Engineered Grinder Pumps and Applications are typically provided as a system. A grinder pump system consists of the pump in a tank coupled to a control panel that also includes an alarm to indicate pump failure. These that are typically designed for use in residential applications are usually 2 hp. Grinders used in multiple family or industrial applications are available up to 7 ½ hp. The grinding or cutting mechanism macerates waste and grinds items that are not normally found in sewage, but may get flushed down the toilet. The pump system has level sensors called float switches. If the pump malfunctions and the waste level in the holding tank rise above a certain level, the alarm panel should alert the owner that the pump is experiencing problems. The alarm panel uses an indicator light that flashes to gain attention.
Engineered Grinder pumps are usually installed in fiberglass tanks. The fiberglass tank, (FRP), has an inlet opening and a discharge opening. The pipes from the home(s) or factory 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. The tank has a lid made from heavy-duty plastic or metal that is bolted and/or padlocked shut to prevent entry by unauthorized persons.
Disposable wipes that are made by cleaning companies for personal use, cleaning toilets, etc. are causing problems in communities around the United States. Not only do people clog their household plumbing, they are causing problems with household grinder pumps, lift stations, and sewage treatment plants. Some wipe companies say “flush one at a time,” some say “not for pump systems,” some say “safe for sewers.” As recommended by Consumer Reports, wipes should be put into a garbage can instead of the toilet. The National Association of Clean Water Agencies has compiled a list of articles and municipal documents regarding wipes.
