PUB, the national water agency of Singapore, has selected Black & Veatch to help with a major upgrade of Chestnut Avenue Waterworks (CAWW), the country's largest water treatment plant which was first built in 1975.
Black & Veatch will provide engineering consultancy services for the upgrade works at CAWW. The company’s role will include the study, design and supervision of the construction and commissioning of the works.
One of the key challenges is a requirement for the works to have minimal effect on the plant’s current water production.
“The exciting challenge from a technical perspective is that we will be upgrading the plant and equipment in parallel with the on-going water treatment processes,” said Desmond Lim, Project Director, Black & Veatch. “Not only are we enhancing the treatment facilities, we are also ensuring that the production of drinking water at the plant remains uninterrupted.”
The plant upgrade is part of PUB’s efforts to continually upgrade the water treatment capabilities of its facilities. This is done in anticipation of future water quality trends, especially those related to treatment of water from urban catchment, and as well as to bring new cost efficiencies to help manage rising cost pressures.
Upgrade works at CAWW Stage 1 and Stage 2 will include ozonation and biological activated carbon processes, and replacement of aged plant and equipment.
CAWW is the largest drinking water plant in Singapore, treating 120 MiGD (million imperial gallons per day). Black & Veatch was appointed as Owner’s Engineer for Stage 1 and Stage 2 in 1975 and 2001 respectively. The new upgrade will be completed by 2020.
