Ecological constructions

Ecological constructions

We strictly adhere to the designed parameters, technical norms and technological processes of the construction, which helps us, obtain high reliability in our sewage water treatment plants and the required outgoing water quality. So we always reach the best possible results, we apply our long-standing experience during the project designing. All ecological works we produce, structures and technological segments are quality assured.

For more than 60 years

  • Construction of new sewage water treatment plants
  • Reconstruction and intensification of existing sewage water treatment plants
  • Construction and reconstruction of water treatment plants and storage reservoirs
  • Construction of retention ponds



Investor: Západoslovenská vodárenská spoločnosť, a.s.

Place: Zlaté Moravce

Schedule: 06/2015

Technical parameters: 21 000 PE


The project involved expanding and modernising the existing wastewater treatment plant to address the treatment of sewage coming from Zlaté Moravce and surrounding communities, while also constructing an environmentally-friendly sewage system to serve urban neighbourhoods within Zlaté Moravce as well as the rural area in the direction of Žitavany. Work took place at the WWTP while it was in full operation. A gravity sewer line was constructed with five pumping stations to compensate for the unfavourable terrain and to pump waste water to the nearest gravity sanitary sewer, from where the sewage flows down the existing pipe to Zlaté Moravce WWTP for subsequent conversion to effluent.


Investor: Východoslovenská vodárenská spoločnosť, a.s.

Place: Stropkov, Slovakia

Schedule: 5/2014 - 1/2016

Technical parameters: 12 910 PE


Expanding the sanitary sewer system and intensifying the Stropkov wastewater treatment plant contributed toward an engineered sewer system for the Bokša neighbourhood of the city as well as toward construction of a system for the villages of Krušinec and Tisinec. The system’s extension mainly involved replacing waste collectors, relieving pressure on the sewers, raising the capacity of public sewer overflow chambers and an overall increase in the capacity of the WWTP for reliable operation, even when there is excessive wastewater. Stropkov WWTP treats municipal water biologically while removing phosphorus and nitrogen.


Investor: Bratislavská vodárenská spoločnosť, a. s.

Place: Bratislava, Slovakia

Schedule: 10/2013 - 4/2015

Technical parameters: 250 000 PE


Intensifying and modernising the Petržalka wastewater treatment plant should contribute toward a sanitary sewer system that is being engineered along the part of the Bratislava region lying along the Danube River. Because it involves a comprehensive upgrading of the water treatment plant and all of its technology during routine operation, the WWTP had to be divided into four or more streams and work was carried out while the plant was in operation. Reconstruction involved pre-treatment of raw sewage, mechanical and biological treatment, air blowing system, dosed introduction of chemicals and sludge management. A modern municipal wastewater treatment plant was constructed, using biological treatment and removal of phosphorus and nitrogen, with minimal operating costs.


Investor: Trnavská vodárenská spoločnosť, a.s.

Place: Leopoldov, Slovakia

Schedule: 2012

Technical parameters: 5 500 PE


The proposed building is located within the existing Leopoldov WWTP, where the actual wastewater treatment plant had not been in operation. Emphasis was placed on expanding the WWTP and in reconstructing and upgrading it. A new municipal wastewater treatment plant was constructed to treat sewage mechanically and biologically while removing phosphorus and nitrogen. Wastewater is mechanically pre-treated, where pressure from excess rainwater can be relieved (1:4 ratio). Leopoldov WWTP works biologically by actively stabilising sludge aerobically, where the activation level corresponds to upstream denitrification.
