CONDITION ASSESSMENTofPinery Water and Wastewater District’s Systemfor GASB 34/35 and CMOM
Pinery Water and Wastewater District Charles J. Krogh, Paul Makowski, Kevin Clark Presented by Farnsworth Group Doug Barker, GIS Specialist Ceila Rethamel, P.E. Jim Pardy, P.E.
PINERY INFORMATION • Pinery Water and Wastewater District - located south of Parker • Staff with 20+ years of experience • Facilities range in age from 30 years to brand new • Primarily residential users with a golf course
INTRODUCTION • Pinery wants to more efficiently manage repairs, maintenance, and replacement of facilities due to upcoming regulations (GASB 34 & CMOM)
INTRODUCTION (cont’d) • Pinery has data and information in various sources • paper as-builts • CAD files • staff’s extensive knowledge • records: breaks, billing, metering
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
TOPICS OF DISCUSSION • Geographic Information System (GIS) • Doug Barker, GIS Specialist • Hydraulic Modeling • Ceila Rethamel, P.E. • Engineering Condition Assessment • Jim Pardy, P.E.
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
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
Hydraulic Modeling • Tool used to locate • bottlenecks • low pressure areas • functionally obsolete piping
Software Evaluation WaterCAD (proprietary software) vs. EPANet (freeware) EPANet chosen: • freeware • ArcView extension to extract *.inp files • water quality modeling
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
Demand Analysis • Allowed more time for analysis of demands and usage
Adding Pipe to the Model • Fairly simple with GIS and EPANet • Pipes have been added several times for proposed development • Updated the background map
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
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
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)
Facility Condition Index (FCI) • objective tool used to track an element of infrastructure • general forecast of what type of reserves need to be available to maintain or improve The FCI is commonly defined Deficiencies FCI= -------------------------------------- Current Replacement Value FCI<5% Good Condition FCI 5%-10% Fair Condition FCI>10% Poor Condition
Replacement Values and Deficiencies Values • Length of pipe from the GIS database • Assign costs
Replacement Values and Deficiencies Values (cont’d) Assign a percentage of the replacement cost to each of the ECA categories: 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
Replacement Values and Deficiencies Values(cont’d) • Deficiencies $102,162 • FCI= -------------------------------------- = --------------- = 10% Fair Conditions • Current Replacement Value $1,053,435
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
CONCLUSION (cont’d) • The Pinery will use the GIS maps for: • locates • any projects related to the system • queries
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
CONCLUSION (cont’d) • 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
