This study explores household waste disposal practices in Dimapur, Nagaland, and investigates the role of infrastructure and behavioral awareness in shaping disposal behavior. A cross-sectional survey of 460 households was conducted to assess disposal methods and reasons for informal disposal. Chi-square and Spearman rank correlation tests were applied to examine associations between drainage infrastructure, segregation awareness, and disposal behavior. Results show that 60% of households rely on municipal garbage trucks, while 40% continue informal practices such as burning, dumping, and open disposal. Lack of provision for waste disposal facilities was the most cited reason for such behavior. The statistical analysis revealed no significant association between drainage type and disposal method (p = 0.431) and no significant correlation between awareness and responsible behavior (p = 0.579). The findings highlight the need for integrated strategies combining service delivery with public engagement.
