Wastewater reuse involves the process of treating and repurposing wastewater for beneficial applications, as opposed to releasing it directly into the environment. By employing diverse treatment techniques, wastewater undergoes purification to meet defined quality criteria, enabling its use in activities like irrigation, industrial operations, landscaping, and in certain instances, even for potable water purposes.

Wastewater reuse plays a vital role in water resource conservation by diminishing freshwater usage, lessening environmental repercussions, and fostering sustainable water management practices. This approach contributes significantly to building a resilient and sustainable future.
