FIELD: oil industry.

SUBSTANCE: claimed invention relates to a system for maintaining reservoir pressure for pumping liquid into formations. The reservoir pressure maintenance system includes a cluster pumping station with a high-pressure pump, connected by an inlet water conduit to a water supply source, and a flow conduit to a block comb, and water conduits to injection wells. The system is additionally equipped with a water conduit-bridge that connects the water conduit of the injection wells with the discharge water conduit of the municipal wastewater treatment plant equipped with an in-line analyser of wastewater pollution from the municipal wastewater treatment plant and a controller. The water conduit-bridge is equipped with a booster pump and a reagent supply dispenser unit. The water conduit-bridge and the discharge water conduit of the city treatment facilities are equipped with valves functionally connected to the controller downstream of the tee connecting them along the flow of pumped wastewater of the city treatment facilities.

EFFECT: increased efficiency of the reservoir pressure maintenance system.
