Pumping sewage

General information

In areas unequipped with collective gravitational sewage system, because of unfavourable land form, geological composition of the land (watercourses) or dispersed buildings, pressure sewage system is constructed, which consists of a watertight tank, a pump, a control system and pressure fixtures. A pressure sewage system is comprised of individual sewage pumps, located on the sites of respective properties and connected to one sewage collector that discharges sewage to a sewage treatment plant.

Application

Sewage pumping stations made by Hydro-Vacuum S.A. are used in gravitational and pressure sewage systems, and are intended for transporting sewage for long distances or pumping it to an upper level. For that reason, using a sewage pumping station enables:

  • individual properties,
  • farmsteads,
  • single-family estates,
  • leisure and holiday centres,
  • industrial plants,
  • city and commune sewage systems.

that are remote from sewage collectors, to pump household sewage, drainage and rain water, as well as industrial sewage to collectors or directly to sewage treatment plants. In sewage systems, these pumping stations can be used as intermediate, area and central.

Structure of sewage pumping stations

Sewage pumping stations made by Hydro-Vacuum S.A. are complete, fully automated machines that do not require constant control.
A complete pumping station consists of four basic components:

  • one or two submersible FZ pumps,
  • tank,
  • UZS safety and control system,
  • hydraulic system.

- Pump systems

Sewage pumping stations are made with one pump system or as multipump sets. In multipump systems, one pump is always an active backup. Depending on the diameter of the pressure switch, there are three types of pumps: FZ1, FZ2, FZ3. Depending on the kind of sewage to pump and operation parameters (Q-H), the following variants of pumps are used:

  • with an FZR grinder
  • free-flow / vortex / FZV
  • with a FZB channel impeller

Pumps fitted with a grinding system allow to transmit sewage in conduits with smaller diameters (min. DN 32). Free-flow (vortex) pumps lower the risk of pump clogging. P umps with a channel impeller are used mainly for pumping rainwater, industrial sewage that does not contain long, fibrous elements.


- Tanks

Sewage pumping stations are made with four basic types of tanks;

  • polyethylene PE
  • polymer concrete
  • concrete B 45
  • polyester reinforced with fiberglass, with poured polymer concrete bottom

Depending on the requirements of the designer, the above tanks are made in diameter range from 600 to 2500 mm and heights up to 6000 mm. In the upper part of the tank is installed a manhole that enables to descend into the pumping station or take out the pumps and hydraulic equipment.
Manhole types are selected depending on the place where the pumping station is located: inside or outside a thoroughfare.

- UZS safety and control system

Operation of the pumps is controlled with safety and control devices UZS.4, UZS.7, UZS.8. Float level signalling equipment or hydrostatic and ultrasound level control systems are used. External variants of UZS safety and control systems are intended for operation in moderate climate conditions in ambient temperature of -30°C to +40°C, at relative air humidity up to 80% at 20°C, in an environment free of water and dust, gasses and explosive, flammable or chemically active vapours. The altitude of the place of installation should not exceed 1000 m above sea level. UZS safety and control devices are made from electronic and electric automatics elements, connectors and control equipment. UZS safety and control devices can be hung on building walls or immediately on pumping station tanks or in their vicinity. In the bottom part of the casing are located sealing glands, with power, receiving and control cables inside. All devices have acoustic and optical signalling of alarm conditions in the standard variant. GSM monitoring systems included in our offer are intended for monitoring the work of sewage pumping stations operating within the range of GSM networks.

- Hydraulic system

The standard internal hydraulic system consists of:

  • coupling bases with guides or without guides, so called upper equipment
  • vertical pressure pipelines
  • "SZUSTER" system of check valves
  • cut-off valves
  • collector, so called 'trousers' /two-pump pumping station /
  • connection for flushing the installation

The pipelines, collector and connecting elements are made of acid-proof steel. Coupling bases and valves are made of cast-iron and corrosion-proofed with powder paint. Additionally, pumping stations are fitted with:

  • a ladder for descending
  • work platform / for tanks higher than 5000 mm /
  • chains for lowering and hoisting pumps
  • chains for installing level signalling devices
  • gravitational ventilation system

The above elements are made of acid-proof steel / PVC ventilation /.

Advantages

  • modern construction solutions,
  • complete pipe station equipment,
  • guarantee of many years of reliable operation,
  • ease and quickness of building a pumping station in any land and water conditions, reducing earthwork and installation effort to a minimum,
  • automated, maintenance-free operation of the equipment,
  • possibility of flushing the pipelines by connecting through a 'fireman's' coupler,
  • usage of power-saving engines available also in an ex-proofed version,
  • low costs of purchase and operation,
  • constant technical supervision and warranty as well as post-warranty technical service,
  • easy access to spare parts,
  • executing individual requirements and adjusting of the product to the client's needs,
  • low costs of purchase of optional equipment,
  • high efficiency and lifetime durability under especially hard operation conditions,
  • diameter and angle of the connector pipe adjusted to the client's requirements,
  • GSM notification.
