Presentation by Ryan Kelso, Director of Water Services and Compliance for New Braunfels Utilities, for the 2019 Gulf Coast Water Conservation in Houston, Texas.

1. One Water Strategies
Managing Demand to Increase Sustainability and Resiliency

2. New Braunfels Utilities
• Municipal Utility
• Water, Wastewater, Electric
• Fast growth corridor
• Growth’s Impact: Infrastructure, Facilities,
Employees, Expectations

3. Water Resource Plan

4. One Water Approach

5. Hallmarks of One Water
A mindset that all water has value
Focus on achieving multiple benefits
Systems Approach
Watershed-scale thinking and action
Right-sized solutions
Partnerships for progress
Inclusion and engagement for all

6. One Water Strategies for NBU
• Reviewing systems and operations for
opportunities.
• Sustainability and resilience are key
management principles.
• Partner with leaders in the field for best
practices and implementation

7. Project partners
Deep dive into the Water Resource plan was conducted by a
project team at Boston University’s Institute for Sustainable
Energy, as part of a broad initiative on One Water opportunities in
Texas funded by the Cynthia and George Mitchell Foundation

9. Future demand projection
• Recent water demand growth
has been approximately 4%
per annum even as the
population increases at 6%
per annum.
• Modifying the demand
projections accordingly
indicate that NBU has
adequate supplies for over a
decade. 0

10. Demand management opportunities
• Often One Water discussions focus on the supply side, yet demand
management and water conservation also play a role
• Consideration of residential versus non-residential demand
• Informs modified demand projections
• Consideration of distribution of demand across accounts
• Ordinance modifications
• Outreach to high-consumption users
• Reviewing Rebates

11. Residential versus non-residential
consumption
• Although non-residential
accounts are very small in
number, they are significant in
overall consumption
• Therefore the assumption that
water demand would increase in
proportion with the population
increase is not necessarily valid

12. Distribution of consumption by account
• The top 0.1% of
accounts constitute
10% of total water
demand and the
top 1% of accounts
constitute 27% of
total water demand 0

13. Outreach to high consumers
• Identify high-percentile accounts
• Determine the end-uses of water
• Identify one-time change options
• Create and implement an action plan

14. Ordinances
• Review and assess how fines are assessed by volume.
• Determine cap for scaled fines by customer type.
• Create fine structures created by customer groups.

15. Current Internal Adjustments
• State of the Art Leak Detection program
• Wastewater management systems review
• Meter Replacement Program

16. Future Internal Adjustments
• Neutral Output Discharge Elimination System
• E-Pulse
• WaterSmart Customer Service Portal

17. Headwaters at the Comal

20. Phase I focus on:
• Restoration:
• Remove asphalt
• Debris removal
• Invasive species removal
• biodiversity planting and seeding
• Creation of habitat pools and ripples
• Storm Water Mitigation:
• Check dams
• Creating Berms & Bioswales
• Bank Stabilization

21. Phase II Buildings
• Comal Springs Environmental Education Center
• Event & Meeting Space
• Demonstration gardens
• Smart building applications

22. Phase II additional features
• Rainwater harvesting
• Black water reuse system
• Permeable walkways and parking areas
