So today I started the main trench that carries the services from the entrance to the Car Park and from there to the main house and Abri/Workshop area. Only got as far as joining on to the first trench I did yesterday but was then able to lay the main incoming water mains in its protective conduit for the entrance to the Car park.
They tell me normally you pull them through but I was not confident so pushed the tube into its protective conduit in advance to make sure. It was not easy.
