Anyone know how surface water house drains were commonly done in 1991?
Scenario:
Detached house built that year, location England.
4 downpipes from gutters – one at each corner down to gully traps in the ground and then off to who knows where….
Architect drawings show surface water is to be taken to two soakaways on either side of house out in garden.
However the water company’s records say the property is connected to the public surface water drains and the property has been charged waste water rates on this basis.
Who knows what was actually done and which is correct….
There are no visible manholes other than those for the foul sewer drains from kitchen/bathroom/cloakroom etc and these have all been opened and checked for flow. Two manholes in road close to each other at a nearby corner so both foul and surface water public sewers clearly exist.
I’m familiar with soakaways (mostly in much older houses) but not for piped out surface water.
Would all the pipes from the 4 corners be joined invisibly somewhere or would there be a interceptor chamber/manhole(s) hidden inches (or feet!) below current ground level somewhere at the join(s) before a single pipe goes out to the street: as indeed the foul water drains from the house do?
I appreciate there is a difference between what should have been done and what might actually have been done
Is there any likelihood that the local council building regulations records would have any notes/plans?
