Bi-communal reuse of treated effluent in Cyprus
Cyprus is using almost all of its renewable water resources. Groundwater is rapidly depleting and sea water intrusion is occurring in the main coastal aquifers. Providing water for the expanding domestic and tourism sectors, while maintaining the agricultural sector, is becoming a critical issue. Complicating matters of water management, the island has been divided since 1974 into the Republic of Cyprus, the internationally recognized government, and the ‘Turkish Republic of Northern Cyprus’, which is recognized only by Turkey. However, the island's water resources do not conform to map lines and shared infrastructure predates the division, creating unique challenges for the island's two communities. With objectives to enhance bi-communal ties and address common water shortages, a feasibility study was recently performed to identify opportunities for reuse of 30,000 cubic metres per day of treated effluent generated by the New Nicosia Wastewater Treatment Plant (WWTP). The WWTP is being constructed to replace the Mia Milia/Haspolat WWTP, which services both the Turkish Cypriot community (TCC) and Greek Cypriot community (GCC) of the Nicosia area. The project involved transmitting treated effluent to TCC and GCC, benefiting both communities. The study scope included identifying opportunities for reuse, and identifying and assessing water storage and conveyance alternatives.
