Summary
This case study outlines a project led by Sulzer's field service teams aimed at reducing combined sewer overflows (CSOs) for a UK water utility. The utility faced significant challenges due to environmental pollution and sought a faster, cost-effective solution to enhance flood water storage. The project involved the installation of circular steel tanks, pumps, valves, and automated controls across multiple sites. Sulzer was initially contracted to supply pumps but expanded its role to include the installation and commissioning of all mechanical and electrical components. The utility benefited from customized pump control panels designed for long-term reliability and future automation capabilities. By the end of 2025, Sulzer's teams had completed installations at 78 sites, with plans for further expansion. The case study highlights the project's success and the utility's proactive approach to improving CSO systems ahead of budget availability for AMP 8. Sulzer has been awarded a contract for a second phase involving an additional 90 sites.
