The Journey

1972

1998

2001

2002

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

Completion of:•Bedok NF(7 mgd) 18 mgd •Kranji NF(9 mgd) 17 mgd

Our Third Tap ���� NEWater

The Journey

11

• High-grade reclaimed water produced from treated effluent

What & Why’s of NEWater

Treated Effluent

Microfiltration• Filter out & retained unwanted particles etc.

Reverse Osmosis• RO water free from virus & bacteria.

Ultraviolet Disinfection• UV to disinfect product water.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

(Residential)

Domestic(Commercial & Industries)

Non-domestic

Non-potable water (primarily NEWater)

13

Domestic (Residential)

Non-domestic (Commercial & Industries)

Non-potable water (primarily NEWater)

Where is NEWater used?

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

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

• Others- general washing- toilet flushing, etc

14

Marketing Strategies

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

Target high-demand usersTarget densely populated areas

� Supply to new development

15

1. Target customers with high non-potable water dema nd 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

16

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

Marketing Strategies

17

Supply to new developments

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

� Total NEWater network ~ 360 km

� NEWater Infrastructure Plan (NIP)

� 87km of transmission pipelines (2200 mm dia) from Changi NF in the east to Jurong in the west via Bedok, Kranji and Seletar clusters

� Transport additional 50 mgd from Changi NF to Jurong/Tuas

� NEWater Infrastructure Plan Extension (NIPE)

� Extension 24km of transmission pipelines (2200/1600 mm dia) from NIP in Jurong to Jurong Island

� Acts as a ‘second-feed’ source forJurong Island

� Important part of Singapore’s integrated water mana gement

� linking all the NEWater factories

� managing NEWater demand as a whole

� increasing the reliability of supply
