The District’s water distribution pipeline system has approximately 8,000 gate valves which allow damaged/leaking water mains to be isolated while repair work is being performed. These valves must be routinely exercised in order to prevent them from corroding and seizing, rendering them unable to serve their purpose. Even with routine exercising, some valves eventually seize and need to be replaced.
There are approximately 105 inoperable or broken valves in the District’s distribution system which the District plans to replace using a combination of in-house and contracted labor. Working from a prioritized list, 40 valves will be selected for replacement in each of the next two years.
