Norwalk Service Area GIS |
iWater used existing CAD drawings to assess valve and fire hydrant locations throughout each of fourteen (14) separate systems. Each service area varied in size ranging from 150 to 4,000 fire hydrants. After each system was analyzed, the iWater data model was used for the geodatabase design and data collection began.
Once the GPS locations of over 50,000 valves and fire hydrants were captured, iWater was able to overlay the existing CAD drawing and As-builts. This enabled iWater to create a seamless geometric network of System Valves, Fire Hydrants, Water Mains, and Service Laterals.
With the GIS in place, iWater’s Department of Heath certified field crews were able to verify the status and  condition of each valve and fire hydrant in the system. By exercising valves and flushing hydrants, operations-specific details such as condition, ease/difficulty of operation, physical diameter, and operation comments were collected and validated. This type of data is critical for any water utility and is usually overlooked by GIS and engineering departments.
Now having a complete, operations-based GIS, GSWC is able to take full advantage by using infraMap software. This gives the district the ability to create maps and reports on demand, identify asset maintenance history, and view the operational status of each service area thoughout the company.
