A Study on Effect of Kitchen Wastewater Irrigation on Quality of Soil and Crop Growth

Roof Gardens, Backyard Gardens, Allotment Gardens, Community Gardens and Road side Gardens were part of green development in urban areas. The present irrigation facilities for these gardening are fulfilled by potable water from water treatment plants. The demand of water for irrigation of urban gardens is increasing day by day. Around 60 % of total water used in kitchen was converted in the form of wastewater. The biodegradable organic constituents present are around 80 % in kitchen wastewater. In the present practices highly concentrated kitchen wastewater is disposed off in municipal sewers or inland water bodies or on land directly. These practices are preliminarily responsible for pollution of ambient atmosphere. Also the plant nutrients present in kitchen wastewater are wasted. The objective of this study is to recycle the SBR treated centralized kitchen wastewater for Urban Irrigation. The research study includes a comparative study to determine quality of soil irrigated with Potable Water (PW), Treated Kitchen Waste Water (TKW) and Untreated Kitchen Wastewater (UKW). During this work growth of plants also observed with respect to quality of water used for irrigation.
