Maintenance performed on existing lines and equipment. Numerous safety standards influence the design and construction of the proposed treatment facility. OSHA and local codes should be referred to. Shutoff head occurs when the pressure in a system is higher than the pressure the pump produces. The net result is that no more pressure can be obtained from the system and the pump is ineffective.
Stray voltage causes noise in electrical signals and deterioration of metals.
Suction head is the maximum vertical distance a pump can lift water, no more than 34 feet from the source to the pump. Tanks are large metal containers, which hold water for storage for peak demand and to increase pressure in a system. Cross connection regulations must be considered as well as pressure and flow needs. Telemetry is the ability to send information collected in a real time environment over long distances to be recorded and interpreted for current and future use. Venturi refers to suction created by velocity.
