Greywater wetland piping and walls
I did a little reading
and pondering overnight and decided to change the shape of my greywater
wetland a bit.
It was approximately three feet wide and twelve feet long at the end of
the day Wednesday, but Create
an Oasis With Greywater recommends a width twice the
length. The upper end of the wetland is hemmed in, but I opened
it out a few feet down to perhaps five feet wide, then stomped on the
walls until they became a more gentle (hopefully mowable) slope.
next step was to consider how the water is going to get to the
wetland. We currently have two 3" pipes
running straight down from our kitchen sink. Even though it will
cost more to run both of them all the way to the wetland, keeping our
fast drainage seemed worth the hassle. We'll be using unflexible
PVC pipes that won't curve, so I pulled out some string to make
straight lines between the current sink outlet and the inlet of the
When Mark buried the
project was painful because we wanted to get the lines deep enough they
wouldn't freeze. In contrast, my greywater lines are only being
buried for convenience, so we won't trip over them and can easily mow
over the area. Freezing won't be a problem because the water will
run straight out into the wetland, so my trench is only barely deep
enough to get the pipes underground.
Here's Mark's shopping
list for today. We decided to make a T below the sink and let the
roof runoff come in there rather than running at third line for that
water. Heavy rains will hopefully flush out any gunk that may try
to build up in the lines between the sinks and the wetland.
Our chicken waterer is the POOP-free alternative to traditional filthy waterers.
