Water Distribution System

Water Meter PitA distribution system consists of a network of pipes, valves, fire hydrants, service lines, meters, and pumping stations. The system delivers water to homes, businesses, and industries for drinking and other uses. The water is also used for fire protection.

The network of pipes, pumping stations, and service storage reservoirs must have sufficient capacity to meet maximum water demands plus fire fighting requirements and still maintain adequate water quality and water pressure throughout the distribution system. Valves are necessary to isolate portions of the distribution system for cleaning, maintenance, repairs, and making additions to the system.

The distribution system should be free of cross-connections with unapproved water supplies, which could allow contamination to be introduced into the system.

  1. Place barricades, signs, and traffic cones around work sites to protect operators and public.

  12. Safely load and unload chlorine cylinders and other dry and liquid chemicals.
