Бурение и обустройство скважины на воду

 

 

  После того как Вы заключаете договор с нашей компанией, на участок приезжает специальная техника, которая начинает бурить скважину. После бурения и промывки скважины до визуально чистой воды,  происходит второй этап —  обустройство (монтаж водоподающего оборудования). Чаще всего производится обустройство скважины с кессоном, так как на сегодняшний день это самый оптимальный и безопасный метод, защищающий  артезианскую скважину от промерзания, что позволяет комфортно пользоваться водой из источника в автоматическом режиме круглогодично. 

 

 

   Кессон – это резервуар, что-то типа металлического ящика, который защищает скважину от замерзания при низких температурах в зимний период, поскольку устанавливается на глубину ниже промерзания грунта. В нем устанавливается все необходимое оборудование. Именно по такому принципу бурится самая популярная артезианская скважина (на известняк).

 

 

 Также пользуется популярностью менее затратный способ обустройства скважины без кессона — «под адаптер» — все оборудование и автоматика устанавливается в доме или в другом специальном помещении (по желанию заказчика), данный вариант также предусматривает круглогодичное пользование водой при наличии отопления в помещении, но требуется дополнительное место для размещения водоснабжающего оборудования.

 

   Летнее обустройство скважины (колонка) является самым экономичным способом забора воды из артезианского источника, но имеет ряд своих недостатков: предназначено для дачного сезонного использования (весна-лето), то есть при плюсовых температурах окружающей среды, отсутствие автоматического режима водообеспечения, нет ввода магистрали в дом.

Driven wells are created by driving a small diameter pipe into soft earth (gravel or sand) and are generally 30’-50 ‘deep. The most common method of well construction in the United States today is drilling, which requires a fairly complicated and expensive drill rig, usually mounted on a large truck. Drilled wells are typically 100’-400 ‘deep but can be 1,000’ or more. The U.S.Geological Survey provides an overview of types of wells 90040 [1] 90041 and the Environmental Protections Agency provides a glossary 90040 [2] 90041 of well-related terms. Typical costs: 90007 90008 90005 90006 90048 90049 Prices for drilling a water well are typically quoted by the foot, and vary significantly depending on the type and difficulty of the material being drilled through (sand, solid rock, clay, etc.). 90050 90049 Drilling the well hole, installing the casing (a tubular lining that prevents the well hole from collapsing) and adding a well cap (a tight-fitting, vermin-proof top seal) typically costs 90052 $ 15- $ 30 90053 per foot, or 90052 $ 1,500- $ 3,000 90053 for a 100 ‘deep well, and 90052 $ 6,000- $ 12,000 90053 for a 400’ well.(However, if the geological conditions are especially difficult or access is extremely limited, drilling can cost 90052 $ 30- $ 50 90053 a foot or more.) For example, the sustainable Arizona homesteaders at ByExample.com 90040 [3] 90041 report paying 90052 $ 6,750 90053 to have well drilled 280 ‘deep, or about 90 052 $ 24 90053 / foot. 90050 90049 A complete water system is typically designed (and a total price quoted) after the well is successfully drilled and the well’s depth and water yield is known.A well pump to bring the water to the surface, a pressurized storage tank or tanks (if the well’s yield is not enough to meet peak demand), underground piping to take the water to the house, electrical wiring to power the system, a control panel and other items can add 90052 $ 2,000- $ 8,000 90053 or more to the total cost, depending on the size of pump and the distance to the house. This brings the typical total for drilling a well and setting up a private water delivery system to 90052 $ 3,500- $ 20,000 90053 or more, but an especially deep and difficult well with a complex water system can cost 90052 $ 20,000- $ 50,000 90053 or more, depending on depth, water yield and system complexity.A great deal depends on local geological conditions. For example, Cushing & Sons Well Drilling 90040 [4] 90041 in New Hampshire estimates an average cost of 90052 $ 5,000 90053 for a complete water well system in that area, while a Colorado landowner 90040 [5] 90041 reports costs of 90052 $ 14,000 90053 to drill a 600 ‘well (about 90052 $ 23- $ 24 90053 / foot) and another 90052 $ 7,000- $ 8,000 90053 for a constant pressure pump system with a 70’ water line to the house, or 90052 $ 21,000- $ 22,000 90053 total.90050 90089 Related articles: Well Pump, Water Testing and Treatment, Cistern, Rain Harvesting 90007 90008 90005 90006 What should be included: 90007 90008 90005 90006 90048 90049 The Kansas Geological Society explains how to evaluate 90040 [6] 90041 the potential for a water well and a video by the American Groundwater Turst provides an overview of well water systems, including drilling methods. 90050 90049 It can take one to several days to drill a well and install the casing, depending on the final depth needed.Typically the drill rig sits on a large truck, which the crew will position on the selected site, then drill until water is reached. ByExample.com 90040 [7] 90041 in Arizona reports that it took two days to drill a 280 ‘well and one day to set the casing with concrete. 90050 90049 In some areas it is illegal to construct any kind of well without first obtaining a permit, and most jurisdictions specify how far the well must be from existing buildings, roadways, animal enclosures, a septic system or other installations.The Water Systems Council provides a tool to determine which state well codes apply 90040 [8] 90041. 90050 90089 Shopping for well drilling: 90007 90008 90005 90006 90048 90049 Search for local water well contractors through the National Ground Water Association 90040 [9] 90041. The association also provides a state-by-state list of well-water-related resources, including licensing agencies for geologists, engineers, and contractors; regulatory agencies; groundwater-use summaries; and groundwater-quality reports.90050 90049 The well driller should provide a written contract listing the work to be done and the specific costs, including potential fees for drilling deeper or drilling a second well if the first must be abandoned.

