Wastewater Pipelines, Tunnels & Shafts

Shieldhall UIDs: Holmbank Ave – Pollockshaws

The existing CSO chamber was a brick arched chamber without screening or solids separation capability. Continuation flows from ground-level, egg-shaped, brick penstocks were collected by the chamber before dropping into the 1500mm brick trunk main some 10m below. Storm flows emerged from this 1500mm trunk main, spilled through the unscreened CSO and contaminated the, high amenity, White Cart Water.

This D&B Project was to replace the existing, unscreened, brick CSO chamber with a new pre-cast concrete chamber – incorporating a powered screen – collect the surface water from around the adjacent new-build flats and replace the outfall pipe to the river.
