The invention relates to septic tanks, stormwater, water supply and other devices designed to exhaust or intake rainwater, and can be applied in communities to reduce the inflow of storm water from urban areas in the underground sewers storm sewers. Disposal of the collected rainwater is accompanied by the production of electricity directed to the production of oxidant-bactericide is sodium hypochlorite (NaClO). Collected and purified effluent is used for sprinkler systems, irrigation and other household-level requirements for water quality. The use of such devices, in addition, prevents the gradual destruction of the basement and Foundation of buildings located in urban areas.

Known network of storm water drainage and meltwater, which is an element of a complete separate Sewerage system, consisting of water wells, drainage pipes and water treatment plant surface runoff (Yakovlev S.V., ravens J.V. Sewerage and wastewater treatment / Textbook for universities: - M: ASV, 2002, p.17, 1.5, b).

This network collects and cleaning of storm water and snowmelt runoff, dumping it in the water, but does not provide its operational use in economic the e needs excluding savings of potable water, which is largely used for irrigation and other economic needs.

The closest technical solution is the patent of the Russian Federation No. 2347039. "Device removal and disposal of storm and snowmelt runoff", bull. No. 5, published. 20.02.2009,
