Yorkshire Water is launching a tender notice of a procurement process for the provision of diffuser system services across its wastewater treatment asset portfolio. The proposed framework will support the assessment, design, supply, installation, commissioning and replacement of diffuser systems within Activated Sludge Plants (ASPs) and associated wastewater treatment processes. The framework is intended to provide end-to-end scheme delivery, including condition assessment of existing assets, design of replacement or new diffuser systems, supply of diffusers and associated mechanical components, installation works, commissioning, performance validation and phased handover to maintain operational continuity. Suppliers with relevant experience and capability are invited to express interest and participate in the CoP.

Award criteria
Commercial Questionnaire (50%)
Quality Questionnaire (50%)
| Item | Category | Quantity |
|---|---|---|
| 1 | Machinery for the treatment of sewage, Sewage treatment works, Sludge-treatment works, Sewage plant equipment, Installation services of electrical and mechanical equipment, Engineering design services, Sewage treatment services | Not published |
Benchmarked against retained Find a Tender procedures with CPV division 42. The category anchor is Machinery for the treatment of sewage (42996000); this is a deliberately broad market comparator. The comparison is shown at several levels rather than pretending one company or region is always the best benchmark.
| Comparison set | Procedures | Reported bids per procedure | Named award suppliers | Price evidence |
|---|---|---|---|---|
| Market: CPV division 42 | 3,019 | 4 median · 51.9 average (1,182 of 3,019 with a bid count) | 5.9 average (1,276 of 3,019 with named award suppliers) | Not published |
| Same buyer | 2 | Not published | Not published | Not published |
| Delivery region: UK | 735 | 11 median · 170.9 average (254 of 735 with a bid count) | 13.3 average (272 of 735 with named award suppliers) | Not published |
| Similar published value (0.5×–2×) | 139 | 2 median · 2 average (1 of 139 with a bid count) | 1 average (1 of 139 with named award suppliers) | Not published |
“Reported bids” is an official aggregate, sometimes reported per lot; it is the closest available competition measure. “Named award suppliers” are winners, not all applicants.
Not enough comparable procedures currently publish both a GBP tender value and a usable lowest-valid-bid value to calculate a responsible price-reduction benchmark. Tenderline deliberately does not infer a saving from named award suppliers or from missing award values.
No planning milestones published.
No linked framework, prior procurement or reprocurement published.
Diagnostic view. “Not published” means this current release does not provide a value.

"description": "The framework will operate on a multi-supplier basis, with Yorkshire Water awarding call-off contracts in accordance with the procedures set out in the Framework Agreement. Prices for call-offs will be determined using the pricing schedules established at tender, with the ability to confirm or adjust pricing where permitted by the call-off process.\nCall-off contracts may be awarded either directly, where the framework provides an objective method to identify the most suitable supplier for a defined requirement, or following a further competition among the suppliers appointed to the framework. \nYorkshire Water will apply the framework rules consistently to ensure transparency, fairness and proportionality in allocating work, while enabling flexibility to meet programme needs. The operation of the framework will be governed by the terms of the Framework Agreement and the procedures communicated during the procurement process."
