£10m Sewage and water treatment framework open for bids

9th July 2019

Yorkshire Water (YW) has initiated a framework for sewage treatment services worth £10,000,000.


Yorkshire Water manages the collection, treatment and distribution of water in Yorkshire, supplying around 1 240 000 000 litres of drinking water each day. At the same time collecting, treating and disposing of about one billion litres of waste water safely back into the environment.


This framework will support service delivery in maintaining key operational activities. A range of specialist technical services will be selectively employed across YW’s estate to support applications and processes for raw water, treated water, waste water, sewerage treatment and clean and sewer networks. These services are vital to supporting safety and compliance across YW’s business. This directly links to the business commitments and performance measures contained within Yorkshire Water’s business plan. YW is thus establishing a framework for providing/upgrading diffuser systems.


The services will involve:

    • Replacement of existing systems within activated sludge plants where only the diffusers and minimum pipework would be replaced
    • More substantive upgrades of diffusers, below and above water level air pipework, valves and blower configuration

During the course of the contract life the services will support AMP7 delivery period where there will be an expected requirement for around 10 000 000 GBP worth of installations or upgrades to diffuser systems. The current anticipated programme allows for the replacement or upgrade of 64 activated sludge plant lanes, equating to approximately 18 000 diffusers. The contract will be single source with the successful supplier being able to provide all the required services across the entire range of YW’s assets.


The contracts awarded will run for 60 months and can be subject to renewal.


The current deadline for requests to participate in this framework is 31 July 2019.
