FIELD: methods or layout of installations for water supply, particularly for plants, which generate thermal energy and electric power with the use of solid fuel, prevention of natural water resource contamination with suspended solids and hazardous chemical compositions. ^ SUBSTANCE: system comprises sewage tank, runoff ditch, filtering dam, reagent preparation and supply station, floccule forming device, floccule distribution device, which distributes floccules over runoff ditch width, water deposit structure, sorption filter and water cleaning complex, which cleans water in winter period. Complex includes ground and sorption chambers and underground pipeline. Above components are arranged in series downstream the filtering dam and arranged below seasonal ground freezing level. Water deposit structure comprises primary and fine cleaning ground chambers. Bases of filtering dam, ground and sorption chambers and underground pipeline are on one level. Floccule forming device is made as multistage zigzag gutter. ^ EFFECT: increased operational efficiency and ecological safety, possibility to use ecologically clear natural materials for system construction. ^ 2 dwg |
