PUB awards contract to install world's largest ceramic membrane bioreactor facility at Tuas Water Reclamation Plant333https://www.pub.gov.sg/news/pressreleases/2021PR022PUB awards contract to install world's largest ceramic membrane bioreactor facility at Tuas Water Reclamation Plant25/10/2021 4:00:00 PMFacility will treat industrial used water at a treatment capacity of 75000m3 per day – the equivalent of 30 Olympic-sized poolsIssue DateOverviewAbout PUB, Singapore’s National Water AgencyFind out more about us<p style="text-align:justify;">​<strong>​​​​​​​​​​​​Singapore, 26 October 2021</strong><span> – </span> <span>PUB, Singapore's National Water Agency, has appointed Koh Brothers Building & Civil Engineering Contractor (Pte.) Ltd. to install the mechanical, electrical, instrumentation, controls and automation (MEICA) equipment for the first of Tuas Water Reclamation Plant's (WRP) two Industrial Liquids Modules (ILMs), which will treat industrial used water.</span><span> </span><span> </span></p><p style="text-align:justify;">2          The contract, valued at S$200.7 million, includes the installation of process equipment and a ceramic membrane bioreactor (MBR) system. When completed, Singapore's Tuas WRP​<sup>[​1]</sup> will house the world's largest ceramic MBR facility, with a treatment capacity of 75,000m<sup>3</sup> daily. </p><p style="text-align:justify;">3​     ​To assess the feasibility of deploying ceramic MBR technology, PUB operated a demonstration plant with a daily treatment capacity of 4,550m<sup>3</sup> at Jurong WRP since 2014. The system proved to be resilient against chemical damage and was able to treat high-strength industrial used water effectively to produce high quality treated effluent. In addition, ceramic membranes are projected to have a longer lifespan (10-15 years) as compared to polymeric membranes (5-7 years).  </p><p style="text-align:justify;">4        Koh Brothers' bid for the ILM1 contract was one of nine offers that PUB received from an open tender exercise in March 2021. Works are scheduled to commence in November 2021 and ILM1 will be commissioned by 2025. </p><p style="text-align:justify;">5          Said Mr Yong Wei Hin, Director, Deep Tunnel Sewerage System Phase 2 (DTSS2), PUB: “The deployment of ceramic MBR technology is significant in finally closing our water loop as we are now able to reclaim the industrial used water stream for reuse.  This will ensure a more resilient and sustainable water supply for Singapore. When completed in 2025, Tuas WRP will have the largest ceramic MBR system to treat industrial used water." </p><p style="text-align:justify;">6        This is the ninth major Tuas WRP construction contract awarded by PUB. Previous contracts include site development works, construction of the plant's influent pumping stations, biosolids treatment facility, civil structures for both the Domestic and Industrial Liquids Modules, product water pumping facilities as well as its monitoring and control system. </p><p style="text-align:justify;">7          Tuas WRP is a key component of PUB's DTSS2 project and will be equipped to receive both industrial and domestic used water streams from two separate deep tunnels for treatment. The plant, with an initial treatment capacity of 800,000m<sup>3</sup> per day, will be co-located with the National Environment Agency's (NEA) Integrated Waste Management Facility (IWMF) to collectively form Tuas Nexus, which integrates solid waste and used water treatment processes to harness various synergies that will improve overall plant performance and optimise land use. </p><p style="text-align:justify;">8      The DTSS2 is a S$6.5 billion infrastructure project that will enhance Singapore's water sustainability by boosting PUB's capability to reclaim and recycle water in an endless cycle. Upon completion in 2025, it will convey used water via deep tunnels from the western part of Singapore to Tuas WRP for treatment. DTSS Phase 1, which covers eastern Singapore and channels used water to Changi WRP, was completed in 2008. </p><p style="text-align:center;"> <strong>***</strong></p><p>​<sup>[1]</sup> There will be two ILMs at Tuas WRP with a combined daily treatment capacity of 150,000m<sup>3</sup>. The contract for installing ILM2 has yet to be tendered.​<br></p>​<br><p style="text-align:justify;">PUB is a statutory board under the Ministry of Sustainability and the Environment (MSE). It is the national water agency, which manages Singapore's water supply, water catchment, and used water in an integrated way. From April 2020, PUB also took on the responsibility of protecting Singapore's coastline from sea-level rise as the national coastal protection agency. </p><p style="text-align:justify;">PUB has ensured a diversified and sustainable supply of water for Singapore with the Four National Taps (local catchment water, imported water, NEWater, desalinated water). PUB leads and coordinates whole-of-government efforts to protect Singapore from the threat of rising seas and the holistic management of inland and coastal flood risks. </p><p style="text-align:justify;">PUB calls on everyone to play a part in conserving water, in keeping our waterways clean, and in caring for Singapore's precious water resources. If we all do our little bit, there will be enough water for all our needs – for commerce and industry, for living, for life. <br></p> <br><p>​<span style="text-align:justify;">Like us at </span><a href="http://www.facebook.com/PUBsg" style="text-align:justify;background-color:white;">www.facebook.com/PUBsg</a></p><p> <span style="text-align:justify;">Follow us on </span><a href="http://www.instagram.com/PUBsingapore" style="text-align:justify;background-color:white;">www.instagram.com/PUBsingapore</a><span style="text-align:justify;"> and </span><a href="http://www.twitter.com/PUBsingapore" style="text-align:justify;background-color:white;">www.twitter.com/PUBsingapore</a><span style="text-align:justify;">  </span><span style="text-align:justify;">Subscribe to our channel at </span><a href="http://www.youtube.com/sgPUB" style="text-align:justify;background-color:white;">www.youtube.com/sgPUB</a><span style="text-align:justify;"> </span></p><p> <span style="text-align:justify;"></span> <span style="text-align:justify;">Download our mobile apps: MyWaters for iOS or Android</span></p><p style="text-align:justify;">Visit our website at <a href="http://www.pub.gov.sg/">www.pub.gov.sg</a>​<br></p>​
