Programs• Main Replacement Program

• Needs inventory of approximately 526 miles• Replacement rate is 0.9% of system (~72 miles/year)

• Large Valve & Meter Vault Assessments

• Cathodic Protection Evaluations

• Leak Detection Program

• Cleaning & Televising Sewers

• TCEQ SSO Initiative Program

17

TWDB Financing• May 2017 – 5 year funding commitment from TWDB

• DWU will receive $66M annually with a loan repayment period of 30 years

• Total savings could total $82.5M

• May 14, 2018 – Loan closed

• DWSRF & CWSRF

• Begin awarding contracts for pipeline replacement in FY 18-19

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)

19

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
