How does Columbia wastewater work?
Sanitary sewers carry wastewater from homes and businesses to the raw wastewater pumping station at the Columbia Wastewater Treatment Plant (WWTP). The wastewater flows mostly by gravity to the WWTP. There are more than 25 pump stations that also direct wastewater to the collection system that flows to the WWTP. Routine cleaning and closed-circuit television inspection of Columbia’s sewer lines help keep the collection system in good shape. Each year, new construction in the City adds about 9 miles of sewer lines and 170 sewer structures to the sewer collection system.

What is the final setting basin?
Final Settling Basinsallow the clumps of biological mass (the microorganisms) to settle from the water by gravity. 90%-95% of this mixture, called “activated sludge,” is returned to the aeration basins to help maintain the needed amount of microorganisms. The remaining 5%-10% is pumped to the anaerobic digester for Biosolids Treatment.
What is the process of settling wastewater?
Primary Settling Basins allow smaller particles to settle from the wastewater by gravity . The primary wastewater flows out to the next stage of treatment called secondary treatment. Scrapers collect the solid matter, called “primary sludge,” from the bottom and pumps it to the anaerobic digester for further treatment. A surface skimmer collects scum or grease floating on top of the basins and sends it to the anaerobic digester.
