Optimized water

Access to clean water is an increasingly critical global and Southwest regional issue. ASU conducts research, education and engagement in the water arena and is working to optimize water use in operations.


  • Achieve 15 percent reduction in water imported to the university by fiscal year 2023.
  • Incorporate university research into water and wastewater operations to harvest energy and nutrients from university effluent by fiscal year 2025.
  • Incorporate university research into water and wastewater operations to develop campus community health goals, metrics and baselines by fiscal year 2019.

日本一本道a不卡免费Optimizing water includes reducing the need for water, eliminating water waste, and using the most-appropriate quality of water for the right use. For instance, drinking-quality water is not needed for use in cooling towers, toilets and landscaping. Significant energy is required to produce drinking-quality water, so using less-refined water for the right use can also lead to energy savings and fewer climate change-contributing emissions.

日本一本道a不卡免费Considering the circular resource system perspective, wastewater is a resource rather than waste. Wastewater contains water, chemical energy and nutrients. ASU is actively researching methods to extract these resources from its wastewater and close that resource loop, thus displacing a portion of the water, energy and fertilizers currently imported onto campus.

ASU is also actively designing new buildings with water-efficient fixtures and equipment, retrofitting existing buildings with water-efficient fixtures, analyzing campus water infrastructure for savings opportunities, implementing low impact development practices, and implementing new landscape irrigation controls for improved efficiencies.

Progress charts

Water use declined by 10.2 percent between fiscal years 2007 and 2017 and wastewater generated declined by 14.6 percent.
