I’ve recently bought a house and am researching the choices for a fosse septic and filter beds/treatment – currently we have nothing and I am keen to get this rectified quickly. The more I read the more confused I get. I do have an appointment with SPANC but I would like to understand things more prior to their visit.
A couple of questions please which I would appreciate advice/thoughts on:
- On the guidance (fiche d’aide au choix) which comes with the Demande D’Installation form it seems to indicate (if my translation is correct) that a micro-station requires more maintenance (e.g. in terms of emptying) than if you use the other treatment options such as a soakaway (tranchees d’epandage). However, general research into microstations talks about them needing less maintenance than conventional approaches. Does anyone have any thoughts on this and the pro/cons of micro-stations please?
- Does anyone have any experience/thoughts on the Bionut system where the waste water is treated through a filter containing hazelnut shells. A company has been recommended to us but they only install this system.
- Does the 35 metre rule only apply if you use a well for drinking water? We are in the process of being connected to the mains so do I not need to worry about the fosse location in relation to the well?
Any other thoughts/advice on the installation of a fosse would be gratefully received, particularly on how to keep costs down.
