A 5.5m deep shaft was excavated on site with trench sheets and pump out frames. A 10m long timber heading was then driven to the main sewer to connect 2no 225mm pipes. Due to the small diameter of the existing main, a large pipe could not be installed, hence our proposal to connect two pipes to achieve adequate capacity for the new drainage installation.
