CST to Supply Tanks for NEWater Project in Singapore
CST Industries, Inc. of Kansas City, Kan., signed a contract with Keppel Seghers Engineering Singapore Pte, Ltd. for the supply and installation of two 22,000 cubic meter finished water storage tanks for Keppel Seghers’ Ulu Pandan NEWater DBOO project in Singapore.
In Singapore, the clean water reclaimed from used water by means of advanced membrane technology is called NEWater. The Keppel Seghers plant will produce 25 mgd of NEWater. NEWater meets international standards for potable and drinking water, and will be used largely for industrial installations with a small amount going into reservoirs for indirect potable use.
The tank contract covers the design, supply, fabrication, delivery to site, installation and commissioning of the two pre-engineered and pre-fabricated sectional steel storage tanks. Each tank will have a nominal working capacity of 22,000 cubic meters and is 52 meters in diameter with a wall height of 11.5 meters. Each tank will feature an aluminium geodesic clear-span dome roof system. The tank and dome systems will be supplied by Engineered Storage Products Co. of DeKalb, Ill. Engineered Storage Products Co. is an operating division of CST Industries.
The tank wall sheets will be internally coated with Engineered Storage Products Co.’s proprietary Kuo-Lon modified epoxy coating system. This state-of-the-art coating is specifically designed to minimize long-term maintenance requirements, a crucial issue for Keppel Seghers’ 20-year DBOO contract.
