This project was part of the construction of the Smokovac–Mateševo section of Montenegro’s first highway – the Bar–Boljare route, a strategic corridor connecting the Adriatic coast with the Serbian border. The stretch spans approximately 41 km of the planned 169.2 km route and runs through challenging mountainous terrain. As part of this ambitious infrastructure initiative, the development also included 45 bridges, flyovers, and 32 tunnels, designed to meet demanding technical and environmental standards.

The highway aims to enhance national and regional connectivity, stimulate economic development, and improve transport efficiency across Montenegro and the Western Balkans. To support the construction of the corridor and adjacent infrastructure, Ecol‑Unicon supplied key environmental protection solutions. In cooperation with our strategic partner BINIS, we delivered a comprehensive stormwater treatment system tailored to meet high-throughput demands and comply with European environmental standards.

Scope of work

Our partner from Bosnia and Herzegovina – manufacturer of concrete products BINIS, supplied for the aforementioned project approximately 30 coalescence separators with a nominal flow of 40 to 150 l/s using technological equipment from Ecol-Unicon, among various road construction products of their own production. We are very proud to cooperate with such a partner and to have an opportunity to use our products in such huge projects.

 

Scope of delivery: 30 coalescence separators (including separators with bypass), nominal flow from 40 to 150 l/s, manufacturer of the ESK and ESK-BII technological equipment for separators – Ecol-Unicon, manufacturer of concrete chambers – Binis, Bosnia and Herzegovina.

Applied solutions

The installed treatment units are based on high-efficiency coalescence separation technologies, designed for highway runoff. They ensure the effective removal of petroleum derivatives and suspended solids, supporting compliance with European environmental regulations.

 

The use of prefabricated, modular concrete chambers enabled rapid deployment, reliable operation, and long-term durability under heavy-load traffic conditions.

 

The project deployed reliable and efficient stormwater treatment technologies, including:

 

  • ESK and ESK-BII coalescence separators – designed to remove petroleum-based pollutants and suspended solids, in accordance with PN-EN 858, Class I.
  • Modular concrete chambers manufactured by BINIS – prefabricated solutions ensuring quick installation and robust, long-term performance in infrastructure-intensive terrain.

All units were configured to integrate smoothly with the drainage infrastructure.
