drainage help

Postby kilmo » Thu Jan 05, 2012 9:49 pm

hi im currently completing the plans for a change of use of my property down stairs from a pub to a dwelling, the one issue im stuck on is drainage, i have attached a sketch showing the existing drains in black and 2 posible routes in yellow and purple.

the length of the yellow / purple routes are 8-9m each
in the kitchen area there will be a dishwasher and sink
in the utility room washing machine and sink.

the floor is solid concrete.

any suggestions/input would be welcome.
my plans will have to pass building regs approval

Simply Build It

the existing manholes are no use whatsoever. Where the main drain is in yellow,and your drain connects to, you need to install a manhole about 1 metre inside your boundry.So that your drain has a clear straight run to the manhole,Not around the property,The Building inspector may also insist you have an internal screwdown air tight manhole.
