Mainly because of water leaching from the effluent drains of a lot of closely spaced septic systems, [39] many council districts (e.g. Sunshine Coast, Queensland) have banned septic systems, and require them to be replaced with much more expensive small-scale sewage treatment systems that actively pump air into the tank, producing an aerobic ...
OSSFs account for approximately 25% of all domestic wastewater treatment in the US. Onsite sewage facilities may also be based on small-scale aerobic and biofilter units, membrane bioreactors or sequencing batch reactors. These can be thought of as scaled down versions of municipal sewage treatment plants, and are also known as "package plants ...

Septic systems are commonly used to treat wastewater from homes and small businesses in rural and suburban areas. [9] It consists of the tank and a septic drain field. Waste water enters the tank where solids can settle and scum floats.
The small treatment plants could each handle up to 75,000 gallons of sewage a day, which Licking County authorities say could accommodate subdivisions of up to 60 houses or a hotel-restaurant complex.
