See above, as its four trenches of 11.5m

 

Should have been finished is weekend but due to heavy rains we are having to redo some the work

 

Closed loop drainfield hence the fall is still applicable....

 

Right, outside to shovel another few tonnes

There is no standard length for any size house I'm afraid figgy, the length of any soakaway/ leakage field is determined by the results of percolation tests. I questioned the 11.5mtrs as on a septic this would be rarely sufficient for any drainage to have any longevity, unless you had extreme drainage in the area required, nothing I've ever come across.

My figure of 100mtrs was plucked out of the air to highlight that if you kept a trench level and use the aggregate to create fall then by the time you got to 100mtrs (can't be bothered to do the math) you'd have negative shingle in the trench based on the falls required for 'most' drainage situations.

This is what I was told off a few sources as the norm for average house with three to four occupants, due to fats oils and salts in the water, mainly bath water as fat traps catch the kitchen grease and fat. Any less and you don't get long enough out of your soak away due to bonding in the substrate.

 

I ended up going for a sewage pumping station into the main sewage drain.

I only know one domestic house that has a fat trap, and thats Mr Camerons

No mate, someones led you up a merry path by the sound of it and bull poo does baffle brains - there is no standard length. Sounds like you've been sold a pump station, drainage in & out, electrics, control panel, float switches, plus the connection fee to main sewer - was he's Mr Turpin

Stops you biting your finger nails!!

Problem I had was the ground is solid clay that had some land drains because it holds water. Only missed getting into the sewer main by 500mm. When I looked Into getting a klargester system it was deemed I would need the above 100meters of foamed pipe for drainage and would be lucky to get a couple of years out of it before having to reroute it,not enough land for this so a pumping station was installed instead. A few of the neighbours are using them too.

 

Even if I could have used a septic system was told must use a fat trap or it will clog and not work,after seeing the fat in the pumping station I can believe it.

 

Have used klargesters in the distant past but had a outlet into a soak away field,how regs have changed since.
