ZONED MEGAPOLIS WATER SUPPLY SYSTEM Russian patent published in 2016 - IPC E03B7/04 

FIELD: water supply.

SUBSTANCE: invention relates to water supply. System comprises circular water supply network (1), divided into zones (2 and 3) interconnected by water lines (22), sources (4) power supply network water, areal pump stations (7) with suction pipelines (6), parallel pumps (8) with pressure pipelines (9) connected with pressure main pipelines (10) for supply of water in zone, areal standby-adjusting tank (5) connected to at least one source (4) for supply of network with water and areal pump stations (7) by means of suction pipelines (6) installed at water supply network (1) at least one zone at least one augmenting pump station (11) with suction pipeline (12) installed at water supply network pump station (15) with feed (16) and discharge (17) via pipelines and connected to it non-pressure standby-adjusting tank (18). Non-pressure standby-adjusting tank (18) is connected by supply pipeline (16) with pump station (15) installed on water supply network, at least one augmenting pump station (11) of at least one zone is additionally equipped with pressure pipeline (13) and local water supply network (14). Pressure pipeline (13) is connected with local water supply network (14), and suction pipeline (12) with water supply network (1) of this area. System is additionally equipped with supply pipeline (19) which connects water supply network (1) and non-pressure standby-adjusting tank (18), extra local water supply network (20) connected to supply pipeline (16), bypass line (21), connecting supply pipeline (19) with discharge pipes (17).

EFFECT: reduced power consumption for transportation of water and higher reliability.
