Abstract
Different industries discharge wastewater with different contaminants in the production
process. The heavy metals and other inert materials present in wastewater will
contaminate the environment by causing normal drainage systems and natural water
resources polluted. Therefore, it is a timely need to study detail on potential industries
that generate wastewater and their adoption measures at present to treat the wastewater.
With that objective twenty companies that represent eight different industries were
identified using secondary data and a structured questionnaire was used to collect data in
this study. Data were analysed by descriptive analysis method using Minitab 17 software.
The findings of this study emphasized that different industries have adopted different
wastewater management systems and analysis methods, however, their wastewater
treatment methods at present are of very expensive. Further cost for water consumption
by eight different industries is significantly different every month and recorded an
average of Rs. 4,700,000.00 per month. Among the eight different industries and the
highest cost recorded in the glove industry that costs about Rs. 5,000,000.00 per month.
Moreover, 98% of industries prefer to implement a cost-effective wastewater treatment
method in which each industry would be able to reuse the water and enhance the
efficiency of water usage in a sustainable way.
