## Summary

United Utilities Water Limited is exploring innovative solids-separation technology for wastewater treatment. The requirement concerns equipment and associated treatment applications that remove suspended solids from wastewater streams using centrifugal, cyclonic or vortex-based separation principles. Proposed solutions should operate without conventional filtration media, membranes, cloth filters or similar physical filtration barriers. The relevant work is wastewater and sewage treatment, including sludge-processing equipment and sewage plant equipment, with applications in the United Kingdom. This is a utility-sector requirement and is classed primarily as goods, although the intended use is within wastewater treatment operations. Suppliers with technologies that can be deployed in sewage-treatment environments, rather than general industrial separation products without a wastewater application, are the most relevant audience.

This procurement is at the planning stage and is currently a preliminary market-engagement exercise, not an invitation to tender. United Utilities expects to gather supplier information before deciding how to proceed. Suppliers wishing to respond to the engagement are expected to request the question set, with responses sought by 6 October 2026. The planned lot has an indicative contract period from 1 December 2026 to 1 December 2027. The buyer has identified the procurement as a below-threshold utilities requirement and has not set out an expected procedure, tender method, award basis or contract value at this stage. The process therefore concerns early market consultation rather than a bid that businesses can submit now.

This engagement will suit technology developers, equipment manufacturers, wastewater-treatment specialists and engineering businesses able to demonstrate practical solids separation using centrifugal, cyclonic or vortex principles. It may also suit smaller businesses: the planned lot is identified as suitable for SMEs. Strong candidates are likely to have technology that avoids disposable or replaceable filtration barriers and can address suspended solids in real sewage or wastewater streams. Relevant preparation would include evidence of technical performance, operating conditions, integration with sewage-plant equipment, maintenance requirements, scalability and compliance with utility-sector operational standards. Businesses with pilot, demonstration or deployment experience in wastewater treatment should be well placed to explain the benefits and limitations of their approach during the market engagement.

## Notice

United Utilities is seeking information from suppliers offering innovative solids separation technologies for wastewater treatment applications. We are particularly interested in solutions that use centrifugal, cyclonic or vortex-based separation principles to remove suspended solids from wastewater streams without reliance on conventional filtration media, membranes, cloth filters or similar physical filtration barriers.
