The City of Los Angeles (City) has been conducting advance planning for its 6,500-mile sewer system for decades using very conservative and technically sound engineering principles and tools. The City has embarked on an aggressive sewer renewal program to upgrade the aging sewer system and reduce Sanitary Sewer Overflows (SSOs) in all 218 secondary sewer basins of the wastewater system. In addition, the City is required to perform planning on the first 100 sewer basins over a 7-year period to meet the requirement under the Settlement Agreement (SA) entered into by the City with the USEPA, California Regional Water Quality Control Board, and the Santa Monica Baykeeper, in August 2004.

This paper will describe the innovative GIS-based tool that the City of Los Angeles is using to support sewer system rehabilitation and replacement planning activities. It will focus on the business process analysis and information system development performed by the City and consultants to create tools that automate and support efficient and effective sewer planning activities.
