Turning used water into drinking water. A growing essential for water security.

Potable reuse, the process of turning used water into drinking water, is becoming increasingly essential for ensuring water security in many regions worldwide. With access to clean drinking water being scarce in some areas, reclaimed water offers a viable solution for augmenting potable water supplies. This practice involves treating municipal used water to meet drinking water standards, providing an additional avenue for enhancing water resources.

There are two main approaches to potable water reuse:

• Indirect potable reuse (IPR) and
• Direct potable reuse (DPR).

IPR involves using an environmental buffer, such as a lake or aquifer, before treating the water at a drinking water treatment facility, while DPR treats and distributes water directly without relying on such buffers. Both approaches employ advanced multi-barrier systems, including technologies like ozonation and membrane filtration, to ensure the safety and quality of the reclaimed water.
