Eastern industrial park was constructed for social and economic development, though some of the industries inside the park are polluting the surrounding environment as they were not properly treated and discharged to the environment. Consequently, the paper intended to assess liquid waste management practices and the role of Communal treatment plant. In doing so, the researcher used mixed research employing both qualitative and quantitative data. Both primary and secondary data were used in the study. On the other hand, cluster, purposive and systematic sampling were used to select the required sample while SPSS software was used for quantitative data analysis and thematic analysis was employed for qualitative data analysis. Researcher found out that with the exception of Linda garment and Zhongshun Cement manufacturing the rest sampled companies had primary treatment plant. However, the treatment plant in each company was not efficient in treating the liquid wastes from the companies. On the other hand, based on perception of employees of industries there was no effective liquid waste communal treatment plant and the treatment of liquid waste in the communal treatment plant was not as per the national standard. Besides, there was no benefit of communal treatment plant for the environment in general and the health of local people in particular. Furthermore, there was no sufficient equipment and facilities, best selection of treatment process and good treatment system design in the communal treatment plant of Industrial Park. Formulation and enforcement of legislation and training and motivation of personnel were the factors that highly determine the existence of effective liquid waste management practices. While satisfaction with the financing and investment in equipment and facilities, training and motivation of personnel and agreement on the public education and involvement in the liquid waste management practices are the factors that highly determine the dependent variable the existence of sufficient facilities and equipment for liquid waste management practices. Each company was recommended to have efficient primary treatment plant. Besides, making sample test regularly from the effluents discharged to the communal treatment plant was also recommended by the researcher. Furthermore, the industry park recommended to plant efficient treatment plant with sufficient facilities using modern and efficient technologies that reduce liquid waste pollution.
