The wastewater system relies on the force of gravity to move sewage from your home to the treatment plant.So wastewater-treatment plants are located on low ground,often near a river into which treated water can be released.If the plant is built above the ground level,the wastewater has to be pumped up to the aeration tanks (item 3).From here on,gravity takes over to move the wastewater through the treatment process.
