The Water Division of the Public Works Operations Group provides preventive maintenance for the water system (including flushing the fire hydrants and exercising valves); takes care of repairs to the water system (including meters, valves, fire hydrants, pump stations, storage tanks, and broken water mains); installs service taps and meters, activates and deactivates service, and performs leak checks; maintains system-monitoring devices and extracts samples and performs tests to assure water quality.
In order to reduce costs the division uses AMR which stands for Automatic Meter Reading. Water meters are located in the ground at each property and have an ERT (Encoder-Receiver-Transmitter) on top of the meter lid that facilitates radio reading. Please be careful around the water meter when mowing or doing other lawn maintenance to avoid damaging the equipment. Damaged water meter components are expensive to replace and can result in costly charges to the customer. If you have any questions, please call 624-4500, extension 3.
