Wastewater treatment plant Litschau

Tasks definition

The capacity of the existing WWTP in Litschau was no more enough to cope with the present requirements and the treatment results did not comply with currently valid standards.
Beside the fulfilment of the detailed profile of requirements other criteria were evaluated within the design and build tender procedure.

  • Investment costs and re-investment costs
  • Operation costs (Energy, chemistry, personnel)
  • Defects liability period

It was required that the new plant shall be erected on the area of the existing plant.

Solution
  • Due to the small property area a compact 3-street activated sludge plant with SBR system was designed.
  • Rehabilitation and further operation of existing tanks – on spared area the mechanical pre-treatment and new operation building were located.

The plant was constructed according to the design and it works within the designed limits.
