Singapore’s Advanced Wastewater Treatment Technologies Wins Global Recognition.
This International Award recognises the most important achievements in the global water industry and acknowledges innovative technological advancements. As Singapore reclaims, recycles and re-treats used water, PUB constantly seeks ways to maximise water efficiency and lower energy use in the whole process.
The Ulu Pandan wastewater treatment demonstration plant, which started operating in 2017, was jointly developed by PUB and the Black & Veatch + AECOM Joint Venture. The demonstration plant enables PUB to test and validate advanced wastewater treatment technologies, allowing it to mitigate any operating risks before incorporating the technologies at a larger scale, at the future Tuas WRP.
The Tuas WRP is constructed as part of the Phase 2 Deep Tunnel Sewage System (DTSS) that will meet Singapore’s used water collection, treatment and disposal needs. When completed in 2025, Tuas WRP will be the largest membrane bioreactor (MBR) facility in the world, with a 30% more compact footprint compared to conventional plants.
The Ulu Pandan wastewater demonstration plant features a novel combination of treatment processes which include space-efficient inclined lamella primary settling tanks and a membrane bioreactor (MBR) system. These features shorten the process of wastewater treatment while also reducing energy usage and maximising biogas production (which can generate energy) as well as help reduce plant footprint.
At the same time, the Ulu Pandan wastewater treatment demonstration plant also incorporates automation control to reduce manpower requirements. This 12,500m3/day (2.75 million imperial gallons per day) facility is currently housed at PUB’s Ulu Pandan Water Reclamation Plant. These tested technologies will enable the future Tuas WRP to be more energy efficient – doubling the energy recovery while consuming lesser energy compared to conventional plants.
“R&D is the key driver to Singapore achieving a robust management system across the entire water loop and PUB continues to innovate to increase the efficiency of water and wastewater treatment. The Ulu Pandan wastewater treatment demonstration plant has allowed us to validate and set new standards for wastewater treatment while fulfilling our need to bring down energy use, keep things compact in land-scarce Singapore and reduce reliance on manpower. The success of this demonstration plant will ensure that the future Tuas WRP and its integrated NEWater factory can contribute sustainably towards the goal of increasing Singapore’s overall water recycling rate,” said Harry Seah, Assistant Chief Executive (Future Systems and technology), PUB.
The Black & Veatch + AECOM Joint Venture serves as the program manager for Singapore’s Deep Tunnel Sewerage System Phase 2 project and the consultant for the Ulu Pandan wastewater demonstration plant.
“Singapore continues to be at the leading edge of innovation in the water industry. This award recognises the results of harnessing advances in digital water technology together with the latest advanced water treatment processes to realize operational, economic and environmental sustainability goals at the Ulu Pandan wastewater demonstration plant,” said Cindy Wallis-Lage, President of Black & Veatch’s Water Business.
“The BV-AECOM joint venture is proud to partner with PUB to continually set global standards in integrated water management that ensures sustainable high quality water for Singaporeans. This award is a milestone in our partnership with PUB, and we look forward to contribute further to new advances in Singapore’s water management efforts,” said Billy Wong, Regional Executive for Southeast Asia at AECOM.
PUB is a statutory board under the Ministry of the Environment and Water Resources. It is the national water agency, and manages Singapore’s water supply, water catchment and used water in an integrated way. 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 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.
