetened beverages, it can also reduce tooth decay. 90003 90002 90027 3. 90028 90027 It delivers oxygen throughout the body 90028 90003 90002 Blood is more than 90 percent water, and blood carries oxygen to different parts of the body. 90003 90002 90027 4. It boosts skin health and beauty 90028 90003 90002 With dehydration, the skin can become more vulnerable to skin disorders and premature wrinkling. 90003 90002 90027 5. It cushions the brain, spinal cord, and other sensitive tissues 90028 90003 90002 Dehydration can affect brain structure and function.It is also involved in the production of hormones and neurotransmitters. Prolonged dehydration can lead to problems with thinking and reasoning. 90003 90002 90027 6. It regulates body temperature 90028 90003 90002 Water that is stored in the middle layers of the skin comes to the skin’s surface as sweat when the body heats up. As it evaporates, it cools the body. In sport. 90003 90002 Some scientists have suggested that when there is too little water in the body, heat storage increases and the individual is less able to tolerate heat strain.90003 90002 Having a lot of water in the body may reduce physical strain if heat stress occurs during exercise. However, more research is needed into these effects. 90003 90002 90027 7, The digestive system depends on it 90028 90003 90002 The bowel needs water to work properly. Dehydration can lead to digestive problems, constipation, and an overly acidic stomach. This increases the risk of heartburn and stomach ulcers. 90003 90002 90027 8. It flushes body waste 90028 90003 90002 Water is needed in the processes of sweating and removal of urine and feces.90003 90002 90027 9. It helps maintain blood pressure 90028 90003 90002 A lack of water can cause blood to become thicker, increasing blood pressure. 90003 90002 90027 10. The airways need it 90028 90003 90002 When dehydrated, airways are restricted by the body in an effort to minimize water loss. This can make asthma and allergies worse. 90003 90002 90027 11. It makes minerals and nutrients accessible 90028 90003 90002 These dissolve in water, which makes it possible for them to reach different parts of the body.90003 90002 90027 12. It prevents kidney damage 90028 90003 90002 The kidneys regulate fluid in the body. Insufficient water can lead to kidney stones and other problems. 90003 90002 90027 13. It boosts performance during exercise 90028 90003 90002 Some scientists have proposed that consuming more water might enhance performance during strenuous activity. 90003 90002 More research is needed to confirm this, but one review found that dehydration reduces performance in activities lasting longer than 30 minutes.90003 90002 90027 14. Weight loss 90028 90003 90002 Water may also help with weight loss, if it is consumed instead of sweetened juices and sodas. «Preloading» with water before meals can help prevent overeating by creating a sense of fullness. 90003 90002 90027 15. It reduces the chance of a hangover 90028 90003 90002 When partying, unsweetened soda water with ice and lemon alternated with alcoholic drinks can help prevent overconsumption of alcohol. 90003 90002 Water helps dissolve minerals and nutrients, making them more accessible to the body.It also helps remove waste products. 90003 90002 These two functions make water vital to the kidneys. 90003 90002 Every day, the kidneys filter around 120-150 quarts of fluid. 90003 90002 Of these, approximately 1-2 quarts are removed from the body in the form of urine, and the rest is recovered by the bloodstream. 90003 90002 Water is essential for the kidneys to function. 90003 90002 If the kidneys do not function properly, waste products and excess fluid can build up inside the body. 90003 90002 Untreated, chronic kidney disease can lead to kidney failure.The organs stop working, and either dialysis or kidney transplantation is required. 90003 90002 Urinary tract infections (UTIs) are the second most common type of infection in the body. They account for around 8.1 million visits to health care providers in the U.S. every year. 90003 90002 If infections spread to the upper urinary tract, including the kidneys, permanent damage can result. Sudden, or acute, kidney infections can be life-threatening, particularly if septicemia occurs. 90003 90002 Drinking plenty of water is a simple way to reduce the risk of developing a UTI and to help treat an existing UTI.90003 90002 Kidney stones interfere with how the kidneys work. When present, can complicate UTIs. These complicated UTIs tend to require longer periods of antibiotics to treat them, typically lasting 7 to 14 days. 90003 90002 The leading cause of kidney stones is a lack of water. People who report them often do not drink the recommended daily amount of water. Kidney stones may also increase the risk of chronic kidney disease. 