One Water StrategiesManaging Demand to Increase Sustainability and Resiliency
New Braunfels Utilities
• Municipal Utility
• Water, Wastewater, Electric
• Fast growth corridor
• Growth’s Impact: Infrastructure, Facilities, Employees, Expectations
Water Resource Plan
One Water Approach
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
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
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

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.

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
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

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

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
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.
Current Internal Adjustments
• State of the Art Leak Detection program
• Wastewater management systems review
• Meter Replacement Program
Future Internal Adjustments
• Neutral Output Discharge Elimination System
• E-Pulse
• WaterSmart Customer Service Portal
Headwaters at the Comal
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
Phase II Buildings
• Comal Springs Environmental Education Center• Event & Meeting Space• Demonstration gardens• Smart building applications
Phase II additional features• Rainwater harvesting • Black water reuse system • Permeable walkways and parking areas• Smart building applications• Low impact development – reuse of materials
