Slow sand filters | Construction and DIY projects | Forums

We had a discussion last night on slow sand filters. Khun has a laundry next door who's greywater runs onto his property and he would like to utilize it. I recommended this book, I have it in my library and it's probably one of the best ones I have seen on the subject.

This website gives a basic run down on the book

you can also order pre made ones for a house size all the way up to a large community size, last time I looked at the prices they started around 900 dollars I believe

like chia had pointed out if you want to use your grey water you want to filter out any solids, I know mike reynolds and chiras use basically a cheese cloth bag to filter, a example can be seen here

we had also touched briefly on solar distillation and uv treatment

Chia has designed a industrial water recycling process at a washer and dryer manufacturer for their test units

also this book by mike reynolds goes in depth into the grey water systems incorporated in earthships
