About Moulton Niguel Water District
MNWD & theOC Watersheds
Watersheds and Urban Runoff• SDRWQB regulates MS4 discharges in South OC
• Includes dry-weather runoff from over-watering
• South OC Water Quality Improvement Plan
• Estimated at >$1 billion liability
• Who is responsible for curbing urban runoff?
• Who pays for interventions/mitigation?
• Cities and counties are tasked with management
• Ultimately everyone’s responsibility
Urban Runoff Collaboration
• Reduce runoff and improve quality of local creeks and beaches
• Regional data integration
• Education & targeted marketing
• Develop interactive watershed tools
• Explore resource recovery options
Multiple Benefits of Water Efficiency• Save water and money
• Reduce runoff & avoid property damage
• Improve quality of local creeks and beaches
• Delay investment in infrastructure/storage
• Keep water rates low
Water Budget Based Rate Structure• Most effective demand management tool
• Provides customized water budget for each meter
• Indicates efficient level of monthly water use
• Indicator of leaks and over-watering
Engagement and Education Through a Variety of Channels

Regional Data Inventory & IntegrationMNWD
• High resolution meter data
• Water efficiency incentive data
• Continuous, historical data sets
OC PUBLIC WORKS
• Collector data from stormwater outfalls
• OC Stormwater Tools
• Interactive BMP Asset Tracking Portal
• Limited # of collectors, not continuous
Spatial Overlay: Outfall Tributaries & MNWD Meter Locations
‘Urban Drool Tool’
• Interactive, data visualization tool
• Search by Address feature
• Displays key data:
• Number of homes
• Census data
• Water quality & flow
• Percent within budget
• Number of Rebates
OC Stormwater Tools• Internal BMP & Asset tracking tool
• Displays key data:
• Water consumption data
• Outfall flow data
• Outfall prioritization
• Water quality monitor
• Informs targeted marketing &
decision-making
Application Abilities
Where to Deploy BMPs basedon outfall prioritization
What Type of BMP based on water use and flow data
How will the BMP impact the surrounding area over time
• Builds on AMI network, cloud-based platforms, &
watershed flow and water quality monitoring
capabilities
• Better understanding of year-round dry and wet
weather flows in Aliso Creek
• Potential for runoff and pollution reduction as well as
resource recovery in the Creek
