Gray Water Tips from The Rain Well


 Remove the Chlorine from Municipal Water Supply.
Use a whole house filter, such as the Aquasana Rhino, to remove chlorine from the municipal water supply.  Chlorine is added to municipal water to inhibit organic growth.  Gray water from your showers, washing machine, and baths will also contain chlorine.  Chlorine in gray water will also inhibit organic growth.  Chlorine free gray water will ensure the best possible growth for your beloved plants.
 Simple Gray Water Conversion for Every Household.
By replacing your toilets with composting toilets, your main sewer line can be converted to a gray water line!  Removing toilets keeps the black water from going to the sewer.  Connecting a gray water irrigation line to the main sewer line with a valve is all that is left to do.  The valve is used to divert the household water to the main sewer line when the dishwasher is being used, washing dishes in the sink, or washing oily clothes.  Otherwise, shower water, bathtub water, bathroom sink water, and washing machine water can be diverted to the gray water irrigation line!  During the non-growing seasons, the drainage from the household can be diverted to the sewer.  New Mexico considers dishwasher water and kitchen sink water as black water.
 Use your garden hose to drain the bathtub water.
By using a garden hose, no pump is required, because the garden hose will siphon the water from the tub through the window.  First, place the male end of the garden hose in the bathtub.  Hold  the male in down with something heavy enough to keep the hose at the bottom of the bathtub and to keep it from moving.  Next, extend the female end of the hose out the bathroom window.  If you need to take the window screen off first, then do so.  Next, connect the garden hose to an outdoor water faucet.  The hose needs to be primed before the siphoning can start.  Turning on the faucet will fill the hose up with water.  Once the hose is filled with water, detach the hose from the faucet.  Then carefully take the hose to where you want to distribute the water.  A simple pump such as the battery operated submersible utility pump can also be used to pump out the bathwater or to start the siphon process.
New Mexico Gray Water Irrigation Guidelines.
§
The gray water distribution system must be constructed so that overflow from the system drains into the sanitary sewer or septic system. In some cases, a liquid waste permit may be necessary if an on site septic system is modified.
§ A gray water storage tank must be covered to restrict access and to eliminate habitat for mosquitoes or other vectors. Standing water left in place for more than seven days has the potential to allow mosquitoes to breed and hatch.
§ The gray water system must not be located in a floodway.
§ Gray water is discharged only in areas where there is vertical separation of at least five feet between the point of discharge and the ground water table to protect ground water resources from possible contamination. Current Liquid Waste Disposal Regulations require that gray water is not applied within 100 feet of a domestic well or within 200 feet of a public water.
Use proper size hose to extend the washing machine outlet hose.
Do not use a tube that is any smaller in diameter then the washing machine outlet hose, otherwise, the pump will burn out.
Do not raise the washing machine outlet hose too much higher or it will burn out the pump.
Bury the gray water distribution tube or pipe in garden furrows with mulch.
The vegetable plants will not be splashed with gray water.
Old socks make great filters
Make sure the socks are replaced frequently.
Storage tanks must have lids.
Gray water should not be stored over 2 days.
Make sure that no harsh chemicals are being used.
Gray water will not be useful if it contains harsh chemicals.  Some detergents can add stress to plants.  There are bio-degradable detergents available.
Detergents breakdown minerals in the water.
Plant roots can absorb the water much more efficient.
