Water management

Engineered protection for critical water infrastructure. Water and wastewater networks operate under constant pressure. From treatment works and pumping stations to below-ground chambers, valve rooms and flood defence structures, every penetration must withstand water, gas, chemical exposure and environmental stresses without deterioration. Failures can lead to contamination, service outages, equipment damage and costly emergency repairs.

“CSD Technical Services delivered the water, and gastight sealing works to a high standard across our control room and DNO substation. Their support contributed effectively to our wider climate action plan, including the installation of a new solar farm and battery storage system. We were very satisfied with the work and will be considering CSD for future projects.”
