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 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
