Kamchia PSPV
The water from the Kamchia Reservoir is treated at the Kamchia Wastewater Treatment Plant. The plant began operations in 1978. In 2020, “Water Supply and Sewerage” EAD, Burgas, is implementing a project titled “Integrated Water Project for the Burgas Region.” The project is being implemented with financial support from the “Environment 2014–2020” Operational Program. The total project budget is 459.3 million BGN, of which 323.7 million BGN is grant funding. The project includes the construction of a facility for treating process wastewater generated by effluent from sedimentation tanks and filter bed backwashing.
The main activity of the Kamchia Water Treatment Plant is the purification and disinfection, through chlorination, of water from the Kamchia Reservoir for drinking purposes. The process flow is a two-stage system. Coagulants and flocculants are used to clarify the water.
The Kamchia Water Treatment Plant is designed for a total water flow of Q = 5.5 m³/s, with 400 l/s allocated for process needs.
The main facilities located on the grounds of the Kamchia Water Treatment Plant are:
• cylindrical gate;
• fish screen;
• distribution chamber;
• Parchalov chute – 2 units;
• mixers – 2 units;
• reagent storage facility, tanks for wet storage of coagulant, for preparing working solutions of coagulant and flocculant, dosing pumps;
• sedimentation tanks – 30 units;
• two-layer sand-anthracite filters – 25 units;
• filter building with a control room, laboratory, boiler room, and administrative offices;
• chlorination building. Water disinfection is carried out using chlorine gas in two stages: before sedimentation and before filtration. The water flow rates at the station’s inlet and outlet, as well as the key parameters of the treated water, are monitored daily.
Process wastewater is directed to a sand lagoon in the watershed of the Luda Kamchia River.
The treated water at the WWTP outlet meets the requirements of Ordinance No. 9 of March 16, 2001, on the quality of water intended for drinking and domestic use.
