FIELD: means to operate underground water intakes, vertical drainage flood-control means, underground water replenishing systems, which replenish water reserves via closed infiltration systems, particularly to regenerate mechanically and biologically mudded water wells.
SUBSTANCE: method involves sealing well at static level depth with the use of pneumatic cap; holding the well as it is for 3-6 months; breaking mechanical mud plug by water well washing; flushing well sump with ejector pump. The ejector pump is hydraulic elevator with washing-out device. Flushing flow rate corresponds to estimated well rate.
EFFECT: decreased material consumption and increased ecological safety.
