It contains information useful to the average engineer in his or her everyday work, rather than findings that may be useful only occasionally or rarely. As often as practicable, the committee is under the direction of one or more of the Technical Divisions and Councils, and the product evolved has been subjected to review by the Executive Committee of the Division or Council.
As a step in the process of this review, proposed manuscripts are often brought before the members of the Technical Divisions and Councils for comment, which may serve as the basis for improvement. When published, each work shows the names of the committees by which it was compiled and indicates clearly the several processes through which it has passed in review, in order that its merit may be definitely understood. All such Manual or Report material of the Society would have been refereed in a manner approved by the Board Committee on Publications and would be bound, with applicable discussion, in books similar to past Manuals.
Numbering would be consecutive and would be a continuation of present Manual numbers. In some cases of reports of joint committees, bypassing of Journal publications may be authorized. The primary function of the Committee is to originate and produce, through appropriate subcommittees, special publications dealing with technical aspects of the broad interests of the Federation.
These publications are intended to provide background information through a review of technical practices and detailed procedures that research and experience have shown to be functional and practical. Jones, Chair J.

The initial chapter introduces the organization and administrative phases of the sanitary sewer project. Subsequent chapters are presented in a sequence detailing the parameters necessary to establish the design criteria, complete the design, and award a construction contract. The Manual concludes with a discussion of the commonly used trenchless and conventional methods of sanitary sewer construction.
This Manual is intended to be of practical use to the designer of a gravity sanitary sewer system and is based upon the experience of engineers in the field of sanitary sewer structural and hydraulic design. Charts, illustrations, and example problem solutions are used liberally throughout to reinforce the text. Wallace, Inc. Definition of Terms and Classification of Sanitary Sewers.

In , a second joint committee was formed to revise and expand the Manual; in , the revised edition was published. In subsequent reprintings, the edition of the Manual was continuously revised to provide information on improved and more current practices. This Manual should be considered by the practicing engineer as an aid and a checklist of items to be considered in a gravity sanitary sewer project, as represented by acceptable current procedures.
It is not intended to be a substitute for engineering experience and judgment, or a treatise replacing standard texts and reference material. In common with other manuals prepared on special phases of engineering, this Manual recognizes that this field of engineering is constantly progressing with new ideas, materials, and methods coming into use.
Other alternatives available to the designer of sanitary sewers include vacuum, pressure, vacuum-pressure, and small-diameter gravity sewers. The members of the Committee thank the reviewers of this Manual for their assistance in submitting their suggestions for improvement.
Sanitary systems are essential to protecting the public health and welfare in all areas of concentrated population and development. Every community produces wastewater of domestic, commercial, and industrial origin.
Sanitary sewers perform the vitally needed functions of collecting these wastewaters and conveying them to points of treatment and disposal. The various stages of design and construction of sanitary sewer projects require an understanding of the objectives of each stage of the project and of the responsibilities and interests of the parties involved. Separate sanitary and storm sewers are highly desirable and are used, with few exceptions, in new systems. The major advantages of separate systems, including wastewater treatment plants, are the protection of watercourses from pollution and the exclusion of stormwater from the treatment system with a consequent saving in treatment plant construction and operating cost.
Combined sewers are frequently encountered in older communities where it may be extremely difficult or costly to provide separate systems. Separation is desired, where economically feasible, to reduce the magnitude of facilities and energy demand of treatment works. Municipal sewer systems have been a major topic of regulatory interest since the late s with the introduction of the Sanitary Sewer Overflow Rule and changes in financial accounting and reporting standards for state and local governments.
A National Pollutant Discharge Elimination System NPDES permit must be issued to include the allowable discharge points for treated wastewater, combined sewer overflows, and emergency relief overflows. However, Section a of the CWA does not include sufficient information to indicate if and when a sanitary sewer overflow SSO might be permitted. Of important relevance, the new standard requires that municipalities record and report depreciation on their wastewater infrastructure assets.
Municipalities are required to use an asset management system that maintains a current inventory of their wastewater and associated sewer system infrastructure. Building Sewer: In plumbing, the extension from the building drain to the public sewer or other place of disposal. Also called House Connection. Combined Sewer: A sewer intended to receive both wastewater and storm or surface water.
Force Main: Liquid conveyance under pressure to raise liquid to the desired elevation. Lateral Sewer: A sewer that discharges into a branch or other sewer and has no other common sewer tributary to it. Main Sewer: 1 In larger systems, the principal sewer to which branch sewers and submains are tributary; also called Trunk Sewer.
In small systems, a sewer to which one or more branch sewers are tributary. Relief Sewer: 1 A sewer built to carry flows in excess of the capacity of an existing sewer. Relief sewers may also be used to eliminate overflows to combined sewer outfalls when they are constructed as part of a treatment plant and expansion. Sanitary Sewer: A sewer that carries liquid and waterborne wastes from residences, commercial buildings, industrial plants, and institutions, together with minor quantities of ground, storm, and surface waters that are not admitted intentionally.
See also Wastewater. Separate Sewer: A sewer intended to receive only wastewater, stormwater, or surface water. Separate Sewer System: A sewer system carrying sanitary wastewater and other waterborne wastes from residences, commercial buildings, industrial plants, and institutions, together with minor quantities of ground, storm, and surface waters that are not intentionally admitted.
See also Wastewater, Combined Sewer. Storm Sewer: A sewer that carries stormwater and surface water, street wash and other wash waters, or drainage, but excludes domestic wastewater and industrial wastes. Also called Storm Drain. Outfall: 1 The point, location, or structure where wastewater or drainage discharges from a sewer, drain, or other conduit. Outfall Sewer: A sewer that receives wastewater from a collecting system or from a treatment plant and carries it to a point of final discharge.
Trunk Sewer: A sewer that receives many tributary branches and serves a large territory.

A sanitary sewer or foul sewer is an underground pipe or tunnel system for transporting sewage from houses and commercial buildings but not stormwater to treatment facilities or disposal. Sanitary sewers are part of an overall system called a sewage system or sewerage. Sewage may be treated to control water pollution before discharge to surface waters. Separate sanitary sewer systems are designed to transport sewage alone. In municipalities served by sanitary sewers, separate storm drains may convey surface runoff directly to surface waters.
