Wastewater Treatment Overview

Wastewater Treatment Overview

Modern sanitary sewer collections systems move wastewater through a series of pipes from residential buildings, businesses and industrial sites to wastewater treatment facilities for processing and discharge. Some older systems know as combined sewer systems also carry stormwater runoff in addition to the wastewater from residential and commercial sources.

The wastewater flows through underground sewer mains, most often by gravity but sometimes assisted by pumps situated at lift stations. Depending on the topography of an area, these force mains vary in length up to a few miles long. Interceptors are locations where two lines meet and flow into a larger pipe and can include large chambers accessible by manholes.

Flow Monitoring
  • Does your collection system experience excess flow during dry and wet weather?  Have you confidently located the source?

  • Do you ever experience sewer overflows?

  • Are you confident your collection system can handle additional flows from residential and commercial expansion?

  • Do you need to spot check or verify flow rates using a handheld instrument?
