Схема утилизации серых вод в доме

Clean technical system diagram of a residential [greywater recycling system] for toilet flushing, left-to-right flow layout on a pure white background. On the left, [three water sources]: kitchen vegetable washing sink, bathroom wash basin, and washing machine. Each source connects through a diverter valve to either the sewer drain or greywater recycling line. The greywater line routes into a pre-filter module containing a coarse mesh filter, sediment trap, washable cartridge filter, and kitchen grease separator. Next, a low-level greywater collection tank with an inspection cover, high/low water level sensors, and an overflow pipe to the sewer. A transfer pump pumps water upward into a large white plastic storage tank equipped with low, middle, and high level sensors, overflow to sewer, drain outlet, optional UV disinfection module, and ventilation. An outlet pipe feeds the toilet cistern via pump or gravity, accompanied by a backup municipal clean water supply with an air gap and backflow preventer. A central [Raspberry Pi 4 controller] connects via dotted black signal lines to all sensors, solenoid valves, pumps, leak sensor, and alarm. Solid blue arrows indicate water flow, red arrows indicate overflow and emergency drains. Style: modern engineering schematic, crisp vector line art, labeled components, clear directional arrows, highly detailed and legible.
