AWWA’s State of the Water
Industry Survey
• Identifies and tracks significant
industry challenges
• Data and results support
development of strategies for
current/future issues
• Inform decision makers and the
public of water industry
challenges

State of Water and Sewer
Infrastructure
Water and sewer systems built and
financed by previous generations are
approaching or have exceeded their
useful lives
• Revenues do not fully cover costs
• Difficulty in financing
• Public acceptance of rate increases

Financing for Capital Improvements
![Page 16: North America Water Industry · 2014-12-04 · North America Water Industry Jim Chaffee, P.E., BCEE Immediate Past President International Forum On Water Supply Japan Water Works](https://reader033.vdocuments.us/reader033/viewer/2022053008/5f0bcdd67e708231d4324b9f/html5/thumbnails/16.jpg)
Long-term Water Supply Availability
• Short-term water shortages (natural/regulatory conditions or system failure)
• Long-term shortages: population and climate changes
• Groundwater overdraft and lack of management
• Options for constrained supplies– Conservation: has momentum, seeing impacts in
reduced demand
– Desalination: expensive, energy intensive, brine management
– Reuse: public perception

“How prepared is your utility to meet its long-
term water supply needs”

Public Understanding of the Value
of Water
• Industry mission less urgently visible
• Clean water & sanitation are taken for granted
• Lack of public support for sustainable water rates
• Industry needs to attract new talent for a sustainable workforce
![Page 21: North America Water Industry · 2014-12-04 · North America Water Industry Jim Chaffee, P.E., BCEE Immediate Past President International Forum On Water Supply Japan Water Works](https://reader033.vdocuments.us/reader033/viewer/2022053008/5f0bcdd67e708231d4324b9f/html5/thumbnails/21.jpg)
Regulatory Environment• Regulations
– U.S. EPA Regulations
– Canada Provincial Regulations
• Regulations have resulted in significant technology development in past 3 decades– Filtration, Microbial contaminants, D/DBPs, SOCs
and IOCs
• Continued pressure to address unregulated contaminants– Chromium, perchlorate, organics, pharmaceuticals
