PUB awards S$28.8 million consultancy tender to reconstruct Choa Chu Kang Waterworks

​​Singapore, 22 June 2021 – The Sin​gapore International Water Week (SIWW) 2021 started yesterday as a fully virtual event from 21 June to 2 July. Headlining th​e event is SIWW2021 Spotlight—a one-day summit that brings water leaders together to discuss and exchange ideas on innovating for a sustainable water future, followed by a power-packed SIWW2021 Online—a two-week long virtual showcase with emphasis on innovation and solutions spanning the urban water cycle, for business leaders, experts and practitioners to connect, share and learn from one another.

In conjunction with SIWW2021, PUB announced that Choa Chu Kang Waterworks (CCKWW), one of Singapore’s oldest water treatment plants, will undergo reconstruction and be transformed into a state-of-the-art water treatment facility with the latest water treatment technologies and smart capabilities to greatly enhance its operations, maintenance, safety and security when completed in 2026.

The tender to provide Professional Engineering Services for the Reconstruction has been awarded to engineering design and consultancy company, Binnies Singapore Pte Ltd for S$28.8 million. Binnies Singapore is required to provide detailed design, construction supervision and commissioning of CCKWW reconstruction project for the next five years.

The plant will be upgraded with new water treatment technologies and equipment such as high-rate clarifiers, advanced membrane filtration system and highly automated chemical preparation/dosing system, replacing the existing equipment and buildings constructed before 1981. Parts of CCKWW were earlier upgraded in 2019 with advanced water treatment processes such as ceramic membranes and ozonation-biological activated carbon filtration system. This upgraded infrastructure will not be affected by the upcoming reconstruction.

The reconstructed CCKWW is envisioned to be a fully integrated and automated plant with advanced process control capabilities to optimise plant performance, achieving an efficient resource footprint (energy, chemical and manpower) while ensuring safe water quality. Process digital twin will be incorporated to mirror the performance of the entire plant and provide water quality predictions in real-time, serving as a decision support tool to enhance operational effectiveness while doubling up as a training simulator to continuously upskill our operators.

Smart technologies and digital solutions will be adopted in its operations and maintenance—such as integrating cameras (with video analytics), headsets (that allows for real-time remote supervision) and wearable devices (with geofencing and health monitoring functions) via a structural digital twin to improve operational reliability, safety and sec  urity of the plant. New rooftop solar panels will also be added to the existing 1 megawatt-peak system, to power its operational needs and reduce its carbon footprint.
