What is a sewage ejector tank?

Sewage Ejector tank and pump system: A system used to lift the discharge from the fixtures located below the crown level of the sewer to the building drain or building sewer. Sewage ejector tank and pump sewage straight to the main sewage line. Sewage is wastewater and human waste arising from domestic premises and may contain waste arising from toilets and similar fixtures, showers, baths, hand basins, clothes washing machines, laundry tubs, kitchen sinks, and dishwashers. Sewage includes black water and greywater but not stormwater.

A typical application of a sewage ejector pump is in a home where a basement bathroom is located lower than the height of the sewer line. The sewage ejector pump lifts waste from the basement bathroom up to the sewer line where it flows out to a septic tank or community sewer. The volume of the sewage ejector tank must be large enough to accommodate any drain back from the piping and to effectively dose the system. Whenever such a pump is used to deliver toilet waste to a septic tank, the volume must be limited to minimize the impact on the tank.

The sewage ejector tank and the pump are designed to temporarily store sewage prior to comminution/maceration and/or discharge directly to a sewer. The unit then shall have that sewage entering the pit shall be carried to the strainer baskets installed in pump discharge lines. These sewage ejector tanks are made of corrosion-resistant materials, and are typically buried flush with the floor of the lowest living space. When filled to a certain level the ejector pump transports sewage out of the home. Solids will be retained in the baskets and liquids will continue through the casing into the basin. The strainer shall have cast iron housing and a stainless steel basket, removable from the top of the housing. Solids shall be flushed into the discharge line during the discharge cycle. A control valve shall prevent back-up into the house line during discharge cycles and permit cut-off of either pump. Overflow fitting shall allow the liquid to flow
