STEP systems includes a holding tank for sewage, a screen chamber, and a small pressure pump within the tank. The liquid waste is pumped through a small pressure line into sewer lines leading to the LOTT Wastewater Treatment Plant.
The STEP system pump is controlled by a system of floats within your tank. The electrical box mounted on the side of your house controls the floats and pumps. The floats activate an alarm in the electrical (alarm) box when the fluid level in the tank gets too high or too low.
Periodically (approximately every seven years), the City pumps out the holding tank sewage.
