How do we use GIS?
How do we use GIS?
Nearly every department at the MWA uses GIS in some way - mostly through our work management system
Customer Care
Field Services
Line Crews
Maintenance
Plant Operations
Engineering
CMMS sits on top of GIS & uses location information to:
Track ongoing work
Search completed work
Plan for future work
aka AMS: Asset Management System
Computerized Maintenance
Management System
How do we use GIS?
Combining GIS and AMS allows us to examine work in our system spatially ...
Which can lead to additional analysis - telling us more and more about our system
Valve Exercise Program
Leak Detection Program
Meter Location/Accounts Verification Program
Ongoing/Completed Projects
Valve Exercise Program
Ongoing project to exercise all valves on a rotating 2 year schedule
Ongoing Projects
Leak Detection Program
Actively seeking out leaks to repair
Ongoing Projects
Meter GPS/Accounts Verification Program
Locate, GPS, and Verify ALL Accounts
Completed Projects
Before
After
Intersection Cards
Water Data Correction Project

6. Future of GIS
What's Next?
Geometric Network allows us to answer simple questions about our network
Are these two points connected?
What's Next?
What happens when I close that valve?
... and what customers (and how many) will be effected?

Geodatabase (GDB)
GDB contains information tables as well as features (points, lines, polygons)
Geodatabase tables
So, what is a GIS?
polygons are shapes; they have area
points have neither
lines have length
