EDP dry pumping stations


EDP dry pumping station is a compact device, which guarantee reliability and safe operation.

The dry sewage pumping station SZUSTER system is the solution with the growing popularity. Users emphasize the flexibility of our technology – the possibility of using pumps from any manufacturer, depending on preferences. EDP dry pumping station complying European regulation EN 12050-1. Our technology solves the current problems of odours.

The structure of an external pipe retention tank and a distributive tank provides the right amount of retention space for pumping sewage and reduces dead retention space minimizing odours.

The EDP dry pumping station consists of two main elements: an external pipe retention tank and a dry chamber (a technological part) with the fittings, pumps and control automation inside. An external pipe retention tank is designed to protect the pump from damage solids contained in the municipal wastewater. It works as a separator, where the larger solid parts are retained and dosed gradually to ensure the safety of the entire system. We recommend cleaning a pipe retention tank twice a year.

Technical data

  • Comply with harmonized norms: PN-EN 12050-1, PN-EN 12050-2, PN-EN 12050-4.
  • Comply with the requirements of the Regulation of the European Parliament and of the Council (EU) No. 305/2011.
  • Possibility to use any manufacturer pumps.


  • Pumping municipal or industrial sewage.
  • Pumping stations: main, zonal or local.
  • Technological buildings with dry pump location.

In comparison to traditional dry pumping stations the EDP dry pumping station eliminates the risk of the formation of so-called sewage sludge, which is gradually being distracted can result to pump damage. EDP dry pumping stations have many advantages.

For Users

  • Fittings and pumps protection from sudden polluted wastewater discharges of solids through the use of the horizontal pipe retention tank.
  • Safe and hygienic operation by placing the technological part in the dry chamber.
  • The possibility of cutting off the system and service the pump units in hygienic conditions.
  • Limiting the dead retention space to a minimum and thereby minimizing the occurence of odors.
  • The possibility of installation in close proximity with residential buildings or outbuildings.

For Engineers

  • Limiting the dead retention space to a minimum and thereby minimizing the occurence of odors.
  • The possibility of using any manufacturers pumps.
  • The possibility of installation in close proximity with residential buildings or outbuildings.

Product development is our priority. We listen carefully to the opinion of our customers, thus constantly creating new versions and improvements.

Operating principle of EDP dry pumping station

The EDP dry pumping station constitutes a complete and fully automated installation.

The EDP dry pumping station constitutes a complete and fully automated installation, consisting of a technological pre-set built together with pumps in the dry chamber and cooperating with the external retention tank.

Sewage flows to the pumping station through the cascade well and the pipe storage tank. Sewage flowing to the pumping station is directed to the distributive tank, to which pump units are attached. Pump units are automatically and alternatively powered up once an adequate level of waste water has been reached in the distributive tank. This level is measured by hydrostatic pressure converter, in the case of failure – by high and low level alarm sensors. The hydrostatic pressure converter and alarm sensors are installed in the distributive tank and cooperate with the electric switchboard executing a predetermined control algorithm in the automatic operation system. With an intense inflow and when the power-up level of one of the pumps has been exceeded, the other pump is powered up. The capacity of the distributive tank as well as the output and the number of pump units are selected taking into account the quantity of sewage inflow. The whole dry sewage pumping station is installed in a dry chamber (prefabricated concrete or polymer concrete rings either plastic chambers), which allows a direct inspection of the correctness of the pumping station operation. It also facilitates the disassembly, replacement and the maintenance of its individual elements in hygienic conditions.

* The minimum retention capacity is calculated according to the minimum pumps efficiency and the numbers of starts (no more than 10 cycles/hour) of a single pump. The specified capacity may be reduced when using pumps with higher possible numbers of cycles/hour and/or when inflow is less than maximum.
