By integrating the existing obsolete site, a new 140,000 L.E. and the complete design of the complex new wastewater treatment plant with a capacity of 15,000 / 28,000 m3/d, the construction of its main technological units and its operation during trial operation. After mechanical pre-treatment, cyclic technology block with 4 parallel lines, stormwater receiving and treatment facilities. On the sludge line, mechanical compaction, dewatering, and special flat-built digesters were established. From the generated 2700 N m3/d biogas we produce thermal energy and electricity. In addition to the technological facilities, all buildings and internal infrastructure have been renovated and expanded.

In 2015, we made the operation of the plant more energy efficient by harmonizing the operation of the end lift for the treatment of treated wastewater and the water level of the receiver.