There are different digging methods used and for the traditional method, a water well is created using wide holes with 10 ‘to 30’ deep. In the United States, the most common method used is through drilling. This method uses drill rig which is quite expensive. The rig is mounted on a truck and can dig up to 100 ‘to 400’ deep or even more. So, how much does it cost to dig a well? 90004 90005 90006 Different Types of Wells 90007 90008 90002 There are three different types of wells which include dug wells, drilled wells and driven wells.How are they different? 90004 90002 Dug Wells: This is the oldest type of well as the wells are lined in the top using materials like concrete or 90012 bricks. These materials keep the water from infiltrating the well. 90004 90002 Drilled wells: This is the most common type of well used these days and they can go really deep into the ground. 90004 90002 Driven Wells: Using a certain perforated pipe, it is pounded deep into the ground. This type of well is not too common. It is a better option if the aquifer is shallow.90004 90005 90006 Average Costs To Dig A Well 90007 90008 90002 The well drilling cost varies depending on the method used. The price is also rated based on foot, difficulty level and the materials used. For instance, in drilling the hole and the installation of the case as well as a well cap, the water installation cost is around $ 15 to $ 30 per ft. For 100 ‘deep well, it could cost more ranging from $ 1,500 to $ 3,000. It could cost even more for a deeper well. Then again, there are instances where in the areas are difficult to access, so the well drilling cost is much more expensive.90004 90002 When it comes to digging a well, the total cost does not only comprise the drilling and the water installation cost. Once the well is drilled, a water system is created. The complete water system costs about $ 2,000 to $ 8,000 which includes electrical wiring, control panel and pump among many others. For a water delivery system (private), the cost ranges from $ 3,000 to $ 20,000. A much more intricate water system could cost more between $ 20,000 to $ 50,000. The cost of the water system depends on various factors like complexity, yield and depth.You also have to factor in the cost of a pump system ranging from $ 7,000 to $ 8,000. 90004 90026 90006 What to Expect 90007 90029 90002 The Kansas Geological Society provides the necessary information that you need to know about drilling methods. How long will it take to drill a well? It usually takes several days including the installation of the casing. The drill rig is mounted on the truck and positioned on the target area. There are certain areas that would require permit and there are also regulations.There is a tool provided by the Water Systems Council to help you with the state code pertaining to digging a well. 90004 90026 90006 Searching for a Well Drilling Contractors 90007 90029 90002 Well drilling is quite expensive. So, you would not want to take any chances. Make sure that you only get a certified, professional and reliable contractor who can do the job. Where do you find that contractor? You can start looking at the National Ground Water Association. They provide a list of resources, licensing agencies and other reports that you need in order to get to know more about the different contractors and methods used.90004 90002 Contractors will, in turn give you a written contract stating the complete details of the work and the costs. The contract also includes the potential fees. 90004 90040 90006 Hiring a Water Well Contractor 90007 90043 90002 Before selecting a contractor, it actually helps to have at least set of information and to have several contractors. You can search the web for contractors. Look at the license number and you can also read reviews and feedback. To help you get the best contractor, there are important considerations.For one, you need to make sure that the contractor has the necessary licenses and permit to operate. You need to know that the contractor is certified by the National Ground Water Association. The highest level given to a contractor is the Master Ground Water Contractor. 90004 90002 Aside from the license of the contractor, you also need to know if they submit well logs and if they have enough equipment. How about worker’s compensation insurance? These small details might appear to be unimportant, but in the event that something happens at least you know the workers are insured and covered.90004 90026 90006 Itemizing Costs 90007 90029 90002 When you have finally hired a contractor and there is the written contract, take the time to review it and make sure that the costs are itemizes. 