Just read the following on WTE LTD web site Sewage treatment plants must be to EN 12566 part 3 However..... EN12566 part 3 only tests the percentage reduction of the influent pollutants in the sewage and gives no guarantee the final effluent quality will satisfy the Environment Agencies final consent standards.

Thanks for the replies. Plenty for me to study. The system that uses worms (non electric) is from septictank.co.uk - there may be others, sorry do not know how to put a link up. The blurb says no maintenance required, you may never need to open the lid (or words to that effect). I emailed septictank yesterday to ask about emptying as if you never need to open the lid this suggests it will never get emptied. I await their reply. Mike

I am needing to install a new sewage treatment plant/digester and am wondering what choice I have. I am aware of 240v with an air pump, I have also come across a non electric type with worms. Perhaps there is a solar version with a 12V pump? How can I check whether a particular plant is Environment Agency approved. Many more questions but thats all for now. Thanks Mike
