Abstract:

Wastewater service providers continuously strive to carry out projects cheaper and faster. The Sewerage and Water Board of New Orleans, through its Sewer System Evaluation and Rehabilitation Program, has developed an innovative process for manhole condition assessment and rehabilitation method selection. This paper explores the steps taken by the Sewerage and Water Board to accomplish these efforts, including the development of a standardized inspection process and a computerized tool for selecting the rehabilitation method. This process consists of standardized data collection, computerized decision-making and implementation of appropriate rehabilitation methods to quickly and effectively address manhole rehabilitation needs. The authors show how implementation of these measures has made tackling the rehabilitation of New Orleans' 28,000 sanitary sewer manholes an attainable and feasible task.
