Use of GIS at TRWD
• Pipeline system consists of 180+ miles of underground largediameter (72”-108”) PCCP and steel pipes. Approximately 34,000 individual 20’-24’ pipe segments.
• Approximately 800 appurtenances (valves and manholes) and 700 cathodic protection test stations
• 15 full time field pipeline operators, and up to an additional 20-40 personnel assigned to pipeline during repairs/breaks
• Multiple TRWD Departmental Stakeholders:
- Engineering: Design, Integrity, Water Supply, Operations- Real Property: Permitting, Land Acquisition, Notifications- Western\Eastern Operations: Maintenance, Operations
TRWD Pipeline Operations Overview
• A centralized, enterprise geodatabase of pipeline features was very beneficial, but having “just” a database didn’t address all information management challenges.
• Business-driven desktop, web, and mobile applications were needed to bridge the information gap between field workforce and office personnel.

1) Cathodic Protection Features
2) Analyses of System Performance
Cathodic Protection Extension - TRWD FieldMapper
• Extension to the TRWD Mobile Field Mapping system that gives field personnel the ability to manage cathodic protection information
- Retrieve historical test station readings- Add/Modify test station readings- Create new test station features- Create new anode bed features

Raw Data from AquaCalc
Dale/Joe ExportsAquaCalc .CSVfile to Excel formatting data intocolumns.
Dale/Joe emailsExcel file to Courtney
Dale/Joe reviews data values, deleting bad values, adds Old Stationing Values & graphs to observe trends
Courtney reviews file & determines which pipeline & section the Pipe2Soil Readings relate to.
Courtney removes all ancillary data: 1) Lat,Lon2) UTC Time3) Altitude4) PDOP5) # Satellites6) Base ID7) Comment
Courtney preserves:1) Old Stationing Values2) Reading (not consistent)3)date of Reading
Courtney Runs Macros to:1) Round OLD Stationing Values to 10 foot intervals.2) Create consistent readings (remove “-”, add decimal, etc.)3) Joins Pipe2Soil readings to Master Excel Spreadsheet via Old Stationing Values, per Pipeline and Section
Courtney QC’s datato make sure that the Pipe2Soil readings are at the correct Old Stationing locations in the Excel Spreadsheet.
Courtney adds new Pipe2Soil readings to Master Graph in Excel Spreadsheet for Pipeline and Section
Complete workflow of information from field-to-office to decision-makers was inefficient
Ability to analyze and interpret P2S values from multiple surveys over multiple locations was cumbersome.

Pipe to Soil Data Import Tool
• Store and manage pipe to soil readings information in geodatabase tables instead of excel files
• Link readings to pipe to soil survey point locations (based on station numbers)

Brings the data out of the file cabinet “ and presents it in its “native” context –exploits its geographical properties
ConclusionGIS is greatly benefitting the management of the Pipeline System by enhancing the data collection, management, and coordination opportunities by District staff.
The ability of District Staff to utilize the TRWD FieldMapper to locate, document and redline pipeline system features is helping to keep the TRWD Pipeline model accurate, timely and cost effective.
The adoption and utilization of mainstream software development technology is driving down the cost of custom software development while continuing to provide very useful tools.
The use of GIS technology at TRWD continues to empower the organization, and optimize it’s operation of the TRWD Pipelines.
