To determine how many dry wells you'll need, enter your roof area and soil type into the calculator at NDS, Inc. When you're ready to start digging, follow the steps. After you're done, fit your gutters with leaf guards so that the dry well won't fill up with debris.
Can a wet walkway break apart a pavement?
Roger Cook replies: A wet walkway is not only a slipping hazard, it contributes to damaging frost heaves that can break apart pavement. If you can't relocate the downspout, route the water under your walk and out to a dry well buried in your lawn.
What is a dry well?
A dry well is a simple and clever system used for draining excess water out of a low spot or from a water-laden area such as at the foot of a downspout. A dry well is a surprisingly inexpensive system that consists of a buried drainpipe that runs from a small catch basin (where the water ponds) to a collection container ...
What to line trench with before can?
However, before the can is placed in the hole, line both the trench and the hole with landscape fabric or burlap. Be sure that the excess fabric laps over the edges of the trench. The fabric prevents surrounding earth from getting into the system and clogging it up.
How deep should a drain trench be?
The trench should be about 18 inches deep and just wide enough to hold your perforated drainpipe. The trench should slope downward as it travels from the catch basin location to the dry well. The slope should be approximately one-quarter to one-half inch per foot (more slope is better).
When does water travel along the surface?
When it rains, when snow melts and when excessive irrigation occurs, water is supposed to travel along the surface to a safe place away from the house…without puddling or ponding. But it doesn’t always happen that way. When surface water doesn’t do what it’s supposed to, you can expect problems.
Can you install an underground drainage system?
Installing a conventional underground drainage system can be difficult at best. It can involve burying hundreds of feet of pipe. And once a yard has been fully landscaped the level of difficulty increases substantially. Patios, walks, decks, sheds and fences can be insurmountable obstacles.
Can a mini storm drain be used as a trash can?
You have just created your own mini storm-drain system. Incidentally, the drainage receptacle doesn’t have to be a trash can. For smaller puddle problems, a bucket can be used. dry well ponding water drainage.
What is the purpose of a dry well?
The purpose of a dry well is to direct water away from your house (and therefore its foundation) to an area where the ground can absorb the water. For this reason, you need to identify a proper location in your back yard.
How deep should a downspout be?
The downspout is where all the water from the roof runoff and gutters comes through. Next dig a trench that is 12 inches deep and 6 inches wide from the downspout to the location of the dry well. You will need to modify your downspout slightly so it reaches the trench.
Can you build a dry well in your yard?
Keep in mind that this sort of project normally is not a do-it-yourself project. As a result, you may wish to build a dry well only after consulting with a professional.

Repeat this process until the hole is filled to the level of the trench. Put a thin layer of crushed stone in the trench.
How much of the water is backwashed?
The backwash water volume is usually 2–3% of the treatment plant flow. Spent filter backwash water will typically contain 10–20% of the total solids production, and may contain both organic solids and microorganisms as a result of biological growth from the filters.
What happens if you backwash a filter?
Attrition of more friable filter media may result from a vigorous backwash, particularly if air scour is used.
What is raw water pretreatment?
The raw water pretreatment plant is designed principally for solids removal from the incoming Hanover county sewage effluent (grey water), backwash water and wastewater from the oily water collection system. Raw water enters a coagulation/flocculation chamber followed by a clarifier and dual media depth filters. Backwash water from the filters is periodically returned to the clarifier. Clarifier sludge is dosed with polymer before being thickened and then sent to the filter press for dewatering. The cake is sent to landfill and the recovered water returned to the clarifier.
How much water is recycled in a water treatment plant?
In a survey of the 335 water treatment plants in the US that recycle spent filter backwash water, the average generation of spent waters was found to be 2.5% [73]. Most of the plants (88%) use surface water as their source, with 83% of these recycling to the head of the plant and only 2% to just before the filters. Further treatment is provided by 65% of the plants before reuse of the backwash water, the type of treatment varying from site to site. Options include sedimentation with or without added coagulants, dissolved air flotation with and without polymer, oxidation, conventional filtration and membrane filtration. Pilot studies of various methods to establish appropriate strategies showed that 0.5 mg L −1 of a cationic polyacrylamide of very high MW and medium CD removed 99.6% of the turbidity after filtration, and a similar dose of an anionic polyacrylamide removed 99.4% [ 73, 74 ]. The polymers were selected as the best options after jar tests on two cationic, three anionic and three non-ionic polymers. Similar performance was obtained with 15–20 mg L −1 of ferric chloride, but treatment effectiveness was lost soon after a steady state was achieved. Ferric chloride and a CPAM in combination, however, gave stable long-term treatment with the same turbidity result as for CPAM alone. Ferric chloride was superior for DOC removal. Generally, treatment was much better when polymer was added in both sedimentation and dissolved air flotation, which gave equivalent performances. In other work on dissolved air flotation, treatment of a high degree in a very cost effective manner was achieved, a treated water turbidity of 1 NTU being easily obtainable when the original backwash water turbidity was in excess of 50 NTU [78]. Chemical requirements were low, with no primary coagulants being added and only a single low dose (0.1–0.5 mg L −1) of polymer being required to bind the floc particles and form agglomerates that were suitable for flotation. The optimum polymer type was site specific.