90003 90002 In November 2014 року, the American College of Physicians issued new guidelines for people who have previously developed kidney stones.The guidelines state that increasing fluid intake to enable 2 liters of urination a day could decrease the risk of stone recurrence by at least half with no side effects. 90003 90002 Dehydration happens if we use and lose more water than the body takes in. It can lead to an imbalance in the body’s electrolytes. Electrolytes, such as potassium, phosphate, and sodium, help carry electrical signals between cells. The kidneys keep the levels of electrolytes in the body stable when they function properly.90003 90002 When the kidneys are unable to maintain a balance in the levels of electrolytes, these electrical signals become mixed up. This can lead to seizures, involving involuntary muscle movements and loss of consciousness. 90003 90002 In severe cases, dehydration can lead to kidney failure, which can be life-threatening. Possible complications of chronic kidney failure include anemia, damage to the central nervous system, heart failure, and a compromised immune system. 90003 90002 Some of the water required by the body is obtained through foods with a high water content, such as soups, tomatoes, oranges, but most come through drinking water and other beverages.90003 90002 During everyday functioning, water is lost by the body, and this needs to be replaced. We notice that we lose water through activities such as sweating and urination, but water is lost even when breathing. 90003 90002 Drinking water, whether from the tap or a bottle, is the best source of fluid for the body. 90003 90002 Milk and juices are also good sources of fluid, but beverages containing alcohol and caffeine, such as soft drinks, coffee, and beer, are not ideal because they often contain empty calories.Drinking water instead of soda can help with weight loss. 90003 90002 It was previously thought that caffeinated beverages had diuretic properties, meaning that they cause the body to release water. However, studies show that fluid loss because of caffeinated drinks is minimal. 90003 90002 The amount of water needed each day varies from person to person, depending on how active they are, how much they sweat, and so on. 90003 90002 There is no fixed amount of water that must be consumed daily, but there is general agreement on what a healthy fluid intake is.90003 90002 According to the U.S. National Academies of Sciences, Engineering, and Medicine, the average recommended daily intake of water from both food and drink is: 90003 90002 This would be around 15.5 cups for men and just over 11 cups for women. However, around 80 percent of this should come from drinks, including water, and the rest will be from food. 90003 90002 This means that: 90003 90010 90011 Men should drink around 100 ounces, or 12.5 cups of fluid 90012 90011 Women should drink around 73 ounces, or just over 9 cups 90012 90021 90002 Fresh fruits and vegetables and all non-alcoholic fluids count towards this recommendation.90003 90002 Times when it is most important to drink plenty of water include: 90003 90010 90011 when you have a fever 90012 90011 when the weather is hot 90012 90011 if you have diarrhea and vomiting 90012 90011 when you sweat a lot, for example, due to physical activity 90012 90021 90002 Here are some facts about water: 90003 90010 90011 Babies and children have a higher percentage of water than adults. When babies are born, they are about 78 percent water, but this falls to 65 percent by the age of 1 year.90012 90011 Fatty tissue has less water than lean tissue. 90012 90011 Men have more water than women, as a percentage. 90012 90021 90008 Do we drink enough water? 90009 90002 A study carried out by the Centers for Disease Control and Prevention (CDC) in 2013 analyzed data from the National Cancer Institute’s 2007 Food Attitudes and Behaviors Survey. 90003 90002 Out of a sample of 3,397 adults, the researchers found: 90003 90010 90011 7 percent of adults reported no daily consumption of drinking water 90012 90011 36 percent of adults reported drinking 1-3 cups of drinking water a day 90012 90011 35 percent of adults reported drinking 4-7 cups of drinking water a day 90012 90011 22 percent of adults reported drinking 8 cups or more a day 90012 90021 90002 People were more likely to drink less than 4 cups of drinking water daily if they consumed 1 cup or less of fruits or vegetables a day.90003 90002 The study only measured the intake of drinking water. Fluid can be gained from other beverages, but water is best because it is calorie-free, caffeine-free, and alcohol-free. 90003 90002 Seven percent of respondents reported drinking no water at all daily, and those who drank a low volume of water also consumed less fruit and vegetables. This suggests that a certain number of people are risking their health by not getting enough fluid. 