Overseas Projects

Water Supply projects in 16 settlements in Tripoli Region of Libya.

 TTI was commissioned in April 2006, as part of a Consortium of Design Consultants for designing infrastructure – water supply, sewerage and storm water drainage –in some settlements in the Tripoli Region in Libya

The source of water supply was the Great Manmade River( GMMR) in Libya. New storage and distribution networks were designed adequate to provide a minimum of 15 m pressure to all consumers. The networks have up to 500mm diameter Ductile iron pipeline. Each settlement had about 40 km of distribution network, ground level reservoirs and overhead tanks. In all TTI designed 42 transmission mains totaling 110km in length, 24 pumping stations, 20 ground level reservoirs, 16 elevated water tanks, 560 km of distribution mains and 4 water treatment plants using rapid sand/ dual media filters.The estimated project cost for water supply component was US $ 72 million.           [ back ]
