Pulsar Process Measurement (UK) have supplied non-contacting ultrasonic level measurement instruments that have been incorporated into United Utilities flagship project, the Mersey Estuary Pollution Alleviation Scheme (MEPAS), providing key control and monitoring functions throughout the network of CSO/SSO chambers, vortex and interceptor sewers that form the MEPAS network. When the major Sandon Dock Wastewater Treatment Works was expanded during the 1990's, the scheme included a substantial network of interceptor sewers and CSO, designed both to separate out solids and particulates before the main Works and to manage storm surges. Some of Pulsar's earliest equipment was used as the project went live, including the unit that bears the serial number 0001. The Mersey is now so clean that, within a few hundred yards of the sewage treatment works itself, a scuba diving centre is flourishing, and many species of fish have re-established themselves in the river.
