Potable Reuse

The quality and quantity of conventional water supplies are increasingly affected by population growth, urbanization, prolonged and severe droughts, and climate change. With an increased pressure on water systems, a diversified portfolio of water sources is required to meet future water demands, ensure public health, and provide economic and environmental sustainability. One viable approach to address existing and anticipated water shortages is to implement water reuse.

Water Conservation

Water conservation focuses on taking action to improve the effectiveness of water use through various means, such as choosing to change behavior by using those fixtures and appliances less. Water efficiency often refers to the state of water use in a community, and higher levels of efficiency implies the community uses less according to metrics such as gallons per person per day or gallons per acre of irrigated area.

Desalination

Desalination offers a means of providing freshwater from abundant saline water sources. Its use has historically been most prevalent in coastal areas, treating either seawater directly or seawater influenced groundwaters. However, as desalination technologies have advanced, the availability of conventional freshwater sources has been limited, inland water users have increasingly turned to desalination.

Operators

Access essential resources, training, and support for water operators. Enhance your skills and advance your career with AWWA.

Risk & Resilience

As stewards of public health and the environment, water professionals have always been aware of the risks associated with securing reservoirs and wells to protect the water supply, guarding materials at their facilities from theft and sabotage, and planning for routine and extraordinary events. The water sector has embraced an all-hazards approach to security and emergency preparedness that mirrors the multi-barrier approach for water treatment.

Governance

Effective governance and economies of scale are foundational to sector growth and innovation, for a future where water is accessible to all.

Wastewater

Water utilities are increasingly viewing wastewater as valuable source of drinking water and how the water and wastewater industries are very similar in the overall size of both industries, and how they both use the same technological approaches and systems. Both industries are faced with critical need for infrastructure replacement and capital expenditure.
