The unhealthy disposal of solid waste is considered one of the most alarming problems. Improper disposal of solid wastes contribute to air, soil and water pollution. Thus, this study aimed to assess the levels of knowledge, awareness and compliance on the existing waste management programs being implemented specifically on the different categories of construction sites in Davao City. Further, this investigation also attempted to establish whether there exist significant relationships among these variables. The researchers used descriptive survey with reliability coefficients 0.73 for knowledge, 0.92 for awareness and 0.90 for compliance and they were administered to 102 respondents consisting of project engineers, foremen and construction workers. Findings revealed an average level of knowledge, high level of awareness and high level of compliance among the respondents. The study also established a high positive correlation between awareness and compliance but failed to establish the link between knowledge and compliance. Therefore, the awareness of the workers in the construction sites reinforces the compliance with the rules and regulations required under the R.A. 9003 and the liquid waste management disposal provision promulgated by the government sectors, the company and the law.
