Occasionally, a new water district pumping station will be installed in a location that is not served by 3-phase power. The options to run the pumps on 3-phase include (but are not limited to): Pay the electric utility a fee (often prohibitive) to bring 3-phase power to the site. Generate the 3-phase power on-site. To generate 3-phase … Read More →
Ice Storm Preparations When meteorologists are predicting an imminent Winter Ice Storm, it is highly recommended that the Water Utility perform certain preparations to minimize the potential impact to the production and distribution system. Freezing rain and Ice Buildup on Antennas can cause temporary loss of radio telemetry communications. So it is highly recommended that … Read More →
