Garden is about 8m wide and from manhole cover to fence is 12m. So not a lot of space to play with.
I think I'm going to be digging up the whole garden at this rate, I have a drive way that sits at the end of the garden but is 1m below garden level with a garage on the far side of that and then the veg patch beyond that. I have a decent size footprint of land but very narrow 110 D250 SE HT 110 USW SOLD RRE HSE Dynamic Gone, wife killed it VOLVO XC60 R Dynamic with some toys Polaris RZR 900XP SOLD |

shame veg patch isint closer!
if driveway is 1m lower your going to be going down that extra 1m in the garden to get below that! Cheers James 110 2012 XS Utility 130 2011 M57 bespoke Camper 90 2010 Hardtop 90 M57 1988 Hardtop |

but the rules say the pipework should be between 200 + 700mm to aid aerobic breakdown. If I go to deep then this won't happen. But then run the risk od surface water. It's a complete pain in the arse 110 D250 SE HT

The idea of a soak away from a septic tank is for it to percolate through the ground , to many people dig them to deep thinking it’s the same as a soak away from your down pipes , I’ve had my own building company for over 35 years and replaced a few soak aways I can tell you
 , if the cost is shared I would consider a small treatment plant if space is tight and you intend living there for many years

How do you expect anything to drain/soak into clay? If you have a ditch that has constant flow speak to EA, provided you tank is a twin tank

This is my issue, I know I have a high clay content but not sure what other options I have without spending huge. I could go treatment plant but the bloke who looked initialy at my issue said they were upwards of £10K, but surely I still have the water problem to deal with? Where does that go? Can it just go to surface and down the drains in the road next to the house?
I have no constant flow water anywhere near us and i have a septic tank that looks like an onion. A big ball with a short vertical section caped with a manhole cover 110 D250 SE HT 110 USW SOLD RRE HSE Dynamic Gone, wife killed it VOLVO XC60 R Dynamic with some toys Polaris RZR 900XP SOLD |

I didnt think you could replace cesspits now? I know you cant install new ones, you have to use treatment plants. Soak aways and clay soil dont work well. James

You need some professional advice.
We used to have a septic tank with a soak way - same design as yours. 8 years ago we upgraded to a klargester & it was about 6k all in - fitted it ourselves.It will service 35 people. It services our house & 4 cabins each sleeping 8 people,4 showers,4 loos & 2 kitchens. There are also tables produced by EA (istr) which tell you how big a unit you require depending on household/type of business etc. £10 k sounds a bit rich. I would go to your local supplier of waste treatment plants & explain the problem; klargester through my supplier sent their tech guy to advise. You may need to do a soak test (google this) basically dig a hole & fill with water and time how long it takes to go away. The pipe you refer to is covered in a one way permeable membrane known as Terram or Geotech. Buy the white one not the other sort.Also use drainage stone & also cover that with terram. Just my twopence worth. Guy May your life be like toilet paper ; long & useful. |

The law has either just changed or is due to change shortly. Get some advice regarding that nearby stream as there are much stricter limits regarding nearby water now.
As others have said, it's going to be either a cesspit (cheap to install, expensive to maintain as emptied frequently) or a modern treatment plant (expensive to install, cheaper to maintain as emptied less frequently). Before you commit to a treatment plant, find out how noisy it is. Ours has an air blower that help the aerobic stuff do it's job. Makes an annoying hum. Now in a soundproof box, but still just about noticeable. |

Our installer warned us to keep away from Klargester. He said they used to be great but now use a lot of plastic in the mechanical bits. He was concerned about them wearing out. No idea if others would agree.
He liked Falcon but if we did it again, I'd try and find something without an air pump. |

Was just showing these as an example, certain ones you still need a soak away but reduced by 20% ish

We have just had the same issue with our septic tank and the law now requires us to fit a packaged treatment plant. As we have clay subsoil which would never pass a porosity test we had to apply to the EA to drain using a seasonal soak away and ditch. There are permitted rights to drain if you can prove porosity or have a water course, but not if you have neither. I had to make a full EA application.
We also had to make planning and building reg applications. |
