Sewage pumping stations are designed for pumping stormwater and close to them in the composition of wastewater that meets the " Rules of reception of wastewater in the municipal Sewerage system."
Operation of the station can be carried out at ambient temperature from - 50 to + 40oC.


The CNS consists of a buried tank with submersible pumps installed in it. The capacity is equipped with a service platform and a ladder. The control Board of submersible pumps of external execution is insulated in a shell protecting from precipitation and moisture.
The receiving tank is a round polyethylene container designed to receive wastewater and transport it using submersible pumps.
The following equipment is installed in the receiving tank:

  • basket for the detention of large garbage;
  • submersible pumps (1 working, 1 standby) on automatic pipe coupling;
  • ventilation ducts;
  • set of technological pipelines;
  • float level indicators.

Working process.

The pumps work in automatic mode. When the scheme of the pumping station –
1 working + 1 standby all pumps are mounted in the CNS and each of them is designed for maximum hourly performance. In this case, the pumping station works in three modes:
I. The estimated load of the pumps, turning on alternately, pump out incoming water.
II. The peak load occurs in the case when the number of incoming sewage exceeds the capacity of a single pump. When filling the station to a critical point, a second pump is additionally switched on, increasing productivity.
III. Emergency - when filling the station to the emergency level, the light and sound alarms are triggered. Overflow can be caused by shutting off the pumps, increasing the volume of incoming sewage or other reasons.
The receiving tank of the CNS is equipped with hatches and a ladder for the possibility of servicing the equipment located in the tank.
