Wastewater then enters the second section or sedimentation tanks. Grit is pumped out of the tanks and taken to landfills. Bubbling oxygen through the water also keeps the organic material suspended while it forces 'grit' (coffee grounds, sand and other small, dense particles) to settle out. In the first section, air is pumped through the water.Īs organic matter decays, it uses up oxygen. Wastewater enters a series of long, parallel concrete tanks. This causes some of the dissolved gases (such as hydrogen sulfide, which smells like rotten eggs) that taste and smell bad to be released from the water. One of the first steps that a water treatment facility can do is to just shake up the sewage and expose it to air. From here on, gravity takes over to move the wastewater through the treatment process. If the plant is built above the ground level, the wastewater has to be pumped up to the aeration tanks (item 3). So wastewater-treatment plants are located on low ground, often near a river into which treated water can be released. The wastewater system relies on the force of gravity to move sewage from your home to the treatment plant. Most of these materials are sent to a landfill. Unless they are removed, they could cause problems later in the treatment process. Wastewater entering the treatment plant includes items like wood, rocks, and even dead animals.
