Local Government Management of GIS Data for a Water Utility

Local Government Management of GIS Data

for a Water Utility

Marc Rhan

Water – How is it maintained?• Clean drinking water

• Water infrastructure is vitally important to everyone

• How is the data managed?

PROBLEMS

• GIS database for water line and components

• Costs to implement and maintain

• Standardized structure

• Manage utility assets

• Public notification

• Homeland Security

Objectives

• Assisting the Stakeholders with a final product

• Creating a standardized method of data creation and transfer

• Create a financial vehicle to facilitate updates as they occur with new development

•ESRI has developed a prototype water database format

ESRI model - Pump Attributes

ESRI model – Fittings

Process / manage data

• ESRI has developed a prototype water database format

• Modify existing database

• Migrate existing data

• Update data

• Authenticate data

• Publish data

Standardization

• Ordinances

• CADD standards

• Provide revenue stream / methodology to obtain data as it changes

• Implement methodology to merge CADD data

• Authenticate all data updates

With CADD – sorting through all the layers is difficult!No storage of intelligence for the data itself

As Built drawings - Engineering precision, GIS problems

Conclusions

• Client desire to develop database• Funding sources• Procedures to gather field changes and implement

changes to database• Standard methods• Authenticate changes• Make data / training available to client for

use in planning and maintenance
