## Description
Section 82 of the Environment Act 2021 requires sewerage undertakers, operating wholly or mainly in England, to continuously monitor the quality of the receiving water upstream and downstream of storm overflows and discharges from wastewater treatment works, enabling impact assessment of discharges from these assets on the receiving watercourse. Actions required to meet the requirements of the Section 82 CWQM are contained within statutory drivers under the Water Industry National Environment Programme (WINEP). These duties are phased across AMP8 & AMP9, (2025-2035). 
The objectives of the CWQM programme are to:
- Quantify local water quality impacts from Water and Sewage Company (WaSC) assets.
- Improve stakeholder & public understanding of impacts from the WaSC assets on water quality.
- Inform improvement programmes to meet Storm Overflow Discharge Reduction Plan (SODRP) targets.
- Inform regulatory action.
The draft technical specification requires that monitoring must:
- Be linked to existing regulatory standards; 
- Provide data which can be attributed to the target assets; 
- Provide understandable data to the public; 
- Provide understanding of how performance and water quality impacts of water company assets change over time; and
- Show water quality impacts of water company assets in near real time
By 2035, SWS will be required to demonstrate that at least 75% of storm overflows discharging into or near ‘high priority sites’ cause no local adverse ecological impact. These sites are programmed for monitor installation during AMP8 (2025-2030)   .
DEFRA has published the Interim Technical Standard, setting minimum specifications & performance criteria, to cover the transitionary period prior to development & implementation of a bespoke CWQM MCERTS standard. The interim technical guidance recommends that WaSCs & contracted service providers undertake to develop, and or use, existing standards to establish Quality Management Systems (QMS) covering the following:
- Equipment standards
- Installation standards
- Monitor siting
- Maintenance & calibration
- Data capture, storage, sharing, & validation
Southern Water Services Ltd. is seeking information from all interested suppliers, manufacturers, and solution providers regarding solutions for CWQM, in line with regulatory requirements under Section 82 of the Environment Act 2021 and DEFRA’s CWQM Programme. This RFI aims to gather insights into available technologies, capabilities, and approaches that align with or exceed the interim technical standards outlined below. Responses will inform future procurement and standard development.
We welcome responses from organisations offering complete systems, modular components, relevant services or innovative approaches to monitoring, data management, and assurance. The objective is to understand market capabilities, indicative costs, and technical feasibility for deploying monitoring systems across riverine environments. To enable us to fully understa...
