PRO005166 - ORiW - Design and Integration Partner

This notice relates to tender activity for the provision of certain design and integration services, as explained below. United Utilities Water Limited (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 and chemicals. 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. This Scope of Requirements does not include agricultural impacts; these are being considered by other programmes. 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 d
