Septic tanks require the solids as well as greywater to provide food for the bacteria, so they won't work with greywater alone. Greywater harvesters are expensive and require electricity, so are not so green and in the UK and most of Northern Europe, we have more than enough water for the Gardens. Non-electric sewage treatment plants use no electricity for the process and produce clean water which can then be used for irrigation. - septic tank Tue, 19 May 2009 10:22:32 +0100 http://www.ecogeek.org/green-software/1172#comment-8539 well, thanx!
