FOSSE v MICROSTATION

Post by Izzyedwards on Sat Nov 16, 2013 12:14 pm

Hello Folks - could do with a bit of advice please.

Unsurprisingly, the fosse at our cottage doesn't conform. Had a nice lady out from NCA yesterday to do a survey for us to get a new fosse put in. Now, apparently our soil / land is of a type (clay I'm guessing) where the water from the filtration bed won't soak away, so we'll have to pipe the clean water all the way round 3 or 4 fields to get it out. Which we'll apparently have to pay for, even assuming the Maire agrees....
She mentioned in passing that if all else fails we can install a microstation, which I knew nothing about. Having had a stroll through the internet today, I understand how such a thing works, but my question is, will we still have to pipe the clean water away once it comes out of the microstation, or does this work in a different way? We had set aside a budget for the fosse, which I reckon will be comparable to getting a microstation installed, but it's this huge run of additional piping that really concerns me from a financial point of view.....

Any advice or experiences would be gratefully received.. Many thanks

The outflow still has to go somewhere... typically, piped into the nearest ditch/stream. I have also heard of people tanking the output, and using it drip-fed onto the garden as needed; also, just piping it into a gravel filled soakaway, although if you're on clay that might not work awfully well. It's all going to depend on what your local SPANC gal/guy (or whoever) will allow, and the physical circumstances of your land.

As and when they catch up with their backlog, we will undoubtedly be facing the same questions with respect to our completely non-conforming system. I have a preference for the micro-station approach, and have wondered if I could pipe the outflow through a reed-bed (although we do have a tiny stream a few hundred metres away at the boundary of our land). Whilst the purification provided by the reed bed is obviously not necessary with a micro-station, it would be a neat way of dealing with the outflow.

I suppose that's not much help; I'm as interested as you are in any clearer answers!

Hi Tofu_lover - hmmm, that's what I thought. I have emailed the nice NCA lady to ask whether the Microstation option would solve the problem of having to pipe the water away.. I think the problem is that we are surrounded by fields, and as far as I know the nearest moving watercourse to us is a good half a mile away at the river.. And I will have to pay to put in pipework to get the outflow there... Gawd knows how we'll be able to afford it Shocked I did wonder about tanking it to use in the garden, so will try to explore that further.

There is already a problem with rainwater drainage on our lane - if there's a heavy downpour it just creates a torrent in the lane and if we're really unlucky it comes racing through our and our neighbours front yards and into the house! But that's another story..

Anyway, I'll let you know if I find anything else out..

Hello Amber - it's this lot http://www.nca-env.fr/ The Maire told me I needed to get a survey done by them to specify the technicalities of any new fosse I needed to install. The lady who came out was very helpful, so we'll see what she comes up with.

Is this a new idea then, as that link seems to indicate that company are privately run, rather than a Government agency as SPANC who, I thought, could advise you on your fosse. I'm very surprised that it's been suggested you can't have a sand bed filter from your fosse; we are on clay and when it rains really hard we get wonderful puddles (more like mini lakes!) but we were told a sand filter system would not be a problem and it hasn't been. We couldn't have the run off pipe system as our ground runs uphill away from the house. The only stipulation for us was that we must not use our well water for human consumption as it's not 30 metres away from the filtration bed.

If you are interested there are photos of the istallation (about three years ago) of our fosse here:

P.S. We were advised by the installer to get good photos of the marks on the fosse and the piping, just in case there was ever a query about what had been installed!

I have no idea if the use of NCA is a new thing Amber - we've only been living here a few weeks, and I asked at the Maire what I needed to do and that's what they advised me? Interesting however that your soil doesn't present a problem with a conventional fosse, so thanks for that... I'll see what the survey says when it arrives..

Hi Izzyedwards
We had a letter from our local SPANC, arranging for an official to visit us. When the fella from SPANC arrived he wanted to see our Fosse docs, asked for doc's giving details of when it had been emptied. He then inspected the system and completed our form, he said approval would follow by post, which it did.
I have never heard of these other people and would contact your local SPANC office before you go any further as it sounds suspect to me. As regards your fosse outfall system,Ours runs into our compost heap and was A'ok by Spanc as it did not leave our land. We also had a bumper crop of melons,cucumbers,pumpkins,peppers and chillies off the compost heap this year. So get Spanc in before you sign anything or agree any works. SPANC would have to agree any system or works anyway.

Ok Simmo thanks. I'll wait and see what this NCA lot come up with and then double check with SPANC. I'll also maybe go back to the Marie and see what the relationship is between NCA and SPANC, and why they told me to contact NCA in the first instance.

Hi Izzyedwards
You do right, Some Maries put work the way of friends and local firms so it's always best to check with the horses mouth so to speak. I will always remember the young lady from SPANC saying,  hello I'm from SPANC I'm arranging to come to do the checks. Well i nearly fell of my chair till i had put my brain into gear and translated the message properly.They then sent a young fella and it spoilt me whole day.

HEH!! You should be so lucky Simmo! Mind you, my other half was quite taken with the petite blonde surveyor lady who turned up from NCA...
