5
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference INTRODUCTION Pinery wants to more efficiently manage repairs, maintenance, and replacement of facilities due to upcoming regulations (GASB 34 & CMOM)
6
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference INTRODUCTION (cont’d) Pinery has data and information in various sources paper as-builts CAD files staff’s extensive knowledge records: breaks, billing, metering
7
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference INTRODUCTION (cont’d) Pinery hired Farnsworth Group to: Compile data in central location Complete hydraulic analysis Develop condition assessment Efficiently link different tools and software to the database

Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference TOPICS OF DISCUSSION Geographic Information System (GIS) Doug Barker, GIS Specialist Hydraulic Modeling Ceila Rethamel, P.E. Engineering Condition Assessment Jim Pardy, P.E.
9
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference Geographic Information System Uses Compile inventory of assets into digital format Prepare data for hydraulic modeling software Prepare data for condition assessment Create 11x17 field atlas for staff use Future use with billing and/or maintenance software Support GASB 34 and CMOM compliance
10
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference Geographic Information System Benefits Efficient access to information Hydraulic modeling set-up much easier Condition assessment performed with our existing GIS software Excellent cartographic/presentation tool Potential to link the GIS to other software

18
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference Hydraulic Modeling Tool used to locate bottlenecks low pressure areas functionally obsolete piping
19
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference Software Evaluation WaterCAD (proprietary software) vs. EPANet (freeware) EPANet chosen: freeware ArcView extension to extract *.inp files water quality modeling
20
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference Physical Model Coordinated data entry into GIS database to ensure information works for the physical model. Items left to add or check are: directionality of PRVs and pumps tank data pump data controls demands Converts to PRV or pump Will not convert to a PRV or pump
21
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference Demand Analysis Allowed more time for analysis of demands and usage
22
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference Adding Pipe to the Model Fairly simple with GIS and EPANet Pipes have been added several times for proposed development Updated the background map
23
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference Storing Hydraulic Results Store results in the GIS - track scenario maps of pipe velocity or node pressure tie pressures to addresses use results in the condition assessment

26
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference Asset Condition
27
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference Asset Condition Created asset condition standards and quality thresholds Prepared current condition assessment report Create a Facility Condition Index Asset Condition will help meet requirements of GASB 34 and CMOM
28
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference Engineering Condition Assessment (ECA) 1=Excellent Condition 2=Good Condition 3=Acceptable 4=Unacceptable 5=No Longer Serviceable A score of: 5-14 - Adequate (Green) 15-24 - Degraded (Yellow) >24 - Unsatisfactory (Red)
29

30
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference Facility Condition Index (FCI) The FCI is commonly defined Deficiencies FCI= -------------------------------------- Current Replacement Value FCI<5%Good Condition FCI 5%-10%Fair Condition FCI>10%Poor Condition objective tool used to track an element of infrastructure general forecast of what type of reserves need to be available to maintain or improve
31
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference Replacement Values and Deficiencies Values Length of pipe from the GIS database Assign costs
32
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference Replacement Values and Deficiencies Values (cont’d) Adequate – reserve of 2% of the total replacement cost Degraded –reserve of 20% of the total replacement cost Unsatisfactory - reserve of 100% of the total replacement cost Assign a percentage of the replacement cost to each of the ECA categories:
33
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference Replacement Values and Deficiencies Values (cont’d) Deficiencies $102,162 FCI= -------------------------------------- = --------------- = 10% Fair Conditions Current Replacement Value $1,053,435
34
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference CONCLUSION Farnsworth Group helped the Pinery develop new tools to manage repairs, maintenance, and replacement of their facilities. The tools included: GIS hydraulic model Engineering Condition Assessment and Facility Condition Index
35
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference The Pinery will use the GIS maps for: locates any projects related to the system queries CONCLUSION (cont’d)
36
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference CONCLUSION (cont’d) The Pinery will use the hydraulic model to: assist with new development decisions support their cases with developers assist with operation decisions system flushing water quality issues
37
Farnsworth GROUP Rocky Mountain Section - American Water Works Association 2002 Joint Annual Conference The Pinery will use the ECA/FCI to: communicate to customers and board members why reserve funds are needed how funds are going to be spent on various projects track conditions help meet requirements of GASB 34 and CMOM CONCLUSION (cont’d)
