Marden Quarry

Contract Value
Whitley Bay, North Shields
Northumbrian Water
Form of Contract

Northumbrian Water has invested £2.5 million to separate Marden Quarry and other sources of surface water from the public sewer network. This will improve the performance of our sewer network and help reduce the risk of
flooding. Marden Quarry, Whitley Bay was the second and final phase of work to be carried out in North Cullercoats.

Esh-Stantec was appointed to carry out the works which involved the separation of Marden Quarry and other sources of surface water from the public sewer network. The scheme involved the installation of a 5m wide and

9m deep shaft and associated underground drainage installed using tunnelling techniques. Marden Quarry acts as an attenuation pond that receives flows

from land and highway drainage upstream, including North Tyneside Hospital. The pond drains into the combined sewer network in Burnside Road.

The contribution of this surface water significantly reduced capacity within the sewer network and increased the risk of flooding within the catchment and also impacted the Sewage Treatment Works at Howdon. Works at Marden Quarry created a new surface water drain to separate out the existing flows from Marden Quarry pond from the combined sewer, therefore increasing the capacity and mitigating the flows from other systems. Works have resulted in improved capacity all round.
