putting in a new Fosse septique

Hello from a fairly new member.

Please can anyone help me find out about putting in a fosse, within 35 meters of a water course? The house we have just bought has an old "brown water" system, and so of course our first job is to get a fosse sorted out. The garden is about an acre, but it is bounded by a stream, and anywhere we put the fosse will be within 35 meters of the stream. We have been told that there are extra requirements for the drainage - does anyone know about this? Or can anyone point me in the right direction to find out about these requirements? We are hoping to have all the information we need before we go back at Easter. Also, does anyone know a builder who might be able to do the installation for us? We are in 16, just outside Chalais.

Thanks in advance

Pat

Can't help with your area, but you have 2 obvious sources of information; A fosse installer (lots speak English if this is an issue) or SPANC, contactable via your Mairie. The regs are very tight, so don't assume that one can install a fosse in all cases.

hi ok

first of you can put the fosse where you want , it`s the filter system thats the problem , but the directions state for the fiter system " if within 35mtrs of a WELL the sand filter must be in a bag " other than that you are ok ,you run the outlet in to the soil .river .road any way

I can't believe that's the case Dave: most of the bacterial treatment takes place in the sand filter. You would be discharging incompletely treated sewage into a water course that way.
Or have I misread your purpose in upper-casing 'well'?
My new fosse discharges into a sand filter then into a ditch which is ipso facto a water course. I doubt it would have been permitted had I tried to get away with just the fosse.
As long as the OP has room for a sand filter, he'll be OK.

Thanks for the replies.

Gyn-Paul, how big is your sand filter?

Thanks

I seem to remember that the size of the sand filter is governed by the size of the tank.
We have a 4000l tank and a 35m² filter (champ d'épandage).

Thank you for that, Clair

When you say 35m2, do you mean it measures 35m x 35m, or is it 7m x 5m? Did you have it done recently?

It's 7 x 5 m and we had it done in late 2003.

We were advised from begining to end by the SPANC/SATESE, who did the soil samples, the reports and gave us recommendations according to the soil geology. They also came for a site visit during and at the end of the works.
At the time, we were the first people in the area using their services and we did not pay any fees, but my understanding is that the whol process costs about €200 now.
