Wastewater management and recycling includes information focused on the treatment, disposal and/or reuse of water and other resources originating from domestic, industrial, commercial effluent, as well as the effective monitoring and management of wastewater infrastructure.

Rising populations and extreme weather (both storms and drought periods) are putting increasing pressure on water supply demands, and resulting in large wastewater generation, which typically stresses receiving waters at wastewater discharge points. Recycling wastewater helps reduce high nutrient loads into receiving waters, and provides alternate sources of water for fit-for-purposes uses, reducing the demands from potable water sources.

Recycled water is commonly used for irrigation, where the higher nutrient loads provide benefits to plant growth rates, and for low-end uses.

The treatment technology is also capable of providing recycled wastewater that is treated to drinking standard, although culturally there are still stigmas against this use.
