URBAN WATER SUPPLY SYSTEM Russian patent published in 2008 - IPC E03B7/04 

FIELD: construction, particularly water supply systems for built-up areas.

SUBSTANCE: water supply system comprises circled water-supply net divided into zones communicated with each other through water delivery means, water supply sources to deliver water to the net, pumping plants corresponding to each zone, as well as pumping plant with inlet and outlet pipelines. Pumping plants corresponding to each zone include a number low-lift and high-lift pump sets connected in parallels. High-lift pump sets supply water directly to consumers of said zone. Low-lift pump sets deliver water to supplementary booster pumping plants adapted to provide consumers with water. At least one pumping plant corresponding to one zone may include a number low-lift and high-lift pump sets connected in parallels and provided with pressure pipelines, as well as additional low-lift pumps with pressure pipelines. Additional low-lift pumps supply water to supplementary booster pumping plant.

EFFECT: decreased costs of system incorporation.
