Locating with GIS
ESRI Water Conference
January 29, 2018
Western Area Water Supply Authority
The Authority of the Western Area Water Supply Project
About the ProjectThe Western Area Water Supply Project utilizes a combination of Missouri River water treated
at the Williston Regional Water Treatment Plant and groundwater treated by the R&T Water
Supply Commerce Authority’s Water Treatment Plant in Ray. This water supply system meets
the needs of municipal, rural and industrial users in five northwestern North Dakota counties.
• Services Williston, Watford City, Ray, Tioga, Stanley, Wildrose, Crosby, Fortuna, Noonan,
Columbus and Ross
• Service area includes 5 counties: Burke, Divide, McKenzie, Mountrail and Williams
• Currently providing water to over 70,000 people
• Estimated to provide water to 160,000 people by 2038
Represents Five Water Entities:• Williams Rural Water District
• McKenzie County Water District
• City of Williston
• BDW Water System Association
• R&T Water Supply Association
Locates – and WAWSA
LOCATE: A formal request to
verify the locations of utilities –
particularly those underground –
before excavation
“811 Call Before You Dig!”
WAWSA maintains some 200 miles of
transmission water mains that convey
water to the rural and municipal
entities of northwestern North Dakota
All locate tracking is done via ND One
Call Concepts website. (Hasn’t
always been that convenient)
WAWSA’s Locate WorkfowISITE from OneCall Concepts
Times have changed
ND law requires all locating to be actively tracked AND updated ONLINE via ND
OneCall iSITE
PDF via Fax ISITE
WAWSA’s Locate WorkflowArcGIS Online Web Application
WAWSA’s Locate Workflow
ArcGIS Online Web Application
• Web App exhibits main transmissions, appurtenances, GPS points, and
other field-operations-related data
• Web Maps offer a more complete picture of operations and tasks – not just
reference points
• A visual representation of the locates would be quite beneficial for operators
in planning their day and delegating responsibilities
• BUT ArcGIS offers even more!
• With a little coding (and patience), locates can be updated on the ND
OneCall iSITE via the web application
• Essentially
• Edit/Update the “Status” field of Locate Feature Layer in ArcGIS Online
• Python Module queries the Feature Layer and posts those updates to
iSITE via web-scrapping techniques
• Operators able to update tickets from web application = More seamless workflow!
The Python Part
• Python comes with ArcGIS
Desktop
• ArcMap = Python 2.7
• ArcGIS Pro = Python 3
• Python offers a wide range of free,
accessible packages
• ArcPy – (only with ArcGIS) –
handles the geoprocessing
functionalities of ArcGIS (and
more)
• Python packages for WAWSA
Locate Workflow
• requests• HTTP access
• Beautifulsoup4• Web-scrapping
• ArcGIS API for Python• Well, everything else
The Python Part - Concept
STEP 11. Access iSITE
2. Scrape site for tickets
and details
STEP 21. Login into AGOL
2. Collect features
and attributes
STEP 3• Compare – ticket to ticket -
the feature attributes (AGOL)
with ticket details (iSITE),
specifically the Status
STEP 4• Update ticket with
AGOL feature attributes
– Status – and post
those up into iSITE
The Final Product
The operator only needs to interact with the Web App – Python does the rest!
It’s cooler when you see it …
