The grinder pump “station” consists of the pump, a tank, and an alarm panel. A pump for household use is usually 1 hp , 1.5 hp or 2 hp . A cutting mechanism macerates waste and grinds items that are not normally found in sewage, but may get flushed down the toilet.
KOS+ M openwell submersible pump. Small-scale sewage pumping is normally done by a submersible pump. This became popular in the early 1960s, when a guide rail system was developed to lift the submersible pump out of the pump station for repair, and ended the dirty and sometimes dangerous task of sending people into the sewage or wet pit.

The storage volume of the wet well between the "pump on" and "pump off" settings is designed to minimize pump starts and stops, but is not so long a retention time as to allow the sewage in the wet well to go septic. Sewage pumps are almost always end-suction centrifugal pumps with open impellers and are specially designed with a large open ...
Backflow prevention device. The simplest, most reliable way to provide backflow prevention is to provide an air gap.An air gap is simply an open vertical space between any device that connects to a plumbing system (like a valve or faucet) and any place where contaminated water can collect or pool.
You can -- and should -- hook up your home to city sewage or a septic tank. Not surprisingly, options get a bit trickier those looking for mobile, off-the-grid living. Because nothing takes the ...
Where it is impossible or impractical to discharge sewage from a property into a gravity sanitary sewer, a pressure sewer may provide an alternative means of connection. A macerator pump in a pumping well close to the property ejects sewage through a small diameter high pressure pipe into the nearest gravity sewer. [9]
Effluent sewer systems are a much less common sewage disposal method than gravity sewer systems that use gravity, as well as pumping where needed, to send raw sewage and other wastewater straight from consumers to a sewage treatment plant. There are two main types of gravity sewers, sanitary and combined. Sanitary sewers only treat the ...
That test will go forward as planned, McGovern said. Duke typically tests sirens around Shearon Harris between 10 a.m. and 11 a.m., with the alarms sounding between five and 30 seconds.
