Continuous River Monitoring

Tender description

Water companies have a duty under Section 82 of the Enviroment Act to protect the environment from the effects of discharges from storm overflows and wastewater treatment works. Water companies are required to monitor the quality of water potentially affected by, upstream and downstream, discharges from these assets. This requires the monitoring of the following perameters: (a) levels of dissolved oxygen, (b) temperature and pH values, (c) turbidity, (d) levels of ammonia, and (e) anything else specified in regulations made by the Secretary of State. These measuremnts will typically be made in rivers and/or a local measurement kiosk and we would request evidence for the equipment operating in such an environment both during routine operation and under exceptional conditions such as storms. 3rd party validation of sensor monitoring technology would be of interest at this stage. The application also requires the functionality to achieve the following: - Continuously monitor and log data (every 15 minutes) - Provide a telemetry interface and a public facing portal which can display values in near real time and provide reporting capabilities Unitied Utilities operate approximately 2300 Combined Sewer Overflows and 575 Waste Water Treatment works which are impacted by this new requirement. Unitied Utilities are looking for indicative costs, per installation, based on the following procurement routes: - Supply of instrumentation - Design, build and instalation of instrumentation sampling kiosks - Service and maintenance of the above - Provision, management and administration of telemetry and a web based portal for the above Instrumentation and the monitoring arrangement shall be suitable for monitoring the required parameters in an appropriate range for the application. Solutions may be based on multi-parameter sondes, wet chemistry analysers or a combination of both.
