Regional Water District

The Cowichan Valley Regional Water District operates 17 surface and ground water systems and 2 reclaimed wastewater treatment plants. The district treats the ground water with potassium permanganate to oxidize the high content of manganese and iron in the water. The water is then filtered through green sand filters and industrial bleach is added to the water with a target residual between 0.5 and 0.7 ppm (parts per million).

The district previously used 7 membrane analyzers from Severn Trent Services Capital Control® to monitor the free chlorine residuals. The analyzers experienced drift due to the challenging water conditions and required at least one calibration per month. Calibration of each unit took on average 75 minutes (including driving time), which resulted in 105 operator hours for all seven analyzers per year.

The Cowichan Valley Regional Water District bought the first Krypton® Multi analyzer in 2018 and was impressed with the performance. The unit could be easily installed, started up and was ready to deliver precise readings within one hour. Once the ASR® automatic sensor cleaning schedule was optimized, the sensor did not require any preventative maintenance.

Based on the excellent experience, the Cowichan Valley Regional Water District replaced six Severn Trent Services Capital Control® systems with Krypton® Multi analyzers. The Krypton® Multi analyzers have provided a worry-free maintenance solution and will save about 105 operator hours per year.
