These standards and specifications are for use with the design and construction of gravity sanitary sewer lines within new developments.  Some projects may require specific specification be created by the developer's engineer depending on size, location, depth or other factors which the District's standard specifications do not cover.  The developer's engineer must consult with the District on each project to determine if project-specific specifications are required.