90004 90002 The list could include the cost of drilling per foot, casing per foot and the cost of materials used like well cap, grout and drive shoe. The contractor may also include other costs for operations like test pumping, disinfection and grouting. In the written contract, it should also state what costs are not included in the given specifications.90004 90040 90006 Checklist for Finished Well 90007 90043 90002 After the job is finally done and prior to the contractor pulling put the equipment, you should make a final inspection. Have a list of items to check to ensure that the work is properly and completely done. First is to check the depth of well. Check the measurement against the report given to you. The second is to check the well yield. You can ask the contractor as to how many gallons in a minute. In addition to the well depth and yield, look at the well cap.Make sure that the well is capped and that it is secured. The cap should be at least 6 inches above the ground. You can also ask the contractor if the well’s disinfected. Last but not the least, you should have a well record. Get a copy from the contractor. Keep the well record for future use. 90004 .90000 Learn Which Well Type is Best For You 90001 90002 90003 In This Article 90004 90005 Aquifers 90005 Siting a Well 90005 Dug Wells 90005 Driven Wells 90005 Drilled Wells View all WATER WELL articles 90010 90002 Wells can vary a great deal in depth required, flow rate , and water quality. Before buying a lot with a well in place, you should get the reported flow rate in writing and an up-to-date water quality report, readily available from most municipal health departments.Ask the local health inspector about their water testing procedures, which are usually inexpensive and well worth the cost and effort. If problems are detected with the water quality, these need to be identified and resolved before proceeding. 90010 90002 Also pay attention to the flow rate. While a good flow rate today does not guarantee a good flow rate in other seasons, an experienced local well driller should be able to give you a good idea about the flow characteristics of wells in your vicinity and alert you to any potential problems.90010 90002 If there is no well in place, you should talk to at least two well drillers in the area, as well as neighbors, about well depths, flow rates, and water quality in the area. Get both the hands-0n prospective of local well drillers and the more scientific opinions of geologists and hydrologists. 90010 90002 The state or local office of water resources or geology may also be able to assist you with water maps and other information about available groundwater. Another place to look for help is a Cooperative Extension or School of Agriculture at a local university, which probably employs one or more hydrologists, who study water resources for a living.They can provide a good indication of whether and how you will be able to meet your water needs. 90010 90002 For example, if you need a lot more water than your nearest neighbors, you may need to drill deeper or drill more than one well. If a very deep well is needed, you will need to budget accordingly. However, well drilling is based on an educated guess of underground conditions — there are no guarantees. 90010 90002 If you do not yet own the land, and the availability of adequate water is in question, you may want to make your bid contingent upon drilling a test well of sufficient flow rate and water quality.This will cost you few thousand dollars, but could save you many thousands more. 90010 90002 90003 AQUIFERS 90004 90005 Aquifers are natural areas of water storage under the ground. While many people think of aquifers as underground pools, they typically consist of areas of permeable sand 90010 The water table forms the top of an unconfined aquifer where the water must be pumped to the surface. Where the water is confined between impermeable layers, the water may rise to surface under natural pressure, creating and artesian well.CLICK TO ENLARGE Courtesy of USGS 90002 and gravel, and cracks in solid rock where water is able to slowly flow. How much water the rock and granular soil can hold depends on how much open space exists between the particles, called its 90029 porosity 90030. This