Research Session
Water research plays a pivotal role in advancing our understanding of water challenges and developing innovative solutions. Researchers explore cutting-edge treatment processes and technologies contributing to our understanding of the water ecosystem and developing treatment processes addressing the most difficult water contaminants. University Forums showcase the latest in academic research.
Capital Improvement Projects: Design, Construction, and Delivery
Water systems are a vital, yet costly, component of every community, and every penny spent is scrutinized by policymakers and ratepayers. Capital improvement projects encompass the comprehensive process of designing, constructing, and delivering essential water infrastructure enhancements. This session explores the journey of a capital improvement project from innovative and sustainable designs, new building techniques, and materials to the latest in project delivery strategies.
Utility Risk & Resilience
The frequency of billion-dollar extreme weather events — from hurricanes, flooding, and rising sea levels to droughts, heat waves, and wildfires — has increased dramatically in recent years. Resiliency efforts of water and wastewater utilities not only save lives and taxpayer dollars, but also play a key role in preparing cities for the challenges they face from these events. Join experts as they discuss provisions in the newly promulgated America’s Water Infrastructure Act of 2018 legislation for assessing risk and becoming more resilient from not only Mother Nature, but also cyber hazards.
U.N. Sustainable Development Goals
To guide global collaboration on sustainability the United Nations defined 17 Sustainable Development Goals. The SDGs represent the world’s best plan to build a better world for people and our planet by 2030. Adopted by all United Nations Member States in 2015, the SDGs are a call for action by all countries — poor, rich and middle-income — to promote prosperity while protecting the environment.
AWWA’s work directly supports these SDGs:
#6: Clean Water and Sanitation
#5: Gender Equality
#10: Reduced Inequalities
