Greater Melen River:

a weir on the Greater Melen river, drawing off 8.5 cubic metres (cm) a second, or 268 million cm a year (cm/y);

the Melen and Cumhuriyet pumping stations, respectively requiring 22.5 MW and 5.8 MW of electricity respectively a 150-kilometre transmission pipeline between the Melen and Cumhuriyet pumping stations, made up of steel pipes with a diameter of 2.5 metres, and re-inforced concrete cylinder pipes with a diameter of 3.0 metres the Alacali transit dam, a rock-fill structure impounding a reservoir with a volume of 1.05 million cm the Cumhuriyet water treatment plant with a capacity of 700,000 cm a day a 25-kilometre transmission pipeline between the Cumhuriyet plant and a water tank at Kagithane. Made up mainly of steel pipes with a diameter or 2.5 metres, this will include a tunnel under the Bosporus with a length of 3 kilometres and a diameter of 3.6 metres supply of steel pipes, valves and ancillaries in three portions 177 kilometres of 154kv electricity transmission lines.

Yesilcay scheme:

two weirs on the Sungurlu and Isakoy rivers, together with water conveyance canals construction of a pumping station and a storage tank at Kurfalli, plus the laying of a total 13.25 kilometres of steel pipes and pre-stressed concrete cylinder pipes with diameters ranging between 2.25- 3.0 metres between Kurfalli and the Darlik reservoir a new water intake at the Darlik reservoir, a tunnel, an acqueduct over the Omerli reservoir, and the laying of 22.5 kilometres of steel pipes and prestressed concrete cylinder pipes with diameters ranging between 2.2-3.0 metres between Darlik and the Emirli pumping station supply of all the required pre-stressed, concrete cylinder pipes with a diameter of 3.0 metres from the State Hydraulic Works’ Tuzla pipe factory, together with related valves, fittings, spare parts and ancillaries. The pipe factory will be rehabilitated as part of this contract supply of steel pipes and related valves, fittings, spare parts and ancillaries construction of a new treatment plant at Emirli with a daily capacity of 600,000 cm installation of two I 54-ky transmission lines a supervisory control and data acquisition (SCADA) remote control electronic system.