90003 90002 Even if the respondents reporting low levels of water intake were obtaining enough fluid, it is likely that they would be obtaining it from sources that could potentially compromise their health in other ways.90003 90002 «The biologic requirement for water may be met with plain water or via foods and other beverages,» write the study authors. «Results from previous epidemiologic studies indicate that water intake may be inversely related to volume of calorically sweetened beverages and other fluid intake.» 90003.90000 Drinking Water FAQ | Drinking Water | Healthy Water 90001 90002 Frequently Asked Questions 90003 90004 General 90005 90006 Where does my drinking water come from? 90007 90006 The drinking water that is supplied to our homes comes from either surface water or ground water. Surface water collects in streams, rivers, lakes, and reservoirs. Ground water is water located below the ground where it collects in pores and spaces within rocks and in underground aquifers. We obtain ground water by drilling wells and pumping it to the surface.90007 90006 Public water systems provide water from surface and ground water for public use. Water treatment systems are either government or privately-held facilities. Surface water systems withdraw water from the source, treat it, and deliver it to our homes. Ground water systems also withdraw and deliver water, but they do not always treat it. For more information on public water systems, visit CDC’s Public Water Systems page. For more information on how public water systems treat water, visit CDC’s Water Treatment page.90007 90006 A private well uses ground water as its water source. Owners of private wells and other individual water systems are responsible for ensuring that their water is safe from contaminants. For more information on private wells and individual water systems, visit CDC’s Private Wells page. 90007 90006 Top of Page 90007 90004 Public Water Systems 90005 90006 What type of health issues can be related to water quality? 90007 90006 The presence of certain contaminants in our water can lead to health issues, including gastrointestinal illness, reproductive problems, and neurological disorders.Infants, young children, pregnant women, the elderly, and immunocompromised persons may be especially at risk for becoming ill after drinking contaminated water. For example, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Federal law requires that systems reduce certain contaminants to set levels, in order to protect human health. 90007 90006 Top of Page 90007 90006 How do I know that the water in my home is safe to drink? 90007 90006 The United States Environmental Protection Agencyexternal icon (EPA) is responsible for making sure that public water supplies within the United States are safe.In 1974, Congress passed the Safe Drinking Water Actexternal icon. This law sought to protect the nation’s public drinking water supply by giving EPA authority to set the standardsexternal icon for drinking water quality and oversee the states, localities, and water suppliers who implement those standardsexternal icon. In тисяча дев’ятсот вісімдесят шість and 1996 року, the law was amended to protect drinking water and its sources, which include rivers, lakes, reservoirs, springs, and ground water wells. 90007 90006 Top of Page 90007 90006 How do contaminants (germs and chemicals) get into my drinking water? 90007 90006 There can be many sources of contamination of our water systems.Here is a list of the most common sources of contaminants: 90007 90034 90035 Naturally occurring chemicals and minerals (for example, arsenic, radon, uranium) 90036 90035 Local land use practices (fertilizers, pesticides, livestock, concentrated animal feeding operations) 90036 90035 Manufacturing processes 90036 90035 Sewer overflows 90036 90035 Malfunctioning wastewater treatment systems (for example, nearby septic systems) 90036 90045 90006 Many contaminants that pose known human health risks are regulated by the United States Environmental Protection Agency (EPA).EPA makes sure that water meets certain standards, so you can be sure that high levels of contaminants are not in your water. 90007 90006 Top of Page 90007 90006 Who do I need to contact to find out more information about water quality in my area? 90007 90006 Every community water supplier must provide an annual report, sometimes called a Consumer Confidence Report, or «CCR,» to its customers. The report provides information on your local drinking water quality, including the water’s source, contaminants found in the water, and how consumers can get involved in protecting drinking water.90007 90006 Top of Page 90007 90006 How often does our public water system test our drinking water? 90007 90006 Frequency of drinking water testing depends on the number of people served, the type of water source, and types of contaminants. Certain contaminants are tested for more frequently than others, as set forth by the Safe Drinking Water Actexternal icon. You can find out about levels of regulated contaminants in your treated water for the preceding calendar year in your annual Consumer Confidence Report (CCR).90007 90006 Learn more about your CCR and water quality in your area.external icon 90007 90006 Top of Page 90007 90006 What common contaminants are included in this testing? 