PFAS Catchment Investigations · UK public procurement notice
Authority: SEVERN TRENT WATER LIMITED (Public body)
What is being bought
Published requirement descriptionSevern Trent are looking to understand sources of PFAS in surface water feeding Whitacre and Church Wilne WTW with a view to understand risk at our WTW now and in the future. We are also
keen to explore what is controlling variation and concentrations, and what mitigation actions may help to reduce PFAS levels in these catchments and their potential effectiveness. This information will be used to plan the necessary level of PFAS removal required at water treatment works in these
catchments now and for the future, and work towards less reliance on energy intensive removal / destruction techniques. The work also aims to further develop our stakeholder engagement activity, fulfilling commitments in DWI guidance as well as working with stakeholders to reduce sources in catchment.
The objectives of the work are to:
- To understand where PFAS of concern are originating from considering both current and historic activities in our catchments.
- To understand how PFAS levels may change in the future.
- To understand what is controlling PFAS concentrations.
- To review what mitigation options are available to reduce PFAS levels and how feasible / effective they could be in our catchments and at what cost.
- Support ST's stakeholder engagement activity
- How the procedure runs: Pre-Qualification Questionnaire (PQQ) Stage Interested suppliers will complete a PQQ to demonstrate capability, experience, and compliance with minimum requirements. Evaluation will be based on pass/fail criteria and qualitative responses where applicable. A shortlist of successful suppliers will be invited to the next stage. Request for Proposal (RFP) Stage Shortlisted suppliers will receive the full scope, pricing schedule, and evaluation criteria. Suppliers will submit detailed proposals including technical approach, pricing, and risk management documentation (e.g., RAMS). Initial evaluation will be conducted against published award criteria. Negotiation and Refinement Following initial evaluation, The Utility may enter into negotiations with suppliers to clarify proposals, refine technical solutions, and address any outstanding questions. Final Tender Submission Suppliers will submit a best and final offer (BAFO) incorporating any negotiated refinements. Final evaluation will be conducted using the agreed award criteria.