How much higher is a giardia in backwash water?
In a survey of 34 water treatment plants it was found that Cryptosporidium levels were up to 61 times and Giardia levels 16 times higher in the backwash water than in the original raw water [76].
How can we conserve water resources?
In arid areas conservation of water resources can be achieved by recycling spent filter backwash waters, and this is an economic necessity in other locations also. There is a concern that such recycling can compromise product water quality because contaminants can be concentrated to a level beyond the plant's multi-barrier treatment capability, with Cryptosporidium being a particular worry. A major survey of the situation and a pilot plant study of treatment options prior to recycling have been completed recently [ 73, 74 ]. Cryptosporidium has been detected in backwash waters at a range of levels, one result being as high as 9–33 million per 100 litres [75]. In a survey of 34 water treatment plants it was found that Cryptosporidium levels were up to 61 times and Giardia levels 16 times higher in the backwash water than in the original raw water [76]. In the UK it has been recorded that a backwash water contained Cryptosporidium at 1M/100L and supernatant water decanted from a settling tank 100K/100L [77]. The most recent study puts the significantly higher levels of protozoa in backwash water than in raw water at 21 times for Cryptosporidium and 16 times for Giardia [74]. Similar trends have been observed for DOC and other contaminants.
When softening and clarification processes are carried out together, the clarifier and softener dry solids should be
If softening and clarification processes are carried out together the clarifier and softener dry solids should be summated.
What is the best way to get rid of bad water in a well?
Water softeners, whole house water filters, disinfection systems and distillers are all effective options when it comes to eliminating the bad stuff from your well water.
How to test well water?
It’s best to get your well water tested by a state-certified laboratory, as recommended by the EPA. Contact your local laboratory to see if they offer any packages for testing for multiple well contaminants at once. A lab can help you to understand the level of impurities in your water and the problems they may cause.
What are the contaminants in well water?
Some of the most important potential contaminants to test for in your well water include coliform bacteria, calcium and magnesium, lead, arsenic, iron, sulfate, nitrates, sediment, fertilizers, pesticides and herbicides, and VOCs. Varying levels of each of these impurities will cause various issues in your homes and require different forms ...
How does a whole house filtration system work?
Typically, this type of whole house filtration system uses the oxidation process to effectively eliminate these common private well water contaminants. When well water flows through an air pocket, its sulfate, manganese and iron impurities oxidize. The filter media then traps the contaminants present, allowing only clean, filtered water to pass through. Every so often, the system will automatically backwash to remove the contaminants from the media bed.
Why do wells need UV disinfecting?
Because ultraviolet water systems are naturally designed for targeting living, difficult-to-filter microorganisms in wells, they won’t remove or kill any other common contaminants that affect water quality. For that reason, many well owners combine separate UV disinfecting with a whole house water well filter or softening system for the best results.
Why isn't my well water filter removing microorganisms?
Most water filters for wells aren’t capable of removing microorganisms because they’re small enough to fit through the filter pores. Ultraviolet light, however, doesn’t filter these pathogens out of water – instead, it damages their DNA, killing them and preventing them from being able to duplicate.
How does distillation work?
This method of water treatment works by boiling water until it evaporates, then allowing it to cool and condense into a carafe.
How to fix a dry well?
Before you even encounter such a hassle of a problem, however, you can help prolong the useful life of your dry well by regularly cleaning gutters and down spouts to eliminate grime and debris early on—before they even reach the pit. If you’re using a dry well for gray water, install a filter on the drain line and clean it frequently to remove lint and soap scum that might otherwise clog it.
How does a dry well work?
That’s where a dry well comes in. A successful installation harnesses gravity to direct water toward the lowest point in the yard, where a dry well has been buried. This gives runoff water a place to collect until it gradually dissipates into the soil, instead of cascading across the lawn surface and pooling in depressed areas.
Why do you need a dry well?
Additional dry wells may be necessary if elements of your landscape are creating a drainage problem, such as runoff from a driveway or large patio. Ideally, dry wells should be large enough to collect runoff without overflowing in typical rain events. Depending on the average amount of storm water you need to control, ...
What is a dry well?
Dry wells are just one means by which homeowners can collect and control storm water runoff. They are not suitable for everyone, however, so read on to determine if it’s the best drainage solution for your yard.
How to keep water from cutting a rut?
To keep the water from cutting a rut after it leaves the downspout, you can install a simple swale (a trench filled with gravel) leading to the collection pit or a French drain. Your project should also include provisions for dispersing excess water that occurs during rain events that cause your dry well to overflow, such as an overflow pipe that leads to a storm sewer.
How does rain affect downspouts?
The same principle is at work in your own yard: Rain falls on your roof, drains to the gutters, and then rushes out of the downspouts to wherever it can drain in the soil. Even water from a gentle rain can build up force as it exits the downspouts.
How to determine if your yard needs in ground water?
To calculate this rate, you’ll conduct a percolation (perc) test in your yard—a process that involves digging a hole (or numerous holes), filling them with water, and then recording the rate at which the water seeps into the ground. Detailed instructions for performing a perc test on your own property are available from your local extension office.
