A DEWATS (Decentralized Wastewater Treatment System) is an inexpensive and effective wastewater treatment technology, particularly in developing nations. It has significant potential for creating a long-term environmental sanitation system. The treatment of water and wastewater, as well as its reuse for household, industrial, or agricultural purposes, serves to conserve and improve water quantity and quality. Green technologies currently supply high-quality water without incorporating global warming. Several conventional treatment methods successfully eliminate various pollutants and contaminants from wastewater. Still, they require many external sources, labor, and pumping systems, as well as higher maintenance and operation costs. Due to several issues with traditional treatment procedures, soil biotechnology (SBT) was implemented to establish a pollution-free environment. Soil biotechnology (SBT) is a water regeneration technique that uses specific media containing soil micro- and macroorganism culture to process water and wastewater.
