Supply of liquid-phase nitrous oxide (N₂O) monitoring equipment and associated calibration equipment for use at Yorkshire Water wastewater treatment sites. The equipment will provide continuous monitoring of dissolved N₂O concentrations and temperature within activated sludge process lanes and includes sensor probes, controllers, calibration equipment, associated accessories and manufacturer support. Equipment must be supplied directly by the original equipment manufacturer and is required to enable the collection of N₂O monitoring data for baseline establishment and operational performance assessment. The equipment must support continuous data collection, integration with telemetry and control systems, and operation in accordance with Yorkshire Water's specified technical and environmental requirements. Equipment will be supplied to 13 wastewater treatment sites. The quantity of sensors, controllers and associated equipment required will vary by site in accordance with the site-specific design and monitoring requirements. Installation and commissioning will be undertaken by Yorkshire Water, or through a separately contracted delivery partner under an existing framework agreement.

Procurement Act 2023

Direct award This contract is awarded as we engaged the market under a UK2 notice for a managed service but pivoted from the approach due to the need for a direct contract with the manufacturer, offering improved collaboration on potential future developments. Through the market engagement, we confirmed there is a single manufacturer capable of direct supply for liquid phase N2O monitoring devices which have been tested in the UK Water industry.
