• Significantly reduce Infiltration and Inflow (I&I) into the sewer system
• Restore structural integrity to the pipelines and manholes structures
• Reduce treatment and power costs by reducing excess water into the conveyance system

This effort will help to insure proper system operation. Our first target area concentrated on a part of the collection system that is more than 40 years old. The location is located east of Interstate 95 along the US 1 corridor in our downtown neighborhoods. This low lying area, the age of the system and capacity needed due to the plans for re-development, make it a prime target for start of this program.

Through our contractor's inspection methods, we adopted the National Association of Sewer Services Companies, (NASSCO) Pipeline Assessment Certification Program (PACP). Standard coding enables us to have our system properly evaluated objectively through a standardization of operation and maintenance observation codes and inspection forms. We received all video digitally in a standard MPEG format. Line inspection reports are viewed through a software program that allows us to view line and manhole inspection reports and link directly to the relevant video record from within the report.

Currently we have inspected over 900,000 feet of pipeline, (approx. 170 miles) ranging from 8" to 24" and approximately 5000 manholes. The process started in January 2007 and we are about to completed Phase V in April of 2010. Simultaneously we are coordinating repair phases as well. We have completed our third and fourth phases of repairs and have rehabilitated approx. 120,000 ft. of pipeline and approx. 900 Manhole structures.

The program has been successful in reducing I&I, and will continue to identify future areas of the collection system for inspection and evaluation as well as future repair phases based on our evaluation of the information collected.
