  1. FACILITIES/SANITARY SURVEYS AS DESIGN TOOL Eric L. Matson, P.E. Indian Health Service

  2. The SFC Project Management Program (PMPro)

  3. Business as Usual • Planning officially begins when a project is funded • Notable quotes after project funding: • “How did this get funded!” • “What can we do with this funding?” • “How many homes do we have out there anyway?” • “We’re going to need more funding to build that” • “That’s not federal trust property.” • “Who developed this cost estimate?”

  4. Business as Usual • O&M considerations addressed at completion of construction • Notable quotes after construction completion: • “Might as well weld the door shut. Might last longer that way.” • “No one at Tribe capable of operating this.” • “Not sure how Tribe is going to afford operation when things start to break.” • “Why did we build such a complicated system?” • “Wish we had time to provide as-builts.” • “I guess this binder of manufacturers’ submittals is the O&M manual.” • “What type of training is the contractor going to provide?” • “How is the tribe going to fund operator training?” • “SDS is O&M by replacement. We’ll be back in 10 years.”

  5. Business Using PMPro PMPro Equation #1 PDP + EX = EPR • Planning begins prior to project listing • Data & system/utility knowledge through sanitary surveys Project Development Planning & Design Construction Documents Construction Closeout

  6. 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

  7. 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

  8. Goals of EPA Sanitary Survey • Evaluate 8 elements of water systems • Source • Treatment • Distribution system • Finished water storage • Pumps/Pumping facilities and controls • Monitoring/Reporting/Data verification • Water system management • Operator compliance with State/EPA

  9. 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

  10. 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

  11. Improved IHS STARS Data System • 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

  12. Using ESRI ArcView/ArcReader on the Navajo DSFC DE-OM Meeting April 2012

  13. 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.

  14. 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

  15. Land Status layer helps determine that home is in Allotment # 1880 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

  16. Zoomed out view shows home in relation to the existing (green) waterline and close to SDS waterline SDS-NM17448-0104

  17. Home added to SDS Project in Attribute Table

  18. Maps and namelists can be easily be printed to submit for SDS

  19. 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

  20. View Home Details using Hyperlink

  21. View Waterline Profiles using Hyperlink

  22. View Well Details using Hyperlink

  23. 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

  24. HITS Initiative Community – AK CHIN

  25. HITS Initiative

  26. HITS Initiative

  27. District Engineer/O&M Meeting • 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. • Future Vision Element Teams • GIS Development • Asset inventory • Design life • Design tool (ex. hydraulic modeling platform) • OMDS Development • Asset management • Utility development & evaluation (ex. SDS O&M Score)

  28. WebEHRS, SDS, PDS, and OMDS systems should work together to archive conceptual, ongoing, and installed infrastructure Sanitary Survey Data WebEHRS WebPDS Designed & funded asset WebSDS Proposed asset OMDS As-built asset Proposed additional OMDS information

  29. Drivers for Change 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
