Peab has been commissioned to rebuild and extend the Lucerna wastewater treatment plant in Västervik. The customer is Västervik Miljö och Energi AB and the contract is worth SEK 248 million. The Lucerna treatment plant in Västervik, which treats wastewater for the city of Västervik, will undergo an extensive renovation and extension.

The plant was built in 1972 and needs to be upgraded to meet stricter laws and environmental requirements and be prepared to handle greater amounts of wastewater. The capacity expansion will result in a state-of-the-art facility that will also contribute to improving the situation in the Baltic Sea through the latest purification technology. The treatment plant will be equipped with a new intake building and filter building.

Pools will have flexible zones with smart digital steering and these modern facilities will contribute to a sustainable working environment. The entire project is characterized by sustainability thinking. Existing buildings will be preserved as far as possible, and made more efficient to reduce energy consumption.

The plant will have an energy self-sufficiency rate of 70 percent with solar panels and electricity and heat generated by a gas engine. In addition, rainwater will be treated before it reaches the sea, which means a cleaner Baltic Sea. Peab's commission is a shared contract and will start in May 2024.

Completion is scheduled for March 2028. The project will be order registered in the second quarter 2024.
