C.4.4. Wastewater Treatment Plant Project Approvals

WWTP Project Approval works and procedures have been carried out by the MoEU since 2004 in
order to ensure the selection of wastewater treatment technologies that will provide the desi-
red level of treatment efficiency and have low investment and operating costs during the cons-
truction phase of wastewater treatment plants (WWTP). Wastewater treatment plant project
approvals are carried out within the scope of the “Circular on Wastewater Treatment/Deep Sea
Discharge Plant Project Approval” numbered 2018/14, and a total of 1,208 Wastewater Treatment
Plant Project Approval procedures were carried out by the MoEUCC, 69 of which were carried
out by the General Directorate of Environmental Management (GDEM) of the MoEUCC between
2019-2023.
