Abstract:

The City of Las Vegas Downtown Interceptor Sewer was constructed in the early 1980's and consists of approximately 23,000 linear feet of 42- to 54-inch unlined reinforced concrete pipe (RCP). The Interceptor is a critical asset for the City of Las Vegas. The City initiated a contract for a fast-track condition assessment and rehabilitation design in one-half the normal design time to reduce the risk of a sewer collapse.

Based on risk, a rehabilitation strategy was developed for the final design that included, not only the Grade 4 and 5 areas, but adjacent areas that would be difficult to rehabilitate in the future due to large traffic volumes and/or business disruption.

This paper presents the project steps to complete the condition assessment and design on an accelerated schedule, while ensuring that limited City construction funds were only spent for rehabilitation in high-risk areas.
