Abstract:
1. Introduction
Water is a vital resource for sustaining life on Earth, yet freshwater scarcity
has become one of the most critical global challenges. Industries also
heavily rely on water in every aspect. The aim of the study is conduct an in-
depth analysis of all water consumption processes, and the wastewater
treatment process of a plant, which is currently classified as having
medium to high water stress. Ensuring efficient water use is essential for
both enhancing sustainability and securing the long-term viability of the
plant.
2. Research Methodology
The research employs a quantitative approach to analyse the plant’s water
consumption over the past three years through numerical and graphical
data. The study utilizes a descriptive research design and a deductive
approach to effectively investigate water usage patterns. Data collection
methods include direct observations, informal interviews, and company
reports. Various analytical tools, such as Minitab, Excel, and the Rainwater
Harvesting Calculator Tool, along with guidelines from the Water Footprint
Manual and ISO 14046, are used to conduct the analysis.
3. Findings and Discussion
The results, presented through regression models and R-squared values,
reveal that 74.7% of variations in total water consumption can be
explained by variations of man-days, and 74% of variations of process
water can be explained by using production. The various potential monthly
water savings can be achieved in each month by targeting the lowest mean
consumption represented in October. Additionally, the greywater footprint
is calculated as 74.5m3/Day.
4. Conclusion and Implications
The findings offer valuable insights into optimizing water usage by giving
deep attention to the water behaviour of plants. If the company is able to
install a proper rainwater harvesting system, it will be able to collect
around 37000m3 /Year. The management can use water saving potentials
as a target for each month.
