Lyza Posted January 17, 2009 Share Posted January 17, 2009 We have just had out visit from SPANC. We have a tiny stone cottage in Brittany (100years old) with no land and a concrete fosse. I expected that we would be in real difficulties but apart from separating the grey water from the sewage, (at the moment all our water goes into the fosse) directly into the soak away and installing a grease trap through which all the grey water must go before being sent to the soakaway we have been passed.How much does a grease trap cost? Is it hard to install one? How big is it?Very grateful for any help.Lyza Link to comment Share on other sites More sharing options...
AnOther Posted January 17, 2009 Share Posted January 17, 2009 It depends how high tech you want to go. In it's simplest form it is just a small collector through which the kitchen waste water passes separating the grease which naturally floats on the top. Ours is a small, apparently home made, concrete one say 50cm sq x 30cm deep, but I'm sure you must be able to buy them off the shelf quite cheaply.If you wanted to go space age then as an illustration of technology and probably well OTT for your circumstances, something like THIS would do the job, but at a cost, although if you had an indoor one that would be offset to some extent by avoiding the need to dig outside and break into old existing pipework with all the attendant potential for collateral damage.This diagram shows a typical layout.[img]http://www.frenchpropertysearch.com/images/content/4%20stages%20of%20treatment.jpg[/img] Link to comment Share on other sites More sharing options...

Vanman Posted January 28, 2009 Share Posted January 28, 2009 Golly - the Leroy Merlin bac a graisse is 500 litres. That's the same size as our old concrete fosse septique! Link to comment Share on other sites More sharing options...
pachapapa Posted January 28, 2009 Share Posted January 28, 2009 Current installations would have the distribution pipes connected with a second "regard"; the reasons for this are self evident. Link to comment Share on other sites More sharing options...

AnOther Posted October 9, 2009 Share Posted October 9, 2009 Seemed a pretty innocent link to a company website, unless I missed something else. Link to comment Share on other sites More sharing options...
