Ensuring Reliable and Efficient Treatment Plant Performance

The effectiveness of a water or wastewater treatment plant (WWTP/WTP) depends not only on its design but also on proper operation and regular maintenance. Our Operation & Maintenance (O&M) services ensure that treatment plants run at peak efficiency, avoid costly failures, and comply with environmental regulations.

With over 20 years of experience, we have successfully managed WWTPs in Vilnius, Švenčionys, Šalčininkai, and other locations, ensuring cost-effective operation and reduced downtime.

Professional Maintenance for Long-Term Reliability.

Water and wastewater treatment plants require continuous monitoring and maintenance to function efficiently. We help public and private clients reduce operational costs, increase system longevity, and prevent failures.
