FACILITIES/SANITARY SURVEYS AS DESIGN TOOL

The SFC
Project Management
Program
(PMPro)
• Planning officially begins when a project is funded
• Notable quotes after project funding:o “How did this get funded!”o “What can we do with this funding?”o “How many homes do we have out there anyway?”o “We’re going to need more funding to build that”o “That’s not federal trust property.”o “Who developed this cost estimate?”
Business as Usual
• O&M considerations addressed at completion of construction
• Notable quotes after construction completion:o “Might as well weld the door shut. Might last longer that way.”o “No one at Tribe capable of operating this.”o “Not sure how Tribe is going to afford operation when things start to break.”o “Why did we build such a complicated system?”o “Wish we had time to provide as-builts.”o “I guess this binder of manufacturers’ submittals is the O&M manual.”o “What type of training is the contractor going to provide?”o “How is the tribe going to fund operator training?”o “SDS is O&M by replacement. We’ll be back in 10 years.”
Business as Usual
• Planning begins prior to project listing• Data & system/utility knowledge through sanitary
surveys

IHS Survey Definition
Sanitation Facilities include water, sewer, and solid waste
Onsite in-depth assessment of facilities, equipment, operation and maintenance (O&M) of the system
Goals of the IHS Survey Identify system deficiencies and plan for
improvement (SDS) Identify problems affecting quality of water
or environment Gather data for designs, preliminary
engineering reports/master plans Identify tribes technical, financial,
managerial capacity and training needs Facilities inventory (IHS data systems) IHS staff training
Goals of EPA Sanitary Survey Evaluate 8 elements of water systems

Hypothetical Project Existing 100,000 gallon storage tank
serving public water system (PWS) is deteriorated and in need of replacement. What data must be collected in order to design new storage tank
Data for Storage Tank Design Number of service connections (i.e.
demand) Existing storage capacity Existing source water capacity/production Fire flow requirement Existing distribution system capacity for
fire flow delivery (requires hydraulic model which requires composite dwg)
Existing distribution system pressures Communities long term development plan Tribes capacity to operate
OMDS & GIS Development• Visual representation of asset inventory
w/links and attribute tables• Hydraulic modeling platform• Sanitary survey/EPR design info.• As-built scans, well logs• SDS O&M score• Utility rate studies/evaluations• O&M manuals
Improved IHS STARS Data System
Using ESRI ArcView/ArcReader on the
NavajoDSFC DE-OM Meeting
April 2012
Where in the world is that waterline, anyway?
The NTUA contracted the GIS mapping of all of the water utilities on the Navajo Reservation, including waterline, tanks, wells, valves, etc. The IHS has been using that valuable data for hydraulic modeling and other important project-related tasks.
ArcView as a Planning and Design Tool
• Locating nearest existing or planned waterline• Identifying nearby homes• Avoiding right-of-way obstacles• Locating other existing utilities• Storing data on existing surveying control
points• ArcPad on a mobile device allows all this to be
done in the field
Homeowner submits application - site visit completed and GPS reading entered into ArcView
Topo Map from ESRI online support superimposed with aerial image to view home and section lines
Land Status layer helps determine that home is in Allotment # 1880
Zoomed out view shows home in relation to the existing (green) waterline and close to SDS waterline SDS-NM17448-0104
Home added to SDS Project in Attribute Table
Maps and namelists can be easily be printed to submit for SDS
ArcView as an Operation and Maintenance Tool
• One centralized source for all as-built data that can be easily transmitted and shared
• Hyperlinks allow storage of project as-builts with pertinent design data
• Changes in project status automatically displayed based on changes to attribute values
• ArcPad on a mobile device allows operators/engineers/technicians to access data on any facility while at the site
View Home Details using Hyperlink
View Waterline Profiles using Hyperlink
View Well Details using Hyperlink
ArcView provides:
• An electronic, georeferenced “base map” alternative to cumbersome mylar and paper copies of as-builts
• A forum to integrate the Tribe’s GIS data with our hydraulic models and survey data
• A tool to determine the easiest way to extend services to a home by identifying the nearest existing, funded (PDS) or proposed (SDS) waterline
• Coordinate information, based on any system, for waterline tapping or other permits
• A way to store and geographically organize project as-builts

If the sanitation facilities we construct do not meet their design life how does that affect our ability to provide sanitation facility access to all homes.

Proposed asset
WebEHRS, SDS, PDS, and OMDS systems should work together to archive
conceptual, ongoing, and installed infrastructure
OMDS
As-built asset
Sanitary Survey Data WebEHRS
Proposed additional OMDS information
Seemless conversion of dwg. files to shape files GPS surveying more prevalent User friendly data (ex. STARS) systems Ensuring knowledge remains as people move on Increased reliance on data systems by multiple
agencies Decreasing construction funding resulting in focus on
sustainability
