Hello,

I have just moved into a new house that has a badly water logged
garden, due to it being a clay soil.

I have just replaced the boiler which has left me with 2 1m3 cold
water tanks.

My question is, if I bury these tanks upside down in the garden,with
6-12" of soil on top, what area of grden would each tank drain.

i.e. do I place them 4m apart etc.

I will then conect the tanks togethor with a length of drain pipe, and
then connect both to the surface drains of the house with appropriate
pipe work.

I have spoken to my neighbour who says he dug 2 6ft deep pits, and did
not break through the clay soil :-(

Thanks in advance for any advice
