Singapore has set a major milestone in its desalination journey with the opening of Tuas Desalination Plant (TDP). TDP is Singapore’s third desalination plant while it the first desalination plant to be owned and operated by Singapore’s National Water Agency, PUB. Mr Masagos Zulkifli, Minister for the Environment and Water Resources, has recently officially inaugurated the plant.
TDP is a compact plant spread across 3.5 hectares of area and has a capacity to produce 30 million gallons a day (mgd or 136,000 m3) of drinking water which will help to meet the demand of 200,000 homes. In addition to being the first plant to be owned and operated by PUB, it is also the first desalination plant to adopt a robust pre-treatment process that combines Dissolved Air Floatation and Ultrafiltration. These technologies help to reduce membrane fouling when treating seawater of varying water quality and thus enhance the operation efficiency.
Another major benefit of this desalination plant is utilization of green energy. A 1.2MWp solar photovoltaics (PV) system will be installed on more than half of TDP’s roof surface by the end of 2018. Covering over 7000 square metres of the roof surface, the solar PV system will be able to generate some 1.4 million kWh of clean energy a year and help to reduce the carbon footprint. For its use of solar photovoltaics and energy-efficient LED lightings, TDP has been conferred the Green Mark Award (Gold) in 2018.
By 2060, Singapore’s water demand will be doubled from existing demand of 430 million gallons per day
According to recent press release from PUB, TDP will help the country to boost desalination capacity from existing 100mgd to 130mgd and it is also help to meet up to 30% of the country’s water demand. By 2060, it is expected that Singapore’s water demand will be doubled from existing demand of 430 million gallons per day. The future water security of the country lies with desalination and reuse of water as such rainfall independent sources of water will help to reduce the vulnerability to weather uncertainties.
Besides Tuas Desalination Plant, Singapore has two other desalination plants – SingSpring (30 mgd) and Tuaspring (70 mgd) in operation. There are two other desalination plants – at Marina East (30 mgd) and on Jurong Island (30 mgd), which are under development. When completed in 2020, they will further strengthen the resilience of Singapore’s water supply.
