These systems incorporate septic tanks connected to drain fields, on-internet site sewage systems (OSS), vermifilter systems and several additional. On the flip side, advanced and comparatively high-priced sewage treatment plants could involve tertiary treatment with disinfection and possibly even a fourth treatment phase to remove micropollutants.[7]
