Sewage system cleaning
Bottom sludge is accumulation of silt, sand, residues of construction and finishing materials (paint, glue, cement, polyethylene film, painting tools, packaging, etc.). All these reduce the working space of the receiving chamber, affect the duration of the cutting mechanisms and, as a result, stimulates the failure of pumping units. To avoid this, the residue should be cleaned regularly.
How the specialists who brought the cleaning equipment were executing the works? They went down to the bottom of the tanks, the depth of which is from 4 to 6 meters in protective clothing, gas masks and safety belts. First, the bottom residue was removed by a powerful vacuum pump, and then the bottom and walls of the tank were washed with a high-pressure washing machine «Karcher». Two units of special equipment were involved: the first bunkered the bottom sediment, the second – washed out the tank.
However, the sediment should not just be washed, but also taken to the treatment plant. The nearest is in Ovidiopol, where the waste was sent.
Monthly planned prevention of the Sewerage network is carried out by the employees of the water management unit on their own. They check and wash the gravity main collectors, intermediate and receiving wells for connection. They carry out the preventive maintenance of the equipment SPS: float mechanisms, rake compartment, line of agitation of sediments, the controller of control of pumping units, GSM device for monitoring the operation of pumps, wash the walls of tanks. But all this does not prevent the formation of heavy sludge. Therefore, large-scale prevention of the Sewerage system, which was mentioned above, should be carried out once a year.
The “Pine coast” includes:
- 12 sewer pump stations (SPS);
- about 480 units of intermediate and receiving wells with depth from 1,2 m to 4,5 m;
- 11,8 km of the gravity pipeline;
• 11,2 km of the pressure pipeline.
