CWQM - Continuous Water Quality Monitoring (CWQM)

Water companies have a duty under Section 82 of the Environment 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 parameters: (a) levels of dissolved oxygen, (b) temperature and pH values, (c) turbidity, (d) levels of ammonia, (e) levels of conductivity, and (f) anything else specified in regulations made by the Secretary of State. These measurements 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. Appropriate and independent 3rd party validation of sensor monitoring technology performance would be of interest at this stage. It is expected that the systems will be mounted directly in the river or will required a sample pumping into a kiosk. Such equipment is required. All equipment must have its own power supply, ancillaries and logger/telemetry unit.
