OMWD Overview
OMWD Overview
• Olivenhain Municipal Water District (OMWD)
• Located in Northern San Diego County
• Water, Wastewater, and Recycled Water Service
to approximately 68,000 residents
• Water System includes:
– 17 water storage reservoirs with a capacity of nearly 80
million gallons of water
– 26,600 meters are served
– 425 miles of potable water pipeline
– 34 MGD Water Treatment Plant
Challenges faced typically
Challenges faced typically
• Agencies face many challenges
– Aging Infrastructure
– Regulatory compliance
– Desire to maximize staff productivity
• Paper based systems are not quite up to the task
– Difficult to aggregate information
– Difficult to produce reports rapidly
– Access to information is limited
• Limited or no Integration and communication between
Systems, datasets and departments/functions
– Systems and tools that use the data to meet the different
business needs need to be acquired and integrated
– Anywhere and anytime access is crucial for operations

Hydraulic Modeling (HM) Tool
Hydraulic Modeling (HM) Tool
• Desire to perform simple fire flow and
“what if” analysis
• Existing issues with valve shut down
algorithm
• OMWD does not want to maintain a license
or staff for modeling purposes.
• All of the model input data resides within
the GIS.
Water Modeling
Water Modeling
• Conventional modeling has two
databases
– GIS database
– Modeling database
• Conventional approach of
“import/export” functionality with
some level of facility manipulation
within modeling environment
• This creates disconnects between
model and GIS
• Difficult work flow for future
updates
Water Modeling
Water Modeling
Water Modeling
Water Modeling
• IEC/Nobel Approach
– Data Model that supports EPANet
Engine
– Modeling can be performed in
GeoViewer Online (GVO)
• All model input data is included
in GIS
• True “one to one” relationship
• EPANet is the algorithm for most
commercially available software

– Bentley (Haestad)

Water Modeling
Water Modeling
• Advantages
– Small scale hydraulic modeling
can be performed in GVO with
minimal learning curve
– Hydraulic model is fully
compatible with EPANet (public
domain software)
– Updates are truly seamless if
data standards are followed
– Integration of modeling results
into GIS is easily accommodated
– Added level of QA/QC
Water Modeling
Water Modeling
• Disadvantages
– True 1-to-1 relationship
results in more costly
commercial software license
– GIS data standards must be
developed and adhered to

Future Functionality
Future Functionality
• Integration with SCADA for “real-time”
calibration and results
• Extended Period Simulations
• Water Quality Simulations
• Sewer Modeling (EPA-SWMM)
Conclusions
Conclusions
• If GIS data is available, models can be
constructed and analyzed cost effectively.
• Small learning curve
• Universal EPANet Engine is public domain
software.
• Models can still be built using commercially
available software (i.e. InfoWater,
WaterGEMS, etc…)
