    Default Teeing in mains to feed a tea cabin.

    Ive been asked to run a mains feed to feed a tea cabin in a courtyard behind a shop. Its on land being leased from the shop which has the mains water supply. They want me to tee into their supply underground and run the new pipe to the new tea cabin. It will involve digging a trench across a 3m wide right of way tarmac access road to a house, packed gravel and soil either side.
    The existing mains supply is about 450 deep. What would be the minimum allowable depth for my supply trench for this purpose. Im thinking the trench only needs to be wide enough to pick down to a suitable depth. If I dug a trench just wide enough to get the pipework down 200mm? Please help, im not sure where to begin.

    750mm depth required, no matter what others have done. Establish position of other utilities and pipe runs. Tarmac, 3 metre wide, can in most cases be thrust bored to avoid disturbance and making good. Provided trench 3 metres long can be dug one side, thrust bore can be simple as scaffold tubes and 14lb hammer.
