The cost of sewerage - conventional or simplified - are always site-specific, and estimates are subject to controversies. Construction costs of simplified sewerage are up to half the costs of conventional sewerage. Investment cost savings come from various design features that may or may not be present in a particular simplified sewerage system.
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 .
The capitalized cost of operation and maintenance of lift stations and emergency power supplies usually justifies considerable first cost for excavation or tunneling to build a gravity sewer. [3] Sewage treatment is most efficient at centralized locations; and pumping is often required to lift sewage from lower elevations to the sewage ...

Sewers under construction in Ystad, Sweden. Types of sanitary sewer systems that all usually are gravity sewers include:
A vacuum sewer or pneumatic sewer system is a method of transporting sewage from its source to a sewage treatment plant. It maintains a partial vacuum , with an air pressure below atmospheric pressure inside the pipe network and vacuum station collection vessel.
Schember told City Council members on Wednesday morning that the proposed sewer rate increase would boost the average city residential customer's sewer rates from roughly $340 a year to $348, or ...
This installation method is by far the most labor-intensive. In addition, material cost is a function of the width of the grate used in the trench. There are three main reasons why this is labor-intensive: the outlet pipe position in the floor, the levelling of the trench grate in the floor, and integration of the waterproofing.
