In a sewer system, wastewater is transported to a centralized treatment plant. In a septic system, the treatment happens on-site, at the property.
The drainfield is an underground system of trenches or pipes that disperse the treated effluent from the septic tank into the surrounding soil for further filtration and purification.
Slow draining toilets, gurgling pipes, sewage backups, and unpleasant odours are all potential indicators of a failing system.
Overuse, improper maintenance, (infrequent pumping), and improper disposal of household chemicals can all lead to problems.
A strong odour could indicate a problem. It’s best to have the system inspected by a professional.

RotoTank combo systems are designed for simple plug-and-play setup. The pump connects to the tank using a suction hose kit, while a float valve kit controls the water level.
