Protecting a 125-year-old Wearside water asset
Project Overview
CSC Services delivered a comprehensive refurbishment package within Downhill Service Reservoir. Built in 1898-99, the covered masonry structure remains a strategically important part of the Wearside drinking-water network.
The challenge
Delivery combined confined-space working, potable-water hygiene controls and the conservation of original sandstone masonry and flag flooring, utilising Flexcrete 844. Careful selection of Regulation 31-compliant materials was essential.
Scope of works
- Reseal access and valve hatches
- Treat roof, wall and floor-joint ingress
- Repair cracks and redundant fixings
- Recoat internal pipework
- Install stainless-steel valve spindles
- Replace baffle-curtain brackets
- Renew hatch-upstand membranes
- Final clean, flood test and handback
Our approach
Works were sequenced around controlled access and treated-water hygiene requirements. Original joints and defects were prepared and repaired using compatible systems, while internal metalwork was renewed or recoated with materials suitable for potable-water contact.
Outcome
The programme addressed key ingress and water-quality risks, upgraded critical fittings and prepared the compartment for final flood testing, inspection and handback – helping extend the service life of this historic asset.
