DOWN PIPE SHOE DRAINS DIRECTLY INTO GARDEN


Postby paul68 » Fri Nov 21, 2008 1:05 pm

I've spotted a house i would like to buy and it has several niggles.

The one i want to ask abour here is to do with the drainage of a series of flat roofs the house has.

It is a bungalow with two flat roof dormers fromt and back. To tje front is also an entrance vestibule, also flat roofed.

The drainage is such that surfaec water enters a gutter on the dormer flat roof, then down a downpipe which exits onto the pitched roof below the dormer

This then falls down the pitched roof onto the flat roof of the vestibule. This then drains into a gutter, down a downpipe and directly onto a gravel area in front of the vestibule.

what concerns me is th fact that it doesnt go to the surface water drainage system.

Does this all seem something of a lashup and possibly damaging, or is it more likely a cheap, yet regular solution to not having to break into the existing surface water system?

thanks for any help.

Not so much of a problem really.
Yes ideally it should go into a gully,but how about fitting a water butt
its cheaper,and you can use the water for your garden, saving on water bills

As long as the ground and gravel does not bridge the DPC, then it should be ok as this ground will get wet anyway when it rains.

Or install a soakaway, you'd install gully run the pipe underground away from the house into a chamber - the water will then soakaway into the surrounding soil. LIke it does now - but away from the house.
