Water Quality Monitoring (River Pledge 4)

Tender description

Modelling / assessment of our current Storm Overflows has established a quantity of 22 high priority locations within the Northumbrian Water Limited (NWL) operating region which also includes two main cluster locations (urban and rural) with a current estimate of circa 27 actual monitoring solution deployments considering clustering opportunities. NWL require the provision of a turn-key service to provide SONDE measuring devices, deployment, installation, monitoring, calibration and data collection at these locations. Lot 1: Northumbrian Water have committed to implement Water Quality monitoring at our highest priority Storm Overflow locations by 2025 to deliver River Pledge 4 contributing zero pollutions from our assets and operations. Delivery of this non statutory River Pledge will consider the Environment Act 2021 section 82 duties for River Water Quality monitoring - an obligation that must be fulfilled by 2035 through PR24 and PR29 WINEP (Water Industry National Environment Programme). Based upon its current guidance NWL are seeking deployment of either a suitcase or kiosk monitoring solution being located up and down stream of our prioritized Storm Overflows. Knowledge and experience gained through the delivery of River Pledge 4 will strategically inform the business on Defra guidance regarding the WINEP River Water Quality Monitoring delivery programme throughout AMP8 and AMP9 periods.

NWL require the provision of a turn-key service to provide SONDE measuring devices, deployment, installation, monitoring, calibration and data collection at these locations. Scope of services to be procured are as follows but not limited to: Water Quality Monitoring Solution options: The primary deployment solution will be based upon a SONDE measuring those determinants outlined within the current WINEP WQ (Water Quality) Monitoring obligation. The SONDEs must be able to meet the key criteria outlined in current published guidance. Deployment options: o Suitcase - This option could be powered by solar and or battery and is implemented when there is no direct/easy access to fixed generation. o Kiosk - A fixed option that will be fitted in a cabinet style and can be powered using a power source from a NWL owned asset, solar option and or fuel cell. This is the preferred option for locations with access to fixed generation. The framework value is envisaged to be between £600,000 - £1,000,000
