The Problem Aging assets The City needs to extend the Service life of assets through a proper maintenance programs. A higher level of service expectations with a shrinking workforce. The DPS needs to create a Capital Improvement Plan? So many assets that is hard to prioritize what to maintain first. So many assets that it is hard to prioritize what to replace first. It is difficult to forecast and budget for projects? Emergency mentality instead of a preventative mentality. The institutional knowledge is retiring.

The Solution Asset Management Plan The International Infrastructure Management Manual defines an Asset Management Plan as A plan developed for the management of one or more infrastructure assets that combines multi-disciplinary management techniques (including technical & financial) over the life cycle of the asset in the most cost effective manner to provide a specific level of service.
Asset Management Plan Core Components 1) Asset Inventory 2) Level of Service 3) Critical Assets 4) Revenue Structure 5) Capital Improvements
Asset Inventory Information Needed What do I own? Data Collection (As Builds, Historic data, Current Project record keeping) Not easy when they are underground Old, inaccurate record keeping, and staff turnover Where are my assets? Mapping the asset and placing into a centralized database(gis) What is the condition of my assets? Condition Assessment (inspections of your assets) What is the remaining life of my Asset? What is the Manufacturers expected life of the asset. What environment is my asset in. What is the value of my Asset? Cost of Replacement
Condition Rating (Water System)
Level of Service (LOS) The Stakeholders Expectation of a System. Must follow the guidelines set by State and Federal Authorities Defining the LOS sets the goals for the utility. Examples Only 3 Sewer backups per household per year Every house in our system must have 30lbs of water pressure Every Water System Valve must be exercised 3 times per year. Every Storm Sewer must be cleaned every 3 years A potholes should be repaired within 24hrs 10 water main breaks a year When the LOS is higher more than likely your cost increases.
Critical Assets Certain types of asset may be critical in one location, but not so critical in another. A well pump serving a downtown location or a well pump in an industrial park that is under construction? How likely is it that the asset will fail? What is the consequence of failure?
Probability of Failure Multiplied by Consequence of Failure Water main constructed in 1950 One Service Repair in the past 15 years Probability of Failure is a 3 Need to be replaced in 10yrs Consequences of Failure is a 2 Water main services a now-abandoned industrial park. Probability of Failure * Consequences of Failure = Criticality Factor 3*2=6 The Criticality Factor is a 6
Typical Criticality Range 1-8 not considered Critical 9-16 important, but not critical Above 16 is considered critical
Other Factors to Criticality Redundancy reduces risk. A looped water main or a paralleled water main Criticality of an asset over time A new building or condominium was constructed. The Criticality factor must be reviewed periodically.
Revenue Structure How much should we charge? Operation Maintenance Replacement Capital Improvement Projects Dept Costs How much for water usage?
Capital Improvement Project Plan Forecast what asset you are going to replace 5-20 year plan Considerations Future/upcoming regulations Major asset replacement System expansion System Consolidation and Regionalization Improved Technology New Types of Meters
Background for TC s Utilities in GIS Started in the Engineering Department ESRI data model Transportation Water Storm Sewer Parcel data Piggybacked onto the county The County was instrumental in helping us get started with GIS and still is very helpful today. All data was Placed into an ArcSDE (Spatial Database Engine)
Building the GIS Transportation Collection through old documents and construction drawings Creation of a Pavement Management Plan 2006, inspired by the Transportation Asset Management Council Utilize PASER for Rating, which is collected every year Created a Feature Class
Building the GIS GPS Collection (Water, Sewer, and Storm) Manholes Water Valves Fire Hydrants Digitizing Engineering As-Built Drawings Entering into SDE
Good Start to Inventory Had parts of the inventory Location was good What we owned was good Created Cost Models Road Rehabilitation and Reconstruction Sewer Replacements Water Replacements Storm Replacements
Recently the Demand for Information Increased Due to the push toward an Asset Management Plan through new infrastructure policy. Inserting born on dates To help us define Remaining Service Life Water Mains life expectancy DPS Director wanted Dates on every piece of pipe in the City We came up with an Install Date (verified date) and Warranty Date (Best Guess)
Asset Management The Next level of Asset Management was Starting to come together. Had a DPS Director that believed in Asset Management DPS hired an Asset Management/GIS Analyst We are starting to take the inventory to the next level And then the SAW Grant
SAW Grant SAW stands for Storm water, Asset Management, and Wastewater. This is a new grant program administered by the Michigan Department of Environmental Quality (MDEQ) to help communities enhance their understanding of the physical condition of their wastewater and storm water infrastructure and to plan effectively for long-term capital improvements, operation, and maintenance of their sanitary and storm sewer systems. $2 Million in funding for: Asset Management Plan for Waste Water Asset Management Plan for Storm Water Management Plan for Storm Water
Waste Water Grant Goals Enhance GIS mapping of collection system Sewer cleaning and televising Manhole inspections Pump station evaluation Collection system evaluation and prioritization to identify maintenance and rehabilitation needs Flow metering and wet weather modeling Evaluate long-term infrastructure maintenance and capital needs Rate Study Total Program Cost: $1.00 million State Reimbursement: $819,000 Local Match: $181,000
Storm Water Grant Goals Enhance GIS mapping of drainage system Determine hydraulic bottlenecks and identify critical projects Sewer cleaning and televising Investment in hardware/software to enhance Asset Management Evaluate storm water quality issues and identify pollutionreducing enhancements Evaluate long-term infrastructure maintenance and capital needs Review storm water costs and revenue options Total Program Cost: $1.44 million State Reimbursement: $1.18 million Local Match: $263,000
Inventory Stage Year 1 of the 3yr Grant OHM is our Consultant Inspecting and Manholes utilizing NASSCO MACP Inspection standards. Contractors Wastewater wet weather monitoring CCTV Contractor cleaning and televising our Storm Sewers
SAW Grant Provided Funds to: Inventory our Storm Water and Waste Water Assets Purchase GIS Software and Hardware (GIS Investments) Purchase an Asset Management/Work Order Management System Help understand where we have worked and where we have the most problems/might be time for replacement Create an Advisory Board Determine level of service Create a funding mechanism to pay for a Storm Water Asset that has no funding

Two Assets Down After All Asset Management Plans are complete Transportation Storm water Water Waste Water Better decisions for all. Overlapping Asset Management Plans Find all the Roads Rated with a PASER of 3 or below and a utility with a Criticality Factor of 16 and above. One Project covering all assets.
Post Collection Realization First Stages Take Asset Management Philosophy and Utilize the Power of GIS to get an Output. Select by Location All Water Mains installed before 1947 All Sewer Gravity Mains installed before 1946 That fall in the area of a road that has the PASER rating below 4
With a Rating System and Overlay Techniques for Multiple Utilities
Traverse City s Asset Management Plan Every Asset in the City needs to have an Asset Management Plan Understand the Level of Service Better way to utilize money and budget for the future Increase the Service Life of an Asset through Maintenance Prioritize Maintenance for crews Create a solid CIP Help Stakeholders know what they have and where the Department would like to do work
