Real-time water quality monitoring in the River Chess

The opportunity is available to provide real-time water quality monitoring equipment to the Chilterns Chalk Streams Project. 

The Chilterns Chalk Streams Project and Chilterns Conservation Board are catchment hosts for the Smarter Water Catchments Initiative developed by Thames Water. A key aspect of this initiative is to monitor changes to water quality arising in the River Chess (a chalk stream) during the ten-year project. An aim of the project is to determine any water quality changes in real-time that arise from operation of the wastewater treatment works at Chesham, and to distinguish these from water quality variations arising from urban runoff upstream of the works. Our intention is to continuously measure (15-mins intervals) water quality upstream and downstream of the wastewater treatment works at two separate locations using multiparameter sondes, and to make these measurements available remotely in real-time (via a website portal) to all project partners including interested local citizens. 

Contact details: kheppell@chilternsaonb.org

Expression of interest window: Friday 18 February  – Friday 18 March 2022