ranges from 0 in solid rock to about 30 or 40 percent in gravel and sand. 90010 90002 Aquifers have a bottom, where the soil or rock is impermeable, and a top, called the water table. The water table may rise to the surface of the earth at a natural spring, or at a pond or lake, but usually it is well below the surface.90010 90002 90035 Water tables can be a few feet thick or hundreds of feet from top to bottom and can range in area from the size of a pond to hundreds of miles across. Aquifers are replenished primarily by rainwater that percolates through the soil. 90010 90002 90003 90029 Unconfined vs. Confined Aquifers 90030 90004. In an unconfined aquifer, the top of the aquifer is the water table and the water must be pumped upward (see Illustration). If an aquifer is confined between bedrock and another layer of impermeable material, such as clay, the water may be under pressure and rise above the aquifer when drilled into.In some cases, the water will rise all the way to surface without a pump, creating an 90029 artesian well 90030. 90010 90002 To reach the aquifer, you may need to drill 30 feet or 500 feet. Aquifers tend to follow the slope of the land above and water tends to move slowly through the aquifer following the slope. The rate of flow depends largely on the permeability of the rock and other material in the aquifer. When water is pumped from the aquifer by a well, it is drawn down in a area around the well.The more permeable the material in the aquifer around the well, the faster the well area will be replenished and the greater the well’s flow rate. 90010 90002 Depending on the geology, there may be and adequate supply of pure water relatively near the surface, or you may need to drill into deep water-bearing rock to get adequate flow and flow. Based on their knowledge of local conditions, an experienced well driller or hydrologist can help determine the best strategy. 90010 90002 90003 SITING A WELL — WHERE TO DRILL 90004 90005 A knowledgeable well driller, or if necessary, a hydrogeologist or hydrologist, should be consulted to help site your well.You may be able to get some technical support for free from a local or state office of geology or water resources or from a nearby school of agriculture or natural resources. Where to drill for water is an important decision. In some cases, with a well-mapped aquifer and many wells nearby, it is highly probably that you will hit good water at a certain depth. In arid regions with few wells nearby, it may be less clear. In this business, however, there are no guaranties that you will find water of sufficient yield and quality — or find it at all.So take you time in choosing a well site. 90010 90002 Your goal is to determine what location, depth, and well diameter is most likely to provide the best flow rate and water quality for the least money. It is important to maintain adequate clearance from septic tanks, leach field, roadways, and agricultural uses such as pastures and silos. In some cases, the building code will specify a minimum depth, setback from the property line, and distance from septic systems and other sources of contamination.90010 90002 Some jurisdictions require the well to be uphill from the septic system, a commonsense idea, but not always feasible on small lots where you will inevitably be downhill from someone else’s septic system if not your own. Regardless of code requirements, you will want to follow industry standards and a professional’s recommendations for a safe and dependable water source. 90010 90002 There are also practical concerns about distance from the house and access of drilling equipment and for maintenance.A site far from the house will increase the costs of wiring and plumbing from well to house. In addition, you may have preferences, such as not wanting the well in your front yard or in the middle of your future garden — so make sure you approve of the well site before drilling begins. 