Investments in four wastewater treatment plants in Belarus are accelerating!



PRESTO project aims at decreasing excess load of nutrients to the water bodies by carrying out investments in enhanced nutrient removal at four wastewater treatment plants in Belarus: Baranovichi, Grodno, Molodechno and Vitebsk. 

Preparation of investments started in 2012 with the technical audits at each of the wastewater treatment plant. The technical audits were carried out by Pöyry Finland Oy, hired by John Nurminen Foundation which is in charge of investment part in PRESTO. 

The work included gathering of needed baseline data on the current technical processes, planning of the most cost effective and feasible solutions for improved nutrient removal as well as preparing tender documentation for the investments that are going to be realized. The necessary technology to decrease the concentration of phosphorus in purified wastewater in order to achieve HELCOM recommendation was selected.

Technical reports became the solid basis for further work and showcase the diverse challenges to be addressed in each of the four waste water treatment plants. The four wastewater treatment plants are now about to complete their first tender procedure in PRESTO for the local design to adjust the technical designs into Belarusian local context. 

As a next step, tenders for construction works, equipment supply and installation will be launched.

All four PRESTO investing partners are discharging their waters to Neman and Daugava rivers which belong to Baltic Sea catchment area. As a consequence, reducing trans boundary nutrient load from Belarus will improve not only water quality of European rivers but also the state of the Baltic Sea.

  1. Thank you for sharing. Nutrient removal is becoming a growing challenge for operators of anaerobic digestors at cattle and dairy farms. Removal of nutrients in wastewater is costly.
