In situations where a downward slope out of a building en route to a treatment system cannot be created, a special collection sump pit and grinding lift "sewage ejector" pump are needed. By contrast, potable water supply systems are pressurized up to 50 pounds per square inch (340 kPa) or more and so do not require a continuous downward slope ...
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.

Sewerage (or sewage system) is the infrastructure that conveys sewage or surface runoff (stormwater, meltwater, rainwater) using sewers. It encompasses components such as receiving drains , manholes , pumping stations , storm overflows, and screening chambers of the combined sewer or sanitary sewer .
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 ...
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 ...
A lot of the need for alarm management also arises because alarms can be configured on a DCS at nearly zero incremental cost, whereas in the past on physical control panel systems that consisted of individual pneumatic or electronic analogue instruments, each alarm required expenditure and control panel area, so more thought usually went into ...
Duke typically tests sirens around Shearon Harris between 10 a.m. and 11 a.m., with the alarms sounding between five and 30 seconds. Emergency alert that went out to many Wake County residents ...
