Direct potable reuse

Definition

Direct potable reuse refers to the process of treating wastewater to a high standard so that it can be directly introduced into a public drinking water supply system, thus ensuring a safe and sustainable source of water. This method of water reuse is increasingly recognized as a viable solution to address water scarcity, reduce wastewater discharge, and meet the growing demand for clean drinking water. It involves advanced treatment technologies that remove contaminants to levels that meet or exceed health standards.
