Pressure sewers enable properties constructed below the nearest gravity main to connect to the local sewerage system avoiding the need for a septic tank or cesspit. [ 4 ] In areas where washouts or earthquakes are common, conventional earthenware or cast iron sewerage system may be prone to breakage and leakage.
A force main or rising main [8] is a pumped sewer that may be necessary where gravity sewers serve areas at lower elevations than the sewage treatment plant, or distant areas at similar elevations. A lift station is a sewer sump that lifts accumulated sewage to a higher elevation.
Initially no funding was provided for inspections. [4] 2,500 dollars was eventually provided in 1882 [5] Inspections had begun in 1882 and by the end of the year 9,871 inspections had been completed [6] The law required that only iron pipe be used. [7] The law required that ferules be made of brass or lead and not iron.
A sanitary manhole (sewer manhole, [1] sanitary sewer manhole [2] or sewer maintenance hole [3]) is a manhole that is used as an access point for maintenance and inspection of an underground sanitary sewer system. Sanitary manholes are sometimes used as vents to prevent the buildup of pressurized sewage gas. [4]
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.
Map of Seattle sewer districts, 1894. The main part of such a system is made up of large pipes (i.e. the sewers, or "sanitary sewers") that convey the sewage from the point of production to the point of treatment or discharge. Sewers under construction in Ystad, Sweden. Types of sanitary sewer systems that all usually are gravity sewers include:

The pipes from the home are connected to the inlet; the pipe that leads to the sewer main is connected to the discharge. Often, more than one home or restroom (in a park, for example) can be connected to one grinder pump station. In this case, more than one inlet can be installed.
