ABB awarded $40.5m Tuas Water Reclamation Plant contract

The tech firm will deliver a site-wide plant monitoring and control system.

National water agency PUB has awarded Swiss tech firm ABB with a $40.5m contract to deliver a complete site-wide plant monitoring and control system for the Tuas Water Reclamation Plant (Tuas WRP).

Tuas WRP will receive used water flows from the western part of Singapore via two separate deep tunnels.

It will also apply membrane bioreactor (MBR) technology to treat and purify 650,000 cubic metres of used domestic water per day, to generate “NEWater”, whilst 150,000 cubic metres per day of used industrial water will also be treated and sent back to industries for reuse.

MBR is a filtration process where membranes are used to separate different substances.

ABB will deploy process control systems across multiple facilities at the site. The overall system will integrate over 100,000 input/output signals from different assets, including pumping stations and a wet weather facility to provide complete visibility of operations across the plant network.

Alarm monitoring and security systems will be added to ensure industrial control, including cyber security solutions that assess threats and test vulnerability.
