Large Soakaway - Couple of quick questions!

[Mulberry View]

I'm hoping to start digging my 20m3 Soakaway this weekend. I'm going for 6m x 3.6m x 0.84m.

 

1. Pea Shingle or Sharp Sand to surround the crates?

2. Geotextile wrap for the crates yes, but should I also provide another separation layer between the backfill layer and the surrounding soil?

 

I'm grateful for you guys, so any help here is appreciated as always.

If using crates follow manufacturer instructions?

I don't have the crates yet, I didn't realise they'll supply this?!

We didn't use crates at all, just slotted 110mm pipe in crushed gravel, geotextile below and above.

 

The pipes were covered with more gravel then geotextile.

That's quite cool. Is it an alternative to a crated soakaway or something completely different?

Crates are really an alternative to what we did. That design just follows the recommended design by SEPA. If you have space its easy and almost no material costs.

Just what we did for our sewage treatment plant
