Continuous Water Quality Monitoring (CWQM)

At United Utilities, it is our commitment to supply great water to homes and businesses, removing and treating wastewater behind the scenes. We are developing our infrastructure in response to climate, population and lifestyle changes so we can deliver a service customers can rely on now and in the future. Section 82 mandates the continuous monitoring of water quality upstream and downstream of storm overflows and wastewater treatment assets, with the objective of improving transparency, compliance, and environmental outcomes. The CWQM programme is a major transformation initiative requiring significant investment in technology, installation capability, ecological and hydrological planning, and real-time data assurance. United Utilities requires a Supplier capable of delivering a robust monitoring solution that integrates with UU’s existing telemetry, data platforms, operational processes, and regulatory reporting frameworks, ensuring accurate monitoring and near-real-time data availability.
