Why Singapore Created NEWater: Water Security Strategy

The Challenge

Singapore is a small, dense island with no aquifers and limited rainfall catchment. Historically reliant on imported water from Malaysia (treaties expiring 2061).

NEWater Solution

Launched 2003, NEWater is high-grade reclaimed water produced by:

1. Conventional treatment.
2. Microfiltration/ultrafiltration.
3. Reverse osmosis.
4. UV disinfection.

Meets WHO/US EPA drinking standards; used for industrial processes, air-conditioning cooling, and blended into reservoirs (indirect potable reuse).

Benefits

• Supply resilience: Now ~30% of total demand; target 55% by 2060.
• Cost-effective: Cheaper than desalination or import.
• Environmental: Reduces seawater discharge, lowers carbon footprint.
• Export model: Technology licensed globally.

NEWater is a cornerstone of Singapore's "Four National Taps" (local catchment, imported, NEWater, desalination).
