I have to dig a new soakaway, so the drive drain I will be installing can go into it.Having read your advice in your pages, I decided to go for the hollow one, rather than a pit filled with hardcore. Having taken your formula, I need a .75cu m soakaway to a 500mm depth.
I asked for for a price for something suitable from my builders merchants, and they have come up with this:

1200mm dia perforated ring 500mm deep C/W step irons Â£104.85ea
1no Ditto as above, but 100mm deep Â£177.82ea

This sounds way over the top, and a bit pricy.
Is there another alternative and could you suggest a stockist near me (hemel hempstead)

Since this will be going under block paving, I felt that a rubble pit may sink over time, and cause the drive to subside.
Also, What sort of cover does this type of soakaway have, and if it doesnt need access(as a rubble pit wouldn't), can I block over the top of it?

I welcome your views!

Use a Stormwater Storage Cell System, summat like the PolyStorm cell.

I've just priced these for another job and they're around 50 quid a piece and measure 1000mm x 500mm x 400mm, so that's only 0.2mÂ³ per unit. You should be able to get a discount for buying more than a couple of units: I was told they could be had for 100 quid per cubic metre when bought "in quantity", although the numpty on the desk wasn't sure just what 'quantity' counted as 'quantity'.

Here's an image I've nicked from the PolyPipe website that should make it a bit clearer. (Actually, I have a long-standing agreement with Polypipe to use their images on the website)

...the big advantage of these systems is they are so easy to handle and install and you don't need to worry about a biscuit and cover, so although they might seem a bit pricey at first glance, by the time you work out the full installation cost, they're considerably cheaper than using ring-sections or owt else.
