Organization and performance of work on connecting the drainage water pipeline from the BPS-22 to the K2 industrial storm wastewater system:
- carry out excavation work on excavation (prepare a trench with the necessary reinforcements against a collapse) from the well-pressure damper (KGN) of the drainage systems to the place of the proposed tie-in into the pipeline of the industrial storm sewer K2, between the wells K2-8, and K2- 3. (Mark sewage pipes K2 - polypropylene pipe DU160). Trench depth up to 2.3 meters. Trench length - 10 meters;
- to make a KGN well with dimensions 1500x2000 with an insulated cover and replace the existing KGN well (1000x800).
- in the KGN well, insert a DU100 tee on the inlet pipe from the pumping station DNS-22 and install two DU100 valves. Install the DU100 pipe from one valve through the wall of the KGN well to the point of connection to the polypropylene pipe of the K2 pipeline along a prepared trench with an inclination angle of at least 5%;
- to carry out installation of the DN 100 pipe from the second valve to the outlet in the rainstorm, a diversion ditch, a tie-in into an existing perforated pipe under a gravel layer. If necessary, add a layer of gravel to backfill the pipe at the exit from the well. Work to be performed in accordance with the terms of reference
