Hi,
I need a soakaway for a extension that has a roof area of just under 34m2 and it needs to be done to BRE 365 standards.
I was wondering if anyone know who or where I could get the calculation for soakaway size done cheaply (and relatively quickly)?
I have looked at the testing method and I can do that without a problem but the maths calculation is where I could use some help.
Thanks.
