Making the best use of all our resources

Purified recycled water, sometimes referred to as potable reuse, is the process of using treated wastewater for drinking water that provides additional options for expanding a region’s water resource portfolio.

Potable reuse is often described as either Indirect Potable Reuse or Direct Potable Reuse.

  • Indirect Potable Reuse (IPR) involves blending purified recycled water with other environmental systems such as a river, reservoir or groundwater basin, before the water is reused for drinking water.

  • Direct Potable Reuse (DPR) involves putting purified recycled water directly into a potable water supply distribution system downstream of a drinking water plant or into the source water supply immediately upstream of the drinking water plant.
