Interceptor Sequencing Study (ISS)

General Information

The Interceptor Sequencing Study (ISS) provides a high-level evaluation of interceptor alternatives and identifies interceptor alignment corridors, as well as anticipated capacity needs and interceptor pipe sizes. Development within the Sacramento Area Sewer District (SacSewer) service area will need to be coordinated with both Regional San and SacSewer. SacSewer’s long-term planning document is known as the Sewer System Capacity Plan (SCP), which can be found here. The ISS and SCP work together to lay out future sewer conveyance needs for the SacSewer service area. Amended portions of the SCP supersede the information in the ISS. Contact Regional San Development Services with any questions.
