2. Overview
 The Prince William
County Service
Authority is a
wastewater and
water utility serving
approximately
360,000 people.
 Undertook a large-
scale GIS Centric
Information
Technology
Infrastructure review
and upgrade over 3
years

3. Autodesk MapGuide System
 Had been using Autodesk CAD technology for last 10 years
(Autodesk MapGuide Enterprise)
 GIS production done in CAD environment (WaterMap)
 CAD application wrote data to Oracle Spatial
 Oracle Spatial data served to SA Web Portal

9. PWCSA - Parcel Search

10. Customer Service Systems
– Spatial Search & Quick Information Retrievals
Selected parcels
and related
customer
information

11. Operations and Maintenance (O&M)
Work Order Mapping & Analysis
 Search by WO
activity, date range,
spatial extent-
Subdivisions,
sewersheds, service
levels etc.
 Vulnerability of
Critical
Infrastructure.
 Track labor &
indirect costs,
overall maintenance
costs across
sewersheds

12. PWCSA – Work Order Search
Selected
work order

13. Operations and Maintenance (O&M) –
Condition Assessment
 Direct Link to Asset
Management System
main condition
ranking
 Sewer Main
Condition Ranking

14. Consumption Data Analysis & Meter Data
 Consumption Data
from Customer
Service – Billing
 Statistical Estimates,
Engineering Analysis
and Planning by
aggregating usage
data for parcels
within specific
subdivisions, service
levels etc.
 Detection of
anomalies and
aberrations for leak
detection, illegal
usage etc.

15. Customer - Service Requests
Customer Service Call Mapping Online Customer Service Requests:
 Map customer issues dynamically & generate service orders
 Improved response time
 Mapping and visualization of complaints/issues/resolution
over time
 Significant improvements with level of Service

16. Customer Service - Service Outage
Notification and Real-time Work Order
Status for Affected Parcels

17. Improved Field Communication
Field Notation Mapping:
 Quick corrections to
GIS data errors
 Easily communicate
location and specifics
of issues
Work Order Tracking
 Dynamic views of where
crews are working and
where issues are within
the utility
 Informative Customer
Service response to
outages and other issues

18. Document Management - Markers
Markers are used to attach documents to spatial locations throughout the
county. They are automatically grouped in units to provide for easier review of
available markers without the need to zoom to large scales.

19. Document Management
– Metadata / Project Plan Information
