SINGAPORE - National water agency PUB is looking for industry partners to design and construct a new water reclamation plant in Tuas, as well new sewer tunnels to serve the western part of Singapore, in the second phase of the Deep Tunnel Sewerage System (DTSS) project.

The new plant will treat 800,000 cubic metres of used water a day, part of which will be recycled into Newater. PUB said the long-term goal was to increase the overall water recycling rate from 30 per cent to 55 per cent of Singapore's total water demand.

By the expected completion date of 2025, about 100km of new gravity-powered sewer tunnels will convey water to the Tuas plant.

The existing DTSS sewers in eastern and northern Singapore, which channel waste water to plants at Kranji and Changi, run at depths of up to 50 metres below ground

The Tuas plant will employ technology to improve energy efficiency, reduce waste and minimise manpower through automation.

The entire DTSS project will eventually bring about a 50 per cent reduction in land taken up by used-water infrastructure, as existing WRPs such as those in Ulu Pandan and Jurong are phased out.

PUB said that it will put out calls on Apr 8 and 29 to pre-qualify consultancy firms and construction companies with established track records to participate in the project, which will ensure Singapore's water sustainability for generations to come.
