Study of Semi-Urban Wastewater Characteristics Used for Agriculture

In semi-arid and arid regions, wastewater serves as a baseline for agricultural practices. The use of semi-urban wastewater in agricultural fields provides nutrients to crops due to the presence of organic wastes, excreta, and sludge. Historically, wastewater and sewage sludge, much like manure, have been utilized by northern European and Mediterranean civilizations for agricultural enhancement. However, in Mysuru, the application of both treated and untreated wastewater remains under-explored. This study analyzes both primary and secondary parameters to assess the actual condition of urban wastewater (UWW) in Mysuru city. Our findings indicate that the investigated UWW is generally suitable for agricultural purposes, with the exception of the Kesare UWW treatment plant, which lacks sufficient nutrients. These insights could guide sustainable agricultural practices and wastewater management in similar semi-urban environments.
