Replace & Rehab Focus = Results• Goals and Benefits
• Efficient use of water supply • Recovers production capacity and costs• Reduced liability and damage to property• Improved environmental quality
• Unaccounted For Water was 6.62% for FY17 and 6.37% for FY18 with an industry goal of 10%
• Sanitary sewer overflows per 100 miles of main were 3.1 in FY18 compared to 5.4 in FY 07 (42% reduction)
• Water main repairs per 100 miles of main - 29 in FY 18 compared to 42 in FY 07 (31% reduction)

Storm Drainage Management CIP
• Erosion Control – structures threatened by creek or channel bank erosion
• Flood Management – projects recommended by master plans and hydrologic studies; bridge and culverts, channelization, detention, levee flood protection
• Storm Drainage Relief – storm drainage system improvements; pump stations
• Storm Drainage Management – provides funding for projects thru monthly storm water utility fees.

FUTURE CHALLENGES
22
Top 5 Issues Facing the Water Industry
1. Renewal & replacement (R&R) of aging infrastructure
2. Financing for capital improvements
3. Public understanding of the value of water systems and services
4. Long-term water supply availability
5. Public understanding of the value of water resources
23
Water systems are the cornerstone of
modern society, and their continuous
renewal and replacement should
be made a higher priority and not dealt
with in reaction to emergencies resulting from years of neglect and poor decisions by
the uninformed.Kenneth Mercer, Journal AWWA, July
2016

Future Challenges
• Prioritizing needs and planning to manage impacts
• Developing sustainable capital program for stormwater
• Implementing large scale improvements within funding
limitations without impacting service delivery
• Managing and using data to make replacement and
rehabilitation decisions
• Aging workforce and staffing needs
