FIELD: oil producing industry.
SUBSTANCE: invention relates to engineering ecological support systems and it can be used for elimination of technogenious pollution of ground waters. Proposed system contains submersible electric pump to reduce water level and submersible electric pump to produce oil products. Each pump is connected to separate power switch connected with water level sensor unit and oil product sensor unit, and pump operation control units. System is furnished with electric pump current sensors and units to analyze stability of causes of their switching off whose inputs are connected with outputs of current sensors and outputs, with electric pump operation control units, with possibility of testing as shutting down of electric pumps.
EFFECT: improved efficiency and reliability of system owing to prevention of considerable dynamic loads under transient conditions caused by repeated of pumps after switching off.
