Abstract
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.
