At the final stage — construction of wastewater treatment facilities for Mykolaiv

This project is critically important for providing nearly 500,000 residents of the Mykolaiv region with high-quality drinking water. It represents a significant contribution to the city’s sustainable development and a tangible improvement in people’s living conditions.

The new filtration station will comply with all modern safety and quality standards. Its multi-stage purification system will effectively remove harmful substances and seasonal pollutants from the Southern Bug River water. As a result, the water supplied through the new main pipeline will fully meet the established drinking water quality standards.

The water treatment technology at the new station will include the following stages:

  • Pre-dosing of activated carbon in slurry form directly into the pipelines. This stage promotes the adsorption of organic substances and improves the organoleptic properties of water (odor, taste, color).

  • Dosing of chemical reagents necessary for efficient water treatment: sulfuric acid for pH correction, and sodium permanganate (or sodium hypochlorite) for primary disinfection and oxidation of contaminants.

  • Feeding pre-treated water with the addition of coagulant and flocculant — to aggregate fine particles in reaction chambers where reagents interact.

  • Filtration of water through DynaDisc microfilters, which ensure a high level of purification through mechanical filtration. Disc filtration is an optimal solution when construction timelines are tight and available space is limited. This technology is already successfully used in several EU countries, including Sweden and Germany, demonstrating high efficiency and reliability in compact water treatment systems.

  • Transfer of filtered water to a pre-treated water reservoir with the addition of sodium hypochlorite for final disinfection, where it is temporarily stored before entering the final treatment stage.

  • Pumping of pre-treated water to Mykolaiv’s existing treatment facilities, where it undergoes final processing before being supplied to the city’s distribution network.

Construction is ongoing around the clock. More than 500 Autostrada specialists and over 100 units of machinery are working on the site. The installation of technological equipment, construction of monolithic structures, assembly of the station’s precast reinforced concrete floor, and architectural finishing works are in progress.

Construction and equipment installation at the treatment facilities will be completed by the end of this year. In the first quarter of 2026, commissioning and system adjustment works, as well as landscaping of the surrounding area, will take place. The system setup will be supervised by international experts to ensure that all technologies meet the highest global standards.