90007 90006 The EPA sets standards and regulations for the presence and amount of over 90 different contaminants in public drinking water, including E.coli, Salmonella, and Cryptosporidium species. More information regarding the specific contaminants and maximum contaminant levels can be found on the EPA’s website (Drinking Water Contaminant Candidate List and Regulatory Determinationsexternal icon).90007 90006 Top of Page 90007 90006 What should I do if I want my household water tested? 90007 90006 The United States has one of the safest public water supplies in the world. However, if you are concerned about contaminants in your home’s water system, contact your state drinking water certification officer to obtain a list of certified laboratories in your state. Depending on how many contaminants you wish to test for, a water test can cost from $ 15 to hundreds of dollars. The Safe Drinking Water Hotlineexternal icon can give you information on testing methods.90007 90006 Top of Page 90007 90006 Who should I contact if my water has a funny smell, taste, or appearance? 90007 90006 A change in your water’s taste, color, or smell is not necessarily a health concern. However, sometimes changes can be a sign of problems. If you notice a change in your water, call you public water system company. 90007 90006 If you want to test your water, your local health department should assist in explaining any tests that you need for various contaminants. If your local health department is not able to help you can contact a state certified laboratory to perform the test.To find a state certified laboratory in your area call the Safe Drinking Water Hotline at (800) 426-4791 or visit the State Certified Drinking Water Laboratoriesexternal icon list. 90007 90006 Top of Page 90007 90006 How can I find out if there has been a violation in our public water standard? 90007 90006 When water quality standards have not been met, your public water system must notify you through the media (television or radio), mail, or other means. Your annual Consumer Confidence Report (CCR) is another way to find out about the water quality in your area.It provides information regarding contaminants, possible health effects, and the water’s source. 90007 90006 Top of Page 90007 90006 How do I find out if there is a boil water advisory or other water advisory in my community? 90007 90006 Your public water system is responsible for notifying residents if the water quality does not meet United States Environmental Protection Agency (EPA) or state standards or if there is a waterborne disease emergency. The EPA sets guidelines for when residents must be notified depending on the seriousness of a contamination event.90007 90006 You should be notified by the media (TV, radio), mail, or other means. For more information, see CDC’s boil water advisories page. 90007 90006 There are three levels of public notification. A Tier 1 notification pertains to the most serious and acute contamination events. Notification must be broadcast by local media within 24 hours. Tier 2 allows for a 30-day notification. Tier 3 provides notification through the annual Consumer Confidence Report (CCR). 90007 90006 Top of Page 90007 90006 If there is a boil water advisory in my community, how do I disinfect my drinking water? 90007 90006 In order to disinfect your drinking water during a boil water advisory, you should boil your water at a rolling boil for at least one minute (at altitudes greater than 6,562 feet (> 2000 meters), boil water for 3 minutes).Boiling your water for at least one minute at a rolling boil will inactivate all harmful bacteria, parasites, and viruses from drinking water. 90007 90006 Chemicals (for example, bleach) are sometimes used for disinfecting small volumes of drinking water for household use. The parasite 90105 Cryptosporidium 90106 can survive a long time, even after the water is treated with chlorine or iodine. 90105 Cryptosporidium 90106 can be removed from water by filtering through a reverse osmosis filter, an «absolute one micron» filter, or a filter certified to remove 90105 Cryptosporidium 90106 under NSF International Standard # 53 for either «cyst removal» or «cyst reduction.»See A Guide to Water Filters. Filtering does not remove bacteria and viruses. Ultraviolet light treatment of water is not effective against 90105 Cryptosporidium 90106 at normally used levels. 90007 90006 Top of Page 90007 90002 Wells 90003 90006 What are the main types of ground water wells? 