Running water, electric and soil pipe in same trench

[nh26302]

Hi,

 

I am planning to build an outhouse at the rear of my garden. I will be having a trench dug to run a soil pipe from the outbuilding to the man hole, which is about 40m away. The trench will be dug close to a meter deep in order to achieve a decent fall for the soil pipe. I also need to run an armoured cable and cold water pipe to the outbuilding and was wondering whether all 3 (soil, electric and water) could be run using the same trench, rather than digging a separate trench for the soil pipe?

 

Thanks in advance

There is a protocol for where they sit in the trench so that they are accessible if necessary, and for safety.

if I remember rightly, water goes below electricity for safety reasons.

the waste pipe has to be to the levels that flow, and the bendy services fit around.

Haven't time to find the standard trench layout at present, but I think you basically dig a bit wider, and put elec 100 above water in separate line to the drain.

water min 750mm, electric 400mm, soil is what it is.
