#FixALeakWeek: The Dedham-Westwood Water District sometimes has leaks to fix, too! The District uses several means and methods to detect leaks within its water system, some examples include:
• Hydrant Sensors: Sensors are permanently affixed to fire hydrants. They work by sensing vibrations in the underground pipe network at night, when water consumption is at its lowest. The District uploads device data monthly to an AI platform that automatically compares vibrations across multiple locations to pinpoint suspected leak locations.
• Leak Detection: Annually, the District hires a leak detection contractor to conduct a survey of the entire water system. The contractor uses specialized acoustic listening devices on fire hydrants and water main valves to detect potential leaks that may not be visible.
• Supervisory Control and Data Acquisition (SCADA) System: A SCADA system is utilized at both our water treatment plants to provide real-time, centralized monitoring and automated control of processes like filtration, chemical dosing, storage tank levels, and pumping rates. This information can be used to monitor sudden events such as changes in pressure, flow, or tank levels, which can be indicative of a leak.
• District Field Staff, Residents, and Commuters: Are our eyes and ears on the ground. If you see water bubbling up on the ground, please notify the District by calling 781-329-7090.
