Growth of the submersible pump for sewage pumping since has been dramatic, as an increasing number of specifiers and developers learned of their advantages. Three classes of submersible pumps exist: Smaller submersible pumps, used in domestic and light commercial applications, normally handle up to 55 millimetres (2.2 in) spherical solids and ...
A four pole or six pole AC induction motor normally drives the pump. Rather than provide large open passages, some pumps, typically smaller sewage pumps, also macerate any solids within the sewage breaking them down into smaller parts which can more easily pass through the impeller. The interior of a sewage pump station is a very dangerous place.
Section 312 has another means of addressing sewage discharges, through establishment of no-discharge zones (NDZs) for vessel sewage. A state may completely prohibit the discharge of both treated and untreated sewage from all vessels with installed toilets into some or all waters over which it has jurisdiction (up to 3 miles (4.8 km) from land).

("Marpol" is short for marine pollution and 73/78 short for the years 1973 and 1978.) [11] Marpol 73/78 is one of the most important international marine environmental conventions. It was designed to minimize pollution of the seas, including dumping, oil and exhaust pollution.
Maceration, in sewage treatment, is the use of a machine that reduces solids to small pieces in order to deal with rags and other solid waste.Macerating toilets use a grinding or blending mechanism to reduce human waste to a slurry, which can then be moved by pumping.
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges.

A transfer station, or resource recovery centre, is a building or processing site for the temporary deposition, consolidation and aggregation of waste. [ 1 ] [ 2 ] Transfer stations vary significantly in size and function.
