What is a freestanding sewage system?
The freestanding or aboveground sewage-ejector system is another waste removal option that does not require cutting through concrete .

The Up Jon system from Zoeller sells for around $600, but does not include a toilet. Saniflo also sells similar graywater and sewage-ejection systems designed specifically for bathtubs, showers, laundry units, and kitchen sinks.
