The water reservoirs of the Regional Water System provide storage for treated water before it is conveyed throughout the municipal distribution system. Water reservoirs must be capable of providing adequate flow and pressure for domestic, commercial and industrial use. They must also store water during periods of low demand, provide water during short power outages and provide a reserve of water for fire suppression and other emergencies.
