This document seeks to collect into one place current and new technologies about sewerage system design. The document organizes the information found in the 295 documents that were reviewed into six subject areas: Advanced Onsite Technologies; Alternative Wastewater Collection System Designs and Technologies; Gravity Sewer System Design and Technology; Infiltration Detection and Control Technologies; Sewer Construction/Rehabilitation Technologies; and Pipe Materials and Joints. Each of the six subject areas is further subdivided into three technology levels: Established Technologies; Proven Technologies; and Experimental and Foreign Technologies. The results are summarized in tabular form for easy review and comparison, followed by descriptions of each of the listed technologies. The descriptive section contains information on how the various designs and technologies work, their cost and performance, advantages and disadvantages, locations where the design or technology is in use, and identification of manufacturers of various technologies.
