United Utilities launches tender for Only Rainwater into Windermere Design and Integration Partner

United Utilities is procuring a single Design and Integration Partner to lead the development and consenting phase of the Only Rainwater into Windermere infrastructure programme.

BuzzBaboon Signal Fact

United Utilities Water Limited has issued a procurement notice to appoint a single Design and Integration Partner for the Only Rainwater into Windermere programme. The initiative aims to remove discharges from public and private sources, manage highway runoff, and deliver resilient wastewater infrastructure through workstreams including First Time Sewerage, First Time Treatment, nature-based surface water management, and tunnels, sewers, and rising mains. The infrastructure is anticipated to be promoted through a Development Consent Order as a Nationally Significant Infrastructure Project subject to Section 35 approval by Defra. The appointed partner will handle outline design, planning, consents, environmental impact assessments, stakeholder engagement, site investigations, and early contractor involvement.

Why this may matter BuzzBaboon Insight

Suppliers offering design, integration, planning, and environmental services may find substantial commercial opportunities supporting the single appointed Design and Integration Partner across the feasibility, outline design, and potential delivery phases. The programme structure indicates extensive subcontracting and integration pathways across multiple engineering and environmental workstreams. Bidders may need to align with the overarching goals of achieving the target end state and preparing for upcoming price review and environmental reporting requirements.
