Influent flow is measured after the bar screens and grit basins process. Magnetic meters only measure liquidity, therefore, influent equals effluent. Influent flow is measured by two new magnetic meters. The Regional Board has reviewed the calculations the Plant staff perform to arrive at effluent.
Various meters track usage of effluent on in-house processes.
Dye tests determine the accuracy of the meter being tested and a certificate is issued stating the test conclusion. Plant staff informed the Regional Board of how effluent is calculated. Plant staff monitor flow trends which are generated by the computer system that monitors the entire Plant. Magnetic meters are re-calibrated based on a preventative maintenance schedule. Portable meters can be utilized if meters in place are not working properly.
