Sewage Management

The sewage management system consists of three stages. First sewage from the main sewer is channelled to a settling tank. The sewage remains in the tank to precipitate. After a while, the undecayed solids are left at the bottom of the tank, and then the polluted water is distributed to the pump house. The pump house then pumps the polluted water to the sprinkler bed. The sprinkler bed is a filter of stones and microorganisms, surrounded with brick work on its outer part, and on top of the filter are rotating arms. Polluted water is pumped to the top of the sprinkler bed, creating jets of polluted water in the air, which then fell to the filter inside the sprinkler bed. The polluted water was here purified. The the purified water was flown to the river.
