Sometimes you take for granted that everyone working in the industry knows why our systems are so important to the environment and human health. During the last few months, we have had some questions about what is in wastewater and why it is a problem. This is where we start our basic sewage treatment workshops. We thought it would be helpful to go back to the beginning and discuss pollutants and potential problems. We will follow up these discussions over coming months looking at some specific ways to address the concerns.
Professionally designed, sited and installed conventional onsite sewage treatment systems effectively reduce or eliminate most human health and environmental hazards. This is accomplished through physical, chemical and biological processes in the septic tank, in the biomat and in the unsaturated soil zone beneath operating soil treatment trenches.