90010 90002 90003 DUG WELLS 90004 90005 In some rural areas, homeowners still get their water from shallow, dug wells. Historically, these were dug by hand to just below the water table and lined with fieldstone, brick, or interlocking concrete tile (in newer wells), and capped with wood, stone, or concrete cover.They were typically 3 or 4 feet in diameter and typically from 10 to 30 or so feet deep, but in some cases were over 50 ft. deep. In the old days, a bucket or hand pump was commonly used, but most now use an electric pump. 90010 90002 Dug wells typically penetrate into just the top layer of the aquifer or into a small perched water table, which is separated from the larger aquifer below by an impermeable layer of soil. Water levels in these wells tend to fluctuate with seasonal variations in the water table and may dry up during extended dry spells.Modern shallow wells are typically excavated or bored with power equipment and lined with concrete tile. Because these can go deeper into the water table, they can produce a more reliable water supply than hand-dug wells. 90010 90002 Because traditional dug wells typically draw on shallow groundwater and lack a continuous casing, they are highly susceptible to contamination from nearby septic systems and from surface sources such as agricultural runoff, lawn chemicals, and other pollutants. However, dug wells can produce high-quality water they are designed and located properly.90010 90002 Dug wells should have a sealed casing and cover, and be located at least 25 feet away from ponds or streams. They should be uphill from and at least 100 feet away from sources of contamination including septic systems, livestock, and fuel tanks. If located on a slope, create a berm of clay soil around the the well to divert surface runoff away from the well (see illustration). 90010 If used for drinking water, a dug well should have a watertight case and concrete cap. The space between the well casing and borehole should be sealed with cement grout or bentonite clay.Source: US EPA CLICK TO ENLARGE 90002 For safety and good performance, dug wells used for drinking water should 90010 90002 • be dug during the dry season to reach deep enough into the water table 90005 • have a watertight casing, such as large-diameter precast-concrete pipe, which sits on a sand or gravel base at the well bottom 90005 • be disinfected with chlorine when new or after repairs are made 90005 • be located on high ground, not subject to flooding, and sloped away in all directions from the well 90005 • have a tight-fitting metal or concrete cover at the top of the casing, about one foot above the ground 90005 • have a pump in the inside your house or in a pump house to protect equipment, storage tank, and piping 90005 • use a pitless adapter in cold regions to provide a frost-proof, sanitary seal to the water line 90005 • be 100 feet away from farm animals, cesspools, or leach fields 90005 • be 75 feet away from property you do not control 90005 • be 25 to 50 feet away from drainage ditches, culverts, streams, or ponds 90005 90003 90005 DRIVEN WELLS 90004 90005 Where conditions are right, driven wells may offer an an economical alternative to a drilled well.Also called «sand point» wells, these are often used for cabins or vacation cottages where there is groundwater within 15 to 30 feet of the surface. They are made by driving a small-diameter pipe, by hand or power tools, into water-bearing sand or gravel that lies above the bedrock. A screened well point, designed to filter out sediment, is typically attached to the bottom of the pipe before driving. 90010 90002 Under favorable conditions, the pipe can be driven up to about 30 feet by hand, and 50 or more feet with a powered post driver.Typically, installers use five- or six-foot lengths of galvanized pipe with a cap on the end being hit to prevent damage to the threads. Each new section of pipe is added with a coupling to the one below. Sandy soils are the easiest to drive through. Clay will require power equipment. 90010 90002 There are a variety of ways to complete a driven well. Often the connection to the discharge pipe is made underground using a pitless adaptor. The access pit must be dug around the well to below the frost line in cold climates.Depending on local codes the pit can later be backfilled or can be lined with concrete tile and cap, similar to a dug well. The pump may be located inside the home or on top of the well within the concrete tile or a pump house. 90010 90002 Because these wells are simple and inexpensive, some people drill two and plumb them together for a better yield. However, like dug wells, they reach only shallow water, making them susceptible to contamination from surface sources. 