Bids have been submitted by consultants for two large water supply projects planned by the State Hydraulics Works (DSI). These are the $270 million Yesilcay water supply project for Istanbul, and the $100 million Manavgat water export scheme (MEED 3:6:94; 15:4:94).

Tender evaluation is expected to take about two months for each. International firms in the ventures bidding for the Yesilcay project include: CH2M International and Black & Veatch International of the US, France's Safege, Sweden's Sweco, Lahmeyer of Germany and the UK's Sir Alexander Gibb & Partners and Mott MacDonald. A number have nominated Turkish, and in some cases Kuwaiti, partners.

The Kuwait Fund for Arab Economic Development will extend a credit of around $80 million for the project. It calls for the construction of two regulators on separate rivers, a 60-kilometre transmission pipeline and a water treatment plant with a capacity of 500,000 cubic metres a day.

Local and foreign firms in the bidding for the contract to supervise the construction of offshore works for the Manavgat project are:

France's DVO Consulting with Yuksel Proje and Temelsu

the US' Intec Engineering

the UK's JP Kenny & Partners with HES Muhendislik

the UK's OGI

the US' H Padron Associates, the Danish Hydraulic Institute, and Su Yapi.

The contract was retendered when bids came in too high in the spring. The offshore works of the Manavgat project comprise a valve control chamber on the shore, four submarine pipelines, and two single-point mooring facilities. The onshore works, including a water intake structure, pumping stations, pipelines and water treatment facilities, have already been completed. The Manavgat project is expected to supply water to Middle East customers. Israel has already expressed an interest in the scheme.

Prequalification applications are also due to be returned by consultants to the DSI on 30 September for the $1,400 million Greater Melen River project (MEED 22:7:94).