90007 90006 According to the United States Environmental Protection Agency (EPA), there are three basic types of private drinking wells dug, drilled, and drivenexternal icon. Proper well construction and continued maintenance are keys to the safety of your water supply.It is important to know what type of well you have. Well type affects how likely your water is to become contaminated and what kind of maintenance procedures you should follow. You may be able to determine the type of well you have by looking at the outer casing and cover of the well. 90007 90006 Top of Page 90007 90006 As a private well owner, should I have my well tested? 90007 90006 Yes, as a private well owner, you are responsible for testing your well to ensure that your well water is safe to drink.The United States Environmental Protection Agency (EPA) is responsible for making sure that the public water supply within the United States is safe. However, the EPA does not monitor or treat private well drinking water. For information on testing your well water, visit Drinking Water’s Well Testing page. 90127 Top of Page 90007 90006 How do contaminants (germs and chemicals) get into my well water? 90007 90006 A private well uses ground water as its water source. There are many sources of contamination of ground water.Here is a list of the most common sources of contaminants: 90007 90034 90035 Naturally occurring chemicals and minerals (for example, arsenic, radon, uranium) 90036 90035 Local land use practices (fertilizers, pesticides, livestock, animal feeding operations, biosolids application) 90036 90035 Manufacturing processes 90036 90035 Sewer overflows 90036 90035 Malfunctioning wastewater treatment systems (for example, nearby septic systems) 90036 90045 90006 The United States Environmental Protection Agency (EPA) does not regulate private wells.You are responsible for testing your well water and making sure it is safe. 90007 90006 Top of Page 90007 90006 My well water has a funny smell or taste; should I worry about getting sick? 90007 90006 Any time you notice a significant change in your water quality, you should have it tested. A change in your water’s taste, color, or smell is not necessarily a health concern. However, sometimes changes can be a sign of problems. 90007 90006 Top of Page 90007 90006 What germs and chemicals should I test for in my well? 90007 90006 Several water quality indicators (WQIs) and contaminants that should be tested for in your water are listed below.A WQI test is a test that measures the presence and amount of certain germs in water. In most cases, WQIs ​​do not cause sickness; however, they are easy to test for and their presence may indicate the presence of sewage and other disease-causing germs from human and / or animal feces. For more information on these contaminants and WQIs, please see the Drinking Water’s Well Testing page. 90007 90006 90160 Water Quality Indicators: 90161 90007 90034 90035 Total Coliforms 90036 90035 Fecal Coliforms / 90105 Escherichia coli (E.coli) 90106 90036 90035 pH 90036 90045 90006 90160 Contaminants: 90161 90007 90034 90035 Nitrate 90036 90035 Volatile Organic Compounds (VOCs) 90036 90045 90006 Other germs or harmful chemicals that you should test for will depend on where your well is located on your property, which state you live in, and whether you live in an urban or rural area. These tests could include testing for lead, arsenic, mercury, radium, atrazine, and other pesticides. You should check with your local health or environmental department to find out if any of these contaminants are a problem in your region.90007 90006 Please remember that if your test results say that there are germs or chemicals in your water, you should contact your local health or environmental department for help in interpreting the test, receive guidance on how to respond to the contamination, and test your water more often. 90007 90006 Top of Page 90007 90006 When should I have my well tested? 90007 90006 You should have your well tested once each year for total coliform bacteria, nitrates, total dissolved solids, and pH levels.If you suspect other contaminants, you should test for those as well. However, spend time identifying potential problems as these tests can be expensive. You should also have your well tested if: 90007 90034 90035 There are known problems with well water in your area 90036 90035 You have experienced problems near your well (i.e., flooding, land disturbances, and nearby waste disposal sites) 90036 90035 You replace or repair any part of your well system 90036 90035 You notice a change in water quality (i.e., taste, color, odor) 90036 90045 90006 Top of Page 90007 90006 Who should test my well? 90007 90006 State and local health or environmental departments often test for nitrates, total coliforms, fecal coliforms, volatile organic compounds, and pH (see above). Health or environmental departments, or county governments should also have a list of the state-certified (licensed) laboratories in your area that test for a variety of Water Quality Indicators (WQIs) and contaminants. 90007 90006 For more information, visit one of the links below or contact your local health department or the EPA Safe Drinking Water Hotline at (800) 426-4791.90007 90006 Top of Page 90007 .