90010 Most modern wells are drilled by rotary drills to a depth of 100 to 500 feet to reach the water table.The bottom of the well may be in granular material or fractured rock. Courtesy of American Groundwater Trust 90002 90003 DRILLED WELLS 90004 90005 Over 15 million homes in the US draw their water from private wells and millions more use water drawn from municipal wells. Nearly all of these are drilled wells (see illustration). Most modern wells are drilled by rotary drill machines, which can easily drill through solid rock. 90010 90002 In some cases, a cable-tool drilling rig is used, also referred to as a percussion or «pounder» machine.In this technique, a heavy bit attached to the bottom of a wire cable is repeatedly raised and dropped, pounding its way down through the earth. Most private wells range from 100 to 500 feet deep, but in rare cases can exceed 1,000 feet. 90010 90002 90035 The well design will depend on the specific geological conditions at the site. Most wells are drilled an inch or two wider than the casing diameter, which is commonly 6 inches. In the upper portion of the well, unless it is solid rock, the space between the casing and the drilled hole is later «grouted» with cement or bentonite (a special expansive clay).This seals the drilling hole to prevent contaminated surface water from migrating down the well casing to the aquifer. Depending on conditions, the bottom of the well may be drilled into solid rock, drawing its water from cracks in the rock. 90010 90002 90003 90004 90010 90002 Back to Top 90010.90000 Water Wells — Everything You Need to Know 90001 90002 Making your offer contingent on the seller drilling a satisfactory well would be great if he agrees to your terms. In any case, it’s definitely a good idea to add some type of water well contingency to your offer. However, drilling a separate test well prior to the water well is usually done only for municipal or high-yield agricultural wells. 90003 90002 If you plan to drill a well prior to purchasing, then the contingency could state something like «Driller is to find well water at a depth, flow rate, and quality satisfactory to the buyer.»Or you could add specific numbers, such as a minimum flow rate of 5 gpm of potable water at less than 300 feet. 90003 90002 The well contractor would then drill to a suitable depth and perform a «drawdown» test to establish the flow rate. The water quality can usually be tested through the local health department for a small fee. 90003 90002 If you do not want to incur the cost of drilling a well ahead of time, you can hire an engineer to evaluate the prospects of drilling a satisfactory well based on the local geology, aquifer conditions, and performance of surrounding wells.In some states, well data are public records, and there are additional groundwater data available from the US Geological Survey, state geology departments, and local universities. Licensed well drillers in the area can also be an excellent source of information on the depth, yield, and water quality of surrounding wells. 90003 90002 While no one can establish with 100% certainty what your drilling results will be, the performance of surrounding wells and geological data can provide a high level of confidence in most cases.Your contingency might read something like: «Engineer shall establish the feasibility of an adequate private water supply to the satisfaction of the owner. Owner reserves the right to enter the property to drill a test well to establish that the well depth, yield, and water quality are to the owner’s satisfaction. » Once you have established the likelihood of a suitable well, then the $ 10,000 cost may be easier to justify. 90003 90002 For 100% certainty, you’ll need to spend the $ 10,000. You can certainly ask the owner to pay for some or all of the drilling costs.Maybe he will share the cost with you 50/50. It all depends on the market, the seller’s motivation, and the attractiveness of your offer. Some land owners choose to drill a well and conduct a perc test prior to listing the lot — it certainly improves its marketability. 90003 90002 Whether it is worth risking $ 10,000 to avoid a $ 100,000 mistake, or whatever the lot costs, is a tough decision. If the seller will not cooperate, and you have serious doubts about the water, then you may have to walk away.90003 90002 Whichever approach you take, it’s always a good idea to have a lawyer review your offer to make sure that you are not putting your earnest money at risk and have an iron-clad option to back out of the deal if your land inspection is not satisfactory. 90003 90002 Best of luck with your land search! 90003 90002 90021 Read more about 90022 90021 Making An Offer On Land 90022. 90003.
