GIS for managing public utilities in the City of Frisco – A demonstration by Usha Eleswarapu

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

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

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

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

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

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

Objective 2: Build a customer database for sewer and water service Customer ID Customer Database Water Service Customer ID

Objective 2: Build a customer database for sewer and water service

Objective 3: Build an infrastructure maintenance database for storm, sewer and water pipelines → Stormlines Maintenance Database → Sewerlines Maintenance Database → Maintenance Database Waterlines

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

Objective 4: Create a geocoding service for houses

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

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

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

Objective 5: Create network flow for stormlines Sink

Objective 5: Create network flow for sewerlines Sink

Objective 5: Create network flow for waterlines Source

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.

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
