You don't have to reuse your greywater.
If you simply want greywater disposal, we can sell you a passive (gravity drainage) graywater disposal system (basic kit and filter basin plus a drywell kit).
It includes everything shown below: cleanout, filter basin, greywater filter and all of the other plumbing fittings you'll need, plus a drywell kit with vent and filter fabric for easy direct disposal of your household greywater.
Our 800-563-9720 toll-free design and installation assistance is included in every graywater disposal system we sell!
That's what makes our greywater disposal kits such a great value.
Unlike the large catalog companies we've experimented, installed, and serviced many different greywater system configurations over the years.
We have the practical knowledge to ensure your graywater disposal project's success.
Please note that even if you don't have to obtain a building permit for your greywater system now, it doesn't mean a future owner won't be required to.
We highly recommend keeping resale value and future health code enforcement firmly in mind when considering graywater irrigation.
Roof run-off cisterns are an excellent source of toilet flushing water, but recycling greywater to flush your toilet is simply not cost-effective and is potentially unhealthy.
It is much easier, less expensive, and worlds safer to directly dispose of greywater in a leaching pit or irrigation field.
Here's several classic greywater system design mistakes to avoid:

| Our passive graywater irrigation (or disposal) kits make watering your greenhouse, orchard, or planterbeds a breeze. Graywater from your home is piped directly to this extremely durable, buried vault where solid debris (lint, hair, and dirt) settles to the bottom and grease floats to the top. Yes, Grease and Fats ... some of the most popular "natural" bar soaps are 99.9% refined chicken fat. That's why you must have a settling tank or your leach field will eventually clog and fail. As greywater flows in, clarified graywater irrigation flows out. Our graywater irrigation kit works without any "moving parts". All of the fittings required to install your greywater filter/settling basin are included*: tank with lid, rubber grommets for inlet and outlet pipes, neoprene lid gasket, and tamper resistant fasteners. Replacement and/or additional fittings are common four inch diameter sewer pipe available at your local plumbing or building supply store. *You provide the straight (perforated and/or solid) sewer pipe from house to tank and from tank into leach field. |

As with any kit purchased from us, we can certainly work with you on specific site needs after purchase.
For instance, the main consideration in a cold climate is keeping frost from penetrating down into soil surrounding the settling tank.
Typically, this entails covering the area around tank (surface above) for at least three to four feet with a heavy duty tarp (8' by 8' or 10' by 10' size) to prevent moisture (frost) from being driven down to surrounding soil.
Then place an at least 2 inch thick sheet of blueboard EPS foam insulation (4' by 4' minimum) directly above tank.
You cut hole in center of sheet to slip circle of foam out for gaining access to settling tank lid.
Dry soil is key to maintaining warmth since frost only penetrates down into moist soil.
The drywell leaching pit and pipe to and from tank will not be affected by cold since it is running water, but laying the pipe in a thick gravel bed is standard practice for preventing frost from contacting the pipe (same applies to tank).
Burying the system deeper is always an option to help in cold climates, but a foot or two for the tank is typical.
Shown below is a sample installation with TWO drywells in series - bringing sewage, greywater or storm water in through the lid.
Venting your leaching pit is most highly recommended.
Oxygen keeps the storm water drainage pit dry and the soil around it healthier.
Freezing is rarely a problem with running water underground.
You can always cap the vents in deep winter, if need be.
Top loading (with vent) ensures maximum surge capacity for the drywell.
We provide all of the fittings pictured with your kit (san tee, riser, coupler, vent and geotextile fabric).
Please note the geotextile fabric is included for installation above the gravel layer.
This is necessary to extend the life of your leach field - the fabric keeps topsoil out of your gravel layer around the drywell.

Heavy-duty, recycled, high density polyethylene HDPE plastic leach pit kits come shipped in a handy carrying case ready for on-site assembly. Drywell kits are 24 inches in diameter, 28.75 inches in height (24" without lid), and weigh 23 pounds apiece. Knockouts are provided for nine - 4 inch pipes and fifty four - 1.25 inch diameter leaching holes. Initial surge is 50 gallons, but the capacity is only limited by the size of the leaching pit (dig a larger hole and add more gravel). Three interlocking side panels, heavy duty lid, FREE sanitary tee fitting for bringing liquid into the lid, FREE coupler, riser, and surface vent grate, FREE geotextile filter fabric to keep soil from entering the gravel layer around your drywell and FREE SHIPPING via UPS Ground to the lower 48 states. |
The beauty of our greywater disposal system is that you can very easily convert it to a greywater recycling system later. A row of privacy bushes or a small orchard is typically the best reuse of greywater - a fruit tree tree can easily uptake 15 plus gallons per day and the pipes do not need to be pressurized. Please take this link to a detail page with typical greywater leach field sketches. With this style of system, the drywells are acting as "emergency overflow" leaching pits - the majority of the water is being delivered directly to the trees in your orchard.

Graywater irrigation systems can be very simple and non-electric when the top of your planterbed (leach field) is below the elevation of the home's effluent pipe.
When used as the first settling tank of your greywater system, this filter basin acts as a grease trap.
Typically, a drop tee is used to introduce incoming greywater subsurface (see sketch above) and not a direct discharge inlet pipe (as shown to the left).
The direct discharge pictured here is only recommended when installing the basin in-line after an inital settling/surge tank.

Details will naturally vary with the application, but the following manufacturer's recommendations generally apply:
|
Drywells are designed to provide alternative water management solutions which reduce the need for costly labor-intensive concrete and pipe-in-trench leaching systems. These handy kits have three side panels which have been molded so that they create a solid container with tightly fitting sections. When assembling, be sure to keep the panels straight while sliding together and screw the lid down with the supplied fasteners. |
|
|
FOR USE AS A DRYWELL Knock out or cut out the 1 inch ports to allow water to drain out. Hit the "X" marks on the inside of each panel with a small hammer. Rest the outside of the drywell atop a 2 by 4 laid close to the hole being removed.
|
|
 |
Backfill evenly around the drywell, raising the level in stages to avoid tipping the unit.
|
|
Bury the drywell at least eight inches below the surface grade.
|
 
|
 |
When stacking drywells, order the set of three side panels and assemble with the full kit of three panels and lid.

Extra drywell leach pit kits are $159*

Residential home sewage system (septic) leach fields are a common usage for drywell kits (leach pits). Drywells are extremely handy for repairing a failing septic system - there is really no need to replace the existing system. If you have a failing leach field, you can attach one or more drywells to the end of one (or more) "finger" of the leach field perforated drain pipe. This is an excellent low cost way to save a failing leach field by allowing sewage to again percolate into the soil through a drywell leaching pit. As pictured below, units can be stacked and gravel placed around them to increase the amount of sewage water the leach pit system is capable of disposing.

Keep lint out of your leach field! The simplest and most effective way to ensure a healthy leach field is to put a strainer bag on your washing machine effluent. Install your utility sink next to the washing machine and attach a five gallon paint strainer bag to the effluent with a hose clamp (see left). Keep lint out of your filter basin for a smoother operating system and a healthier leach field. Laundry lint will clog a leach field faster than anything else. |
Need a pump too? If your leach field or planterbed is uphill from the filter basin, you will need a sump basin with automatic pump. The picture at left shows both sizes of basin with the pump out front. These pumps are nice in that they don't have a float switch, they automatically operate off of a pressure diaphram switch instead. This option would add $350 to the cost of your greywater recycling system. |
