1. Water Supply Planning
for the City Council
February 13, 2014

2. Water Supply Planning
• Background information
• Water Master Plan
• Water Demand Projections
– Both Annual and Peak Day
• State Water Planning Process
• Prop 6 and the SWIFT

3. Where Our Water Comes From
Robertson
County
Brazos
County

4. BV Groundwater Conservation District
• Regulates and Permits all of our Water Wells
– 9 wells; 7 in Simsboro aquifer provide 98% of water supply
– District-wide, Simsboro is over permitted
– Unclear what will happen when actual pumping reaches
maximum allowable – will be many years from now.
• Recent TX Supreme Court
decisions make regulation of
groundwater very uncertain.
• Any pumping restrictions
might be seen as a
“Regulatory Taking”

5. TCEQ Controls Service Areas
• Certificate of Public Convenience & Necessity (CCN)
define non-competitive utility service areas
– CS Water CCN is fully surrounded – not likely to grow

6. Water Master Plan – Aug 2010
• Conclusions in 2010
•
•
•
Water Supply is most likely adequate to “Build-Out”
Short-term Capital work is required for TCEQ Compliance
Long-term plan for future major CIP projects for Growth and Re-hab
• Future Considerations – Must closely track:
•
•
•
•
Alternate Water Sources
–
–
–
–
•
Density of development and water usage (peak day and annual)
Availability of water permitted supply
State Legislative Initiatives and Judicial Decisions
Aquifer Storage and Recovery (ASR)
Direct Potable Re-Use (DPR)
Desalination
Brazos River Authority System Operations Permit
Master Plan Update in 2014
–
Engineering Firms SOQ packages are under review now

9. State Water Planning Process
• State broken into 16 Regional Water Planning Groups
•
•
•
•
College Station is in Brazos Region G, meets in Waco
Stretches from Sweetwater to Navasota, follows Brazos River
Each Region evaluates Water Needs, Supplies, and Deficits
Regional plan identifies Water Supply strategies for State Plan
• The 2011 Brazos G Regional Water Plan
•
•
•
Includes TAMU in College Station’s numbers, and ignores CCN boundaries
Skews results in 2011 Plan (TAMU will be separate in the 2016 Plan)
Recommends the following to meet the projected shortage:
•
•
•
•
Conservation: $650,000 by 2040
Wastewater Reuse: $4.6 million by 2040
Additional Simsboro Aquifer Development: $28 million for all Brazos County
BRA System Operation (for Surface Water): $24 million for treatment plant
• Texas Water Development Board (TWDB)
•
•
•
Assembles the 16 Regional Plans into the State Water Plan
Summarizes overall data and Water Supply strategies
2012 SWP identifies water needs of Brazos County area – not city specific

10. Proposition 6 and the SWIFT
• House Bill 4 set up Proposition 6
•
•
•
•
Voters approved overwhelmingly
Completely changed Board composition at TWDB (3 full-time now)
Transfers $2 billion RDF to create the SWIFT fund
SWIFT is collateral to sell bonds, then use bond revenue for low-interest loans
•
•
•
10% set aside for rural water conservation projects
20% set aside for water conservation and reuse projects
Sets up process to prioritize water projects
• Regional Water Planning Groups must prioritize projects
•
•
•
•
•
•
State Water Planning process was NOT set up for this
“Projects” in SWP are often not separate, unique projects
Draft Priority lists are due 1 June 2014
Final Priority lists are due 1 September 2014
Stakeholder Committee is establishing standards for prioritization of projects
Criteria include: Decade of Need; Feasibility; Viability; Sustainability; and Cost
Effectiveness

11. Summary
• Permitted Water Supply adequate for future
– Keep eye on Development, Law, and BVGCD
•
•
•
•
Will update Water Master Plan this year
Will be engaged in Regional Water Planning
Will be engaged in prioritization of projects
Will pursue SWIFT loans if advantageous
