The majority of local plumbing ordinances required the use of wrought or cast iron and limited the use of lead pipes to connectors (goose-necks or pig-tails) or placed other restrictions on lead pipes. As noted above, the San Jose plumbing ordinance does not list lead as an approved pipe material which is similar to the Los Angeles ordinance ...
A sanitary sewer is an underground pipe or tunnel system for transporting sewage from houses and commercial buildings (but not stormwater) to a sewage treatment plant or disposal. Sanitary sewers are a type of gravity sewer and are part of an overall system called a "sewage system" or sewerage .
This code is also used as the basis for the plumbing codes of some other countries. Another model plumbing code published and utilized widely across the United States is the Uniform Plumbing Code , published by the International Association of Plumbing and Mechanical Officials ( IAPMO ), a multinational operation with offices in 13 nations.
Vitrified clay pipe (VCP) is pipe made from a blend of clay and shale that has been subjected to high temperature to achieve vitrification, which results in a hard, inert ceramic. VCP is commonly used in gravity sewer collection mains because of its long life and resistance to almost all domestic and industrial sewage , particularly the ...
The IPC is the most widely used plumbing code in the United States and is also used as the basis for the plumbing code of several other countries [citation needed].Wide adoptions are important as they help reduce manufacturer and end-user costs by allowing the use of materials across a wide user base, thus allowing economies of scale in the production of materials used in construction.
A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.

In many countries, PVC pipes account for most pipe materials used in buried municipal applications for drinking water distribution and wastewater mains. [10] Pipe may be made from concrete or ceramic, usually for low-pressure applications such as gravity flow or drainage. Pipes for sewage are still predominantly made from concrete or vitrified ...
