Chestnut Avenue Waterworks to experience minimal operational downtime during upgrading works
Singapore’s largest water treatment plant is set for a major upgrading in the coming months.
PUB, the national water agency of Singapore, has selected Black & Veatch to help upgrade Chestnut Avenue Waterworks (CAWW), first built in 1975. One of the challenges is that the works will 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.”

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.
“When you talk to water utility leaders around the world, often aging infrastructure is one of the main issues that keeps them up at night,” said Cindy Wallis-Lage, President of Black & Veatch's water business. “Investing in aging assets and addressing the issue earlier rather than later helps reduce future risks, improves efficiencies and reduces operational costs.”
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.
- Aging infrastructure is one of the top three issues facing water utilities in the US, according to Black & Veatch’s 2013 Strategic Directions report.
- Black & Veatch has been delivering innovative water solutions in Singapore since 1922
