Drainage into existing rainwater drain.

[The Dude]

I have existing guttering draining into what appears to be dedicated rainwater drains (if I put a hose down the drain and turn it on I can see water flowing under manhole cover. If I run taps or flush toilets then nothing)

 

Can I drain water from new extension into these? They do not appear to be dual use and it would save me the grief of a soakaway in a heavy clay area.

The new extensions guttering or foul/waste water?

This would be rain water only.

A soakaway wouldn’t work anyway.

You can run surface water into surface water drains and foul water into foul water sewers.

 

What are you draining from the extension?

[The Dude]

A soakaway would not work - we piled to 8m and were still bringing up clay.

 

I explained this to building regs but they didn't want to listen.

 

In any case it looks like I have surface water drains for rainwater from extension so am good.
