Tunstead Milton DG5, High Peak

Donegan Civil Engineering were appointed as the main contractor on this United Utilities project.

United Utilities had a requirement within the AMP4 period to provide asset improvements that will remove properties from the DG5 Flooding Register.

During times of heavy rainfall the local combined sewer network would surcharge causing foul sewage to emanate from the gullies flooding local properties and closing Manchester Road.

The scope of works included 110m of 1050mm tank sewer with 85m3 (85,000 litres) storage capacity for combined water, 50m of 375mm and 35m of 225mm opencut pipework along with 9 manhole chambers ranging from 1200-3000mm diameter.

There was also 30m of 225mm augerbore underneath Manchester Road to minimise disruption along the busy rural route with no possible diversion route available.
