Meden Rudnik Wastewater Treatment Plant – Meden Rudnik Urban Area

The wastewater treatment plant was built by the Municipality of Burgas on the site of the old plant between 2007 and 2009. In 2023, the plant underwent a renovation that included the construction of two new biological treatment tanks, a secondary clarifier, and a SCADA system. The system is monitored and controlled locally and can also be managed via the Internet.
The treatment plant has been transferred to “Water Supply and Sewerage” EAD, Burgas, for management, maintenance, and operation.
The “Meden Rudnik” WWTP treats wastewater from the Meden Rudnik neighborhood. The plant’s design capacity is 48,900 PE, and the permitted annual water volume is 2,490,030 m³/y.
