The overall objectives of the project were to assist the Government of Bulgaria in ensuring compliance with the EC Urban Wastewater Directive and to protect the Danube River and its tributaries (and ultimately the Black See) from pollution by construction of wastewater treatment plants in the towns Bourgas-Meden Rudnik, Targovishte and Popovo.
The project comprised the following main activities:
- Bourgas-Meden Rudnik, demolishment of an old WWTP and construction of a new WWTP as an extended aeration activated sludge plant with biological nitrogen and phosphorus removal and sludge dewatering, lime stabilisation and emergency UV disinfection (48,900 PE) as well as 645 m collector
- Targovishte, green field WWTP as an activated sludge plant with sludge dewatering, lime stabilisation and emergency chlorination of effluent (62,500 PE) as well as 1,630 m collector
- Popovo, green field WWTP with biological nitrogen removal and aerobic sludge stabilization (37,200 PE) as well as 9,284 m sewers and collectors.
The three WWTPs are part of the Bulgarian National Programme for the Priority Construction of WWTPs for settlements with over 10,000 population equivalent. Within this programme a total of 104 plants should be completed by the end of 2010. The project is also part of the Bulgarian ISPA Strategy paper.
