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

slide-23
SLIDE 23

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.

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
