Garden City Park Water District has approximately 1,550 isolation valves within the distribution service area ranging from 4 to 16 inches. Valves are used to isolate water main breaks and facilitate the water department’s quick response to any distribution system emergencies that occur. We are continuously conducting a comprehensive valve maintenance program of inspecting, exercising and replacement of valves. This program will help us avoid potentially serious problems when the need to use a valve arises.
