Going beyond NASSCO PACP Guidelines for Sewer Condition Assessment and Criticality Prioritization
Abstract Condition assessment (CA) is crucial for effective asset management of sanitary and storm sewers, enabling municipalities and utilities to prioritize repairs, reduce costly emergency fixes, and minimize environmental impacts. A key element is the systematic data collection on structural and operational defects. Multi-sensory inspection (MSI) platforms, typically using CCTV cameras, capture high-resolution images of […]
Condition Assessment Program for 46-Year-Old Sanitary Forcemains in the Canadian Arctic Region
Abstract Assessing the structural integrity and hydraulic performance of buried sanitary conveyance systems is essential for municipalities to prioritize their repairs, prevent costly emergencies, and reduce public and environmental impacts. This work presents a condition assessment program for two forcemains: a 2.3-km long 560-mm pipeline and a 5-km long 600-mm pipeline, both welded steel pipes […]
Condition-Based and Risk-Based Assessment Approach for Large Diameter Pipelines Used In Conveyance of Wastewater
Abstract Implementation of advanced and fit-for-purpose asset management strategies requires careful and thoughtful assessment of the physical conditions of buried, large diameter pipelines used within wastewater collection and conveyance systems. Knowledge of the structural integrity and hydraulic performance of these critical assets is therefore crucial. It provides guidance to municipalities and utilities on (i) prioritizing […]
Innovative Condition Assessment Techniques for Aging Sanitary Pressured Pipelines in Extreme Climates
Abstract Knowledge of the ‘as-is’ structural integrity and hydraulic performance of buried sanitary conveyance systems is crucial and provides guidance to municipalities on (i) prioritizing repair and replacement projects, (ii) avoiding costly and disruptive emergency repairs and (iii) importantly, minimizing public and environmental impacts. The current work reports the development and implementation of a systematic […]
