The upper part of a cylindrical container with an adjustable hollow cylindrical float immersed in it serves as a water level setter in the storage tank of the well. The well also contains a discharge tank, the lowered part of the bottom of which is adjacent to the end of the head of the discharge pipe (12) towards the open channel. An opening (25) is made in the wall of the lowered part of the water intake tank, connected by means of a pipeline (26) with draining storage water receivers (27). Storage water intakes are connected to the holes (28) of the sections of the supply collector sections at the locations of the drains (1). When installing filter storage water intakes, a backfill made of waterproof materials was used (29).
