Long-term capital improvement planning (CIP) and budgeting for aging infrastructure are a priority for municipal planners. As part of the CIP process, comprehensive pipe renewal programs (water/sewer/stormwater) are being developed that represent a significant capital investment for utilities. These pipe renewal programs are proactive system investments critical to protecting infrastructure by avoiding costly repairs and the potential harmful effects of deferred maintenance. Anticipating the rehabilitation or replacement of pipes and making the right decisions regarding which pipe to rehabilitate or replace, and when, may increase overall cost efficiency and users’ satisfaction. In a pipe renewal program, the first step is to perform a desktop analysis, where many factors that impact the service lives of pipelines (such as age, material, external and internal stresses, installation practices, joint type, soil corrosivity, corrosion protection, and traffic load) are considered for condition assessment and develop the pipeline replacement and rehabilitation (R&R) schedule. This presentation from a desktop analysis includes an example of using a computing tool, KANEW for economic assessment of water mains and development of long-term CIP. This case study uses KANEW to prepare a model to spatially display the condition assessment results by predicting the portion of the pipe network needing attention and the associated costs in any year in the future. The results are further modified using the anticipated funding allocation to prioritize areas for R&R within such investment. This novel long-term planning approach provides planners with reliable CIP data to manage buried linear assets for water, wastewater, and stormwater conveyance systems cost effectively and to users’ satisfaction.

Desktop Analysis of Buried Pipelines to Develop Renewal Program and Long-Term Capital Improvement Planning

Papers from sessions of Pipelines 2021, held virtually August 3–6, 2021. Sponsored by the Utility Engineering and Surveying Institute of ASCE. The conference provides a forum for pipeline engineers and practitioners from all around the world to share their experiences in meeting the challenges of today's pipeline infrastructure. This premier industry event has become the conference of choice for utility and pipeline owners, design and consulting engineers, contractors, manufacturers, suppliers, students, educators, researchers, and pipeline professionals. The conference includes surveying as it relates to pipeline and utility projects. This event will provide a dynamic and inspiring venue for participants to share and gain valuable knowledge related to planning, designing, constructing, renewing, operating, managing and maintaining the pipeline assets.
