AWWA/WEF Utility Management Conference 2013 | Year: 2013

This paper outlines a recent research project to develop a standard method for capturing the total cost of drinking water and wastewater pipeline condition assessment and renewal engineering projects in an automated, web-based manner. The efforts were part of the WATERiD project, funded by the USEPA and WERF. WATERiD was developed as the de-facto national database to capture and share vital information on water industry practices regarding pipeline asset management. This paper summarizes the methodology and results observed including direct costs of a few commonplace technologies in the industry, supplementary direct costs (traffic control, inspection, etc.), and a novel look at societal costs such as traffic delays and business disruption. The data came from nearly 80 drinking water and wastewater utilities of varying size and location in the US and amounted to nearly 600 examples. The results present apparent direct cost drivers and quantified societal costs that will enhance utilities' financial decision making in asset management. © 2013 American Water Works Association.

Some of the political aspects associated with corrosion and pipe repair, replacement, and rehabilitation, are discussed. The political focus is mainly on the cost of pipe as the major factor in the decision-making process, especially when taxpayers and ratepayers are taken into consideration. As the risks of failure in aging pipes continue to rise, utility managers must better educate their boards and councils on how to set realistic expectations with their customers. The US Environmental Protection Agency's newly published report 'Decision Support for Renewal of Wastewater Collection and Water Distribution Systems' provide the overall renewal framework of asset management planning. In case of water main breaks, elected officials have to communicate with the public, and utility managers should take this opportunity to provide backup and support for these officials.

Developing an affordable utility capital plan with declining revenues during an economic downturn is like playing the Parker Brothers' game of Jenga, in which players remove a block from a tower and balance it on top, stretching it taller and making it increasingly unstable as the game progresses. Utility managers are being challenged to develop comprehensive capital plans to replace aging infrastructure, then chop out sections and extend the required work over a longer time frame. This project-preprioritizing effort is driven by budget and revenue constraints and supported by asset management criticality analysis. The strategy of performing condition assessment activities and then engaging in a long-term monitoring program can provide a substantially lower cost in the earlier years and may provide an overall reduction of replacement costs when failure curves are projected and deterioration is monitored in real time for each pipe segment. Condition assessment and inspections are not enough to prevent catastrophic failure.

Building bridges requires a careful planning and coordination between engineering and financial disciplines and a knowledge of force, mass, stress, and stability of the structure. Building a bridge requires measuring the distance to be spanned and determine the design of the central truss, installing foundation piers so they provide vertical support for the overall span, and building cantilever arms toward the center of the span and also toward the supporting foundations at the ends of the bridge and attach them to the support piers. The maintenance activities and records that are part of a computerized maintenance management system (CMMS) and work order system are the most basic components of a maintenance program. Condition assessment establishes the current condition of assets as a means of prioritizing and forecasting maintenance and rehabilitation efforts.

Polyvinyl chloride (PVC) pipe meets the challenges and costs associated with the aging water infrastructure crisis for water and wastewater systems. To understand the nature and scope of the emerging infrastructure challenge, AWWA undertook an analysis of 20 US utilities. The analysis projects future investment needs for pipe replacement in these 20 utilities and provides a forecast called a Nessie curve. The Nessie curve is a graph of the annual replacement needs for a particular utility, based on when pipes were installed and how long they are expected to last in that utility before it becomes economically efficient to replace them. To assist utilities, asset management firms are regularly applying low-cost PVC slip lining as an intermediate renewal solution and extending the pipeline life by a minimum 40 years. PVC, with 75 to 95 years of minimum expected life and low maintenance, is then typically selected to achieve overall lower life-cycle cost projections.

Geographic information system (GIS) centric public asset management has a foundation that standardizes data and allows interoperability, providing users the capability to reuse, coordinate, and share information in an efficient and effective manner. The city of St. Louis, Mo., is using a GIS-centric management solution for online citizen service requests that has substantially improved work flow and communication to track all citizen service requests. In the city of New Haven, Conn., this social platform for exchanging information with local governments is helping the city respond to a larger number of resident concerns with fewer work hours. In June 2010, a New Work Item Proposal on Asset Management was reviewed at an International Organization for Standardization (ISO) preliminary meeting, which approved the formation of Planning Committee 251.
