Municipal Wastewater Treatment Plants

We design and supervise the construction of mechanical and biological wastewater treatment plants (WWTP), primarily with anaerobic sludge treatment, fulfilling the highly strict norms of Austrian environ- mental regulation. We also upgrade existing plants and are therefore able to equip our projects with state of the art technology.
