Why NEWater ?

Strategic Intent• To promote the use of NEWater for non potable usage. This will free up large

amounts of PUB water for other potable purposes.

Singapore Water Demand

(Commercial & Industries)

(Residential)

- showering- food preparation- drinking, etc

- Steam generation in petrochemical complex- UPW in wafer fabrication plant- process use in manufacturing plants- cooling towers in commercial buildings & shopping centres

ExamplesExamples of Non-Potable Water Usage

• Processes- wafer fabrication- petrochemical - power plants, - manufacturing, etc

• Cooling towers - hospitals- commercial buildings- institutions, etc

• Others- general washing- toilet flushing, etc

Strategic Intent• To promote the use of NEWater for non potable usage. This will free up large

amounts of PUB water for other potable purposes.

2020 Plan• To expand NEWater in order to meet 40% of Singapore’s total water needs.

More affordable cost of membrane technology

PUB embarked on the NEWater initiative

Completion of Seletar NF(5 mgd)

Birth of reclaiming used water

2003/04

to conserve potable water for non-potable use

to close the water loop

2007

Completion of Ulu Pandan NF(32 mgd)

2010

Completion of Changi NF(50 mgd)NEWater first

supplied to all wafer fabs

Marketing Strategies

Switch existing customers using potable water for non-potable use by:

Target high-demand usersTarget densely populated areas

Supply to new development

23

1. Target customers with high non-potable water demand eg. wafer fabrication plants in Bedok area

2. ‘pick up’ other customersalong the way

Wafer fab customers (high demand)

Other manufacturing customers or commercial buildings (low demand)

Marketing Strategies

Bedok NF

24

Target densely populated areas (industrial/commercial) to develop a customer cluster eg. Orchard road

Marketing Strategies

25

Supply to new developments

All new commercial and industrial development proposals are required to provide a dedicated NEWater pipe system.
