United Utilities Water Ltd (UU) proposes to deliver a programme titled Only Rainwater into Windermere (ORiW), with the ambition to make Windermere the cleanest lake in England by removing discharges from both public and private sources, while also addressing highway runoff. This is a long-term, transformational programme designed to protect the lake's ecology, water quality and amenity value for future generations. The target end state is "Only Rainwater into Windermere", restoring the lake as close as possible to its natural condition and reducing the risk of harmful algal blooms. The programme will deliver resilient wastewater infrastructure that supports communities, businesses and the wider National Park, while creating a potential blueprint for freshwater restoration across England. A coalition has been established to develop and deliver the ORiW feasibility phase. It brings together key stakeholders, including UU, local authorities, regulators and environmental organisations, to provide strategic direction and has sponsored the commission of a ‘feasibility study’ to ascertain the art of the possible for achieving ORiW. Through the commission there are now feasible options for achieving the ambition, to improve water quality, and enhance the environmental resilience of the Windermere catchment, through a proposed ORiW system and wider infrastructure. The proposed ORiW system is made up of multiple workstreams; • First Time Sewerage (FTS), connecting properties to the public sewer network that are currently outside of the network and have never previously been connected to it. • First time Treatment (FTT), for the sites where FTS is not possible, a remote treatment solution will be implemented. • Reduced weather dependent flow, surface water management and management and treatment of highways runoff through the use of nature- based solutions where possible across the catchment. • Construction of tunnel and rising mains. • Upgrade of an existing wastewater treatment works and discharge point. UU anticipates that the ORiW system and the other strategic wastewater transfer and treatment infrastructure required for the ORiW programme (including the tunnel, rising mains, pumping stations, wastewater treatment facilities, associated drainage works and all ancillary infrastructure), will be promoted through a Development Consent Order (DCO) as a Nationally Significant Infrastructure Project (NSIP), subject to Section 35 approval by Defra. UU will shortly be launching a competitive tendering procedure for the appointment of a Design and Integration Partner (D&IP) who will be responsible for supporting the next phase of this programme, designing the ORiW system, including whole system integration, to achieve the programme vision. UU requires the D&IP to complete feasibility, outline design, constructability and other rela... > [Read full procurement scope and specification on Tenderline](https://tenderline.uk/tenders/pro005166-oriw-design-and-integration-partner-ocds-h6vhtk-078c58) ## Lots (1) ### Lot LOT-0000: Untitled lot - **Lot id:** `LOT-0000` - **Status:** planning - **CPV codes:** 45111250, 70332100, 71000000, 71242000, 71246000, 71310000 - **Delivery regions:** UKD - **Delivery countries in notice:** GB - **Contract Period:** 01/04/2027 to 31/03/2031 - **Renewal published:** yes ## Provenance and Official Sources - **Official Notice:** [Find a Tender notice](/out?url=https%3A%2F%2Fwww.find-tender.service.gov.uk%2FNotice%2F099229-2026) - **Last Source Update:** 2026-10-21T06:52:29.000Z - **This document generated:** 2026-10-22T06:32:04.954Z - **Machine API:** https://tenderline.uk/api/public/tenders/ocds-h6vhtk-078c58
