DIY – Creating a Simple Greywater System


Here’s a simple greywater system for new homes as well as retrofits.  You can also use this system  to distribute tap water (drinking water) to the landscape.

Let’s begin with the in-ground distribution box – the distribution filter box.  We install this to be flush with the surface, and this is vital because anything sticking up causes problems.  The overall unit is durable and can withstand people stepping on the top.

The greywater flows through the distribution box, and subsequently filtered out to the Aquifer Pipes buried in the ground.


The filter box will have latches, or locks, or, as in our video, the top can be screwed on.  This set up prevents people from tampering with it.   The box is not pre-drilled, therefore you can match and size your output to the right spot.

The greywater flows through the top, through the filter, and exits out the bottom.  This is a key point:  The water must exit out of the bottom.  Because it’s a flow-through system, we don’t want greywater holding up inside.


From here, the water travels through a standard one-and-a-half inch ABS pipe (1.5″) to the Aquifer Pipe.  We bury these in series, to irrigate a nice, wide area from the lawn to the shrubs and trees.  

The greywater passes through side channels to create a central moisture point.  From here, a water plume extends four feet on each side and up to 12 inches on top.  As a result, we will feed grass roots or any type of plants above. 


The greywater filter captures the hair and the lint.  Hence, it’s easy to maintain.  The filters are affordable, from 50 cents to a dollar.  You can throw away the old one, or clean it off, and replace it.  

And when you screw your lid back on, your cisterns are ready to go!
