Water is distributed to customers through a network of water supply zones. Water reservoirs are located in high points in each water supply zone. Water is distributed from the reservoir across the zone using a gravity system. Water pressure varies at different locations in the zone depending on your property’s elevation and proximity to the reservoir.

Properties in low areas receive higher water pressure. Properties in high areas receive lower water pressure.
