Mostar is one of the largest cities in Bosnia and Herzegovina, home to over 100,000 citizens. However, the city’s water and sewerage systems are not adequate. For instance, the existing sewerage system is only 50 km long and it covers only certain parts of the city, while the wastewater is drained directly into the Neretva and Radobolja rivers, seriously impacting the environment and endangering water quality downstream.
The WBIF (EU) grant provides support for the construction of 14 km long sewer collectors, on both Neretva river banks, and one lateral collector, 1.150 km long. The collectors are designed to intercept the existing river outfalls and convey the wastewater to the wastewater treatment plant, which was built in parallel under a separate contract. The left bank collector conveys wastewater, while the right bank collector conveys combined storm and wastewater and includes overflow chambers with stormwater outlets. The project is currently under construction.
