According to the proposed option in RPIIP and the conducted examination of the wastewater treatment plant in Albena and based on the attached sizing, the following measures are proposed to achieve compliance with the applicable European and Bulgarian legislation:
Reconstruction and modernization of the wastewater treatment plant in Albena, including the construction of a system for mechanical treatment, biological and physicochemical removal of phosphorus, a bioreactor with "nitrification and denitrification" and mechanical dewatering of the sludge. Construction of a KIPI/SCADA management system, as well as a real-time control system. Main parameters of the contract scope: The capacity of the existing wastewater treatment plant in Albena is for 19,000 PE, only for BOD5. The existing discharge collector to the discharge point is gravitational - asbestos-cement pipeline Ø475, with a length of 4000 m. It passes through the beach area of the village of Kranevo in the area of the beach "International Children's Camp".
The quality requirements for the treated waters, according to the current permit for the use of a water object for the discharge of treated wastewater into surface water bodies, water object Black Sea No. 23310004/ 22.04.2013, are:
BOD5=25 mg/l;
COD=125 mg/l;
SS=35 mg/l;
N=15 mg/l (*10 mg/l) and
P=2 mg/l (*0.7[1] mg/l). [1] * Requirements according to the revised Directive (EU) 2024/3019 for the treatment of urban wastewater, effective from January 1, 2025.
Currently, the discharge permit is in the process of being updated. The procedure is outside the scope of this contract. The updated discharge permit will be presented to the Contractor subsequently, as in the process of investment design and construction, it must comply with the parameters according to the cited directive.
The detailed description of the client's requirements for the execution of the contract, as well as the intended types and volumes of work are contained in the Technical specifications (Client's Requirements) and the other documents attached to the contract.
The contractual conditions are according to FIDIC - Yellow Book.
The object is a second category construction according to the ZUT.
