Wastewater treatment plant shall be designed according to EN or other international standards. The  contractor should use related design standard values. If the Contractor intends to use a patented  process that is also complied with this Employer’s Requirements, the Contractor shall provide all  relevant information about this system to the Employer during the tender period. The proposed system  should be technically and operationally proved in the site in three similar plant with similar capacity.  Giresun wastewater treatment plant will be constructed in one stage. The capacity of treatment units  which is the subject of works of these Tender Documents, will be enough to satisfy the estimated  wastewater treatment needs of Giresun up to 2047. The design parameters for the Giresun wastewater  treatment plant are set out below.
