Asset Management Planning and Reporting Options for Water Utilities
Asset management is the best method for prioritizing short-, medium-, and long-term asset rehabilitation and replacement expenditures of a water utility's pipelines and other infrastructure assets. What tools are available for beginning an asset management program? Is there a point of diminishing returns for your efforts and expenditures in gathering the data needed by an asset management program? This study will help you answer those questions. The purpose of this study is to help any size utility to understand the benefits and drawbacks of various asset management strategies, from basic to high end. It will help you understand the data needs of different asset management programs and the types of information you can expect to get out of such programs. It will help you determine the appropriate performance measures, asset groupings, and evaluation framework for your utility's assets. The included CD-ROM contains deep insights gained by participating utilities in this study. This research report compares side-by-side the reports generated by basic and higher-level asset management programs. Three increasingly sophisticated (and increasingly expensive) asset management strategies are compared side by side. (1) Basic Option, in which major assets are evaluated for service life, to estimate renewal expenditures. (2) High-End Option, in which key performance measures of individual and grouped assets are assigned scores to aid in replacement decision-making. (3) Strategic Option, which combines elements of basic and high-end and adds other performance criteria. 2006 - 160 pp. ISBN 1583214119; Catalog No. 91095 $$ Order Now

Costs of Infrastructure Failure
When a water main goes down, a utility's direct costs for labor and materials to return that main to service are relatively easy to estimate. But what about the hidden costs resulting from a water infrastructure failure? How can you assign a cost to customer inconvenience, traffic delays, police and emergency services, lost economic activity, diminished fire-fighting capacity, and human injury? Such "social" costs incurred by water infrastructure failure are very real, but because of their nature, they have been impossible to estimate accurately. Until now. This AWWA Research Foundation report and modeling software provides water system managers with the first comprehensive method for quantifying social costs of water infrastructure downtime. For the first time, it is possible to estimate not only the direct utility costs of a water infrastructure failure but also response and recovery costs to other parties or city departments, costs of damage to property, costs of illness caused by the failure, and even the dollar cost of traffic delays and customer inconvenience. 2002 - Softbound - 92 pp. ISBN 1583212647; Catalog No. 90918 $$ Order Now

Water Infrastructure at a Turning Point: The Road to Sustainable Asset Management
This report will give you a foundational knowledge of the issues surrounding our aging water infrastructure and offer you a common sense, affordable approach to managing your own water infrastructure assets. There has been much discussion about the deteriorating physical condition of the US water infrastructure. The expense and effort required to replace is so daunting it seems impossible to accomplish. The water infrastructure is aging and costing more and more each year to maintain. Where does a water utility begin the process of rehabilitation and replacement of an entire water system? Our water and wastewater infrastructure was built over generations and can be rebuilt at an affordable pace if we make smart decisions now. The task for our generation is to initiate and manage a modern, methodical, and sustainable asset renewal process. The book comes with a ready-to-use Microsoft PowerPoint slide presentation on CD. Titled "Water Infrastructure at a Turning Point," the presentation illustrates major points about water infrastructure replacement and asset management in a quick and simple manner. It is perfect for presenting to utility employees, city councils, and other groups who have an interest in city water infrastructure needs. 2006 - Softbound - 52 pp. ISBN 1583214224; Catalog No. 20615 $$ Order Now 

Water Treatment Plant Infrastructure Assessment Manager, Second Edition
This CD-ROM program provides water utility managers a precise method to evaluate the condition of water treatment plant infrastructure and assign priority ratings for capital improvements. This program provides an organized way to gather and record information about the physical condition of the total infrastructure - the systems, subsystems, equipment, and buildings - of a drinking water treatment facility. The software produces numerical scores rating the condition of each treatment plant infrastructure system and component and the vulnerability of the treatment plant relative to the condition of each component. This enables the manager to both evaluate the condition of systems and equipment and prioritize capital improvements. This software puts the manager in control of treatment plant infrastructure, by providing information on the condition of every system, subsystem, and piece of equipment in the treatment plant. It gives managers the information to prioritize infrastructure improvements and make best use of funds. 2003 - CD-ROM ISBN 1583212949; Catalog No. 90843 $$ Order Now

Measures:

Asset inventory
Description:
This measure gauges a utility's efforts to assess assets and asset conditions, as the first steps towards building a comprehensive asset management program.

