Development of Performance Index for Stormwater Pipeline Infrastructure
Stormwater infrastructure asset management is becoming increasingly popular in the United States, with emergent government regulations and knowledge of the risk posed by deteriorating stormwater pipelines to the environment. Performance assessment of a stormwater pipe is an essential aspect of utility asset management plans. This paper presents a weighted factor framework to determine the performance of stormwater pipes. A list of about 50 parameters effecting the performance of stormwater pipelines was prepared based on literature review, study of existing stormwater asset management plans and feedback from utilities. The list was divided into essential and preferential parameters, due to a lack of readily available pipe parameters with utilities. A two-level hierarchical representation of degradation of stormwater pipeline infrastructure was developed, constituting five failure modules and the essential parameters. On the basis of survey replies obtained from ten utilities across the EPA regions, the essential parameters were combined into a performance index. The index is a scale of one to five, similar to National Association of Sewer Service Companies’ (NASSCO) Pipeline Assessment Certification Program (PACP) grading system. Furthermore, a prototype of the performance index was developed using real utility data.
