1. GIS for managing public utilities in the City of Frisco – A demonstrationby
Usha Eleswarapu

2. Project Aims
To demonstrate the use of GIS in managing public utilities such as storm, sewer and water
To identify some applications of such data in city management

3. Objectives
Design and create a geodatabase for parcel, storm, sewer and water data
Build a customer database for sewer and water service
Build an infrastructure maintenance database for storm, sewer and water pipelines

4. Objectives contd.
Create a geocoding service for houses and street intersections
Create networks for storm, sewer and water flows

5. Study Area: Subdivision of Hunter’s Creek Phase 5, City of Frisco

6. Objective 1: Design and create a geodatabase
for parcel, storm, sewer and water data

11. Objective 3: Build an infrastructure maintenance database for storm, sewer and water pipelines

12. Objective 4: Create a geocoding service for houses

13. Objective 4: Create a geocoding service for street intersections↓
Accident History

14. Objective 5: Create network flows for storm, sewer and water
Network connectivity rules makes editing easier
A number of simple and advanced network analysis solvers can be used
Tasks such as establishing flow direction, redirecting flow, finding facilities that serve a set of customers

15. Objective 5: Create network flows for storm, sewer and water contd.
Use of weights such as pipe diameter to calculate pressure by solvers
Use of Netflags and barriers by solvers
Trace solvers such as upstream trace, downstream trace, isolation trace and path trace

16. Objective 5: Create network flow for stormlines

19. Conclusions
Geodatabase design is critical in effective GIS implementation
Geodatabase format has advantages such as more accurate editing, a uniform repository of data and more intelligent features
Applications such as linking to infrastructure maintenance and customer databases are useful in tracking problems with storm, sewer or water lines, utility billing and connections, etc.

20. Conclusions contd…
Geocoding service helps in landowner notifications and directing repair crews
Network flows help in maintaining topological integrity and in tasks such as establishing flow direction, isolating leaks and calculating pressure or head