Example calculations: 

  • Inventory coverage (percent): 100 X (total number of critical assets inventoried within a reasonable period of time (e.g., 5-10 years) / total number of critical assets). A utility will need to first define what it considers to be a critical asset and a complete inventory will involve understanding the following for each:

    • Age and location;

    • Asset size and/or capacity;

    • Valuation data (e.g., original and replacement cost);

    • Installation date and expected service life;

    • Maintenance and performance history; and

    • Construction materials and recommended maintenance practices.1 

     
  • Condition assessment coverage (percent): 100 X (total number of critical assets with condition assessed and categorized into condition categories within a reasonable period of time (e.g., 5-10 years) / total number of critical assets). Condition categories could include: unacceptable, improvement needed, adequate, good, and excellent to reflect expected service levels and accepted risks.

Asset (system) renewal/replacement
Description:
This measure assesses asset renewal/replacement rates over time. The measure should reflect utility targets, which will vary depending on each utility's determinations of acceptable risks for different asset classes. Decisions on asset replacement typically factor in internally agreed-upon risks and objectives, which may differ by asset class and other considerations. For instance, a utility may decide to run certain assets to failure based on benefit-cost analysis.

Example calculations: 

  • Asset renewal/replacement rate (percent): 100 X (total number of assets replaced per year for each asset class / total number of assets in each asset class). For example, a two percent per year replacement target (50-year renewal) for a particular asset class could be identified as the basis for performance monitoring.
    - or -

  • Asset (system) renewal/replacement rate: 100 X (total actual expenditures or total amount of funds reserved for renewal and replacement for each asset group / total present worth for renewal and replacement needs for each asset group). This is a QualServe Indicator.2 

Water distribution/collection system integrity
Description:
For drinking water utilities, this measure quantifies the number of pipeline leaks and breaks. Distribution system integrity has importance for health, customer service, operational, and asset management reasons. For wastewater utilities, this measure examines the frequency of collection system failures. When tracked over time, a utility can evaluate whether its failure rate is decreasing, stable, or increasing. When data are maintained to characterize failures by pipe type and age, type of failure, and cost of repairs, decisions regarding routine maintenance and replacement/renewals can be better made.3 

Example calculation (drinking water utilities): 

  • Leakage and breakage frequency rate (percent): 100 X ((total number of leaks + total number of breaks) / total miles of distribution piping per year). (Note: leaks and breaks are distinctly different events.) This is a QualServe Indicator.4 

Example calculation (wastewater utilities):

  • Collection system failure rate (percent): 100 X (total number of collection system failures / total miles of collection system piping per year). This is a QualServe Indicator.5 

Planned maintenance
Description:
Planned maintenance includes both preventive and predictive maintenance. Preventive maintenance is performed according to a predetermined schedule rather than in response to failure. Predictive maintenance is initiated when signals indicate that maintenance is due. All other maintenance is categorized as corrective or reactive.6 

Example calculations:
This measure can be measured in different ways. Calculating costs may be preferable to encourage business decisions based on total cost; however, the reliability of costs is uncertain. Hours are likely to be less variable than costs, but not all utilities track hours. Thus, cost and hours ratios are desirable, where possible.

  • Planned maintenance ratio by hours (percent): 100 X (hours of planned maintenance / (hours of planned + corrective maintenance)). This is a QualServe Indicator.7 

  • Planned maintenance ratio by cost (percent): 100 X (cost of planned maintenance / (cost of planned + corrective maintenance)). This is a QualServe Indicator.8
