Analysis of Clean Water Distribution in PT. Chevron Pacific Indonesia Dumai District Employee Housing Complex from WTP-Dumai using Epanet 2.0 software (Case Study: Dumai City, Riau)

Introduction

Access to clean water is a fundamental human right, and ensuring its availability and quality is a critical aspect of public health and well-being. In the context of industrial and commercial settings, such as employee housing complexes, the provision of clean water is not only a necessity but also a reflection of the organization's commitment to the health and safety of its employees. This study aims to analyze the clean water distribution system in the employee housing complex of PT. Chevron Pacific Indonesia in Dumai, using Epanet 2.0 software, with a focus on identifying areas for optimization and improvement.

Background

PT. Chevron Pacific Indonesia, a leading energy company, has been operating in Dumai, Riau, since 1958. The company's water treatment plant (WTP-Dumai) has been providing clean water to its employees and their families, free of charge, without any measurement of water consumption. The clean water distribution pipelines in the housing complex are mostly old networks, with only a few parts replaced due to damage. This study aims to analyze the clean water distribution system in the employee housing complex of PT. Chevron Pacific Indonesia in Dumai, using Epanet 2.0 software, to identify areas for optimization and improvement.

Methodology

The research process involved the collection of primary and secondary data, calculating the number of population and water needs per service point, as well as modeling and analysis using Epanet 2.0 software. The results of the Epanet analysis 2.0 were then evaluated using the Hardy-Cross method on the piping network loop sample. The study also involved the collection of water quality data from the laboratory owned by PT. Chevron Pacific Indonesia.

Results

The results of the Epanet analysis 2.0 showed that the total water requirement for the entire housing complex is 184.56 liters/minute, with a peak of the need reaching 350,664 liters/minute at 06.00 based on the pattern of water use for 24 hours. The pipeline used is a PVC pipe with an 8-inch main pipe diameter and a 6-inch secondary pipe diameter. Water quality from the test results in the laboratory owned by PT. Chevron Pacific Indonesia showed a fairly good water quality with 1.86 chlorine content, 8.30 pH value, turbidity levels (turbidity) of 0.37 NTU, and water color value 1.00 PT Co.

Analysis and Discussion

The analysis using Epanet 2.0 software is proven to be able to represent calculations manually, as the evaluation results with the Hardy-Cross method on the loop in the Mendut complex are considered to represent the condition of the entire loop. The analysis showed a headloss that is quite large at 83,5649 meters. Evaluation of the diameter of the pipe with a diameter of 6 inches and 4 inches produces headloss of 56.86 meters and allows a decrease in pump heads from 85 meters to 60 meters.

Further Analysis

The Importance of Water Consumption Monitoring

Although clean water is given free of charge, it is essential for PT. Chevron Pacific Indonesia to consider the use of water meter. This can increase consumer awareness in saving water, reducing the potential for waste, and increasing the efficiency of water distribution.

Pipeline Optimization

Epanet Analysis 2.0 shows the potential for optimization in the pipeline, especially related to the pipe diameter. Pipe replacement with a more optimal diameter can reduce headloss and increase water distribution efficiency.

Water Quality

Even though the current water quality is good, it is necessary to monitor regularly to ensure that water quality is maintained and meets health standards.

Environmental Aspects Considerations

It is essential to consider environmental aspects of clean water management. The use of environmentally friendly technology and efficiency in water use can reduce the negative impact on the environment.

Conclusion

Modeling with Epanet 2.0 provides valuable information to understand the clean water distribution system in the employee housing complex of PT. Chevron Pacific Indonesia in Dumai. This analysis helps identify the potential optimization of pipelines and the need for monitoring water consumption to increase consumer efficiency and awareness in saving water.

Recommendations

Based on the findings of this study, the following recommendations are made:

Implementation of Water Metering System: PT. Chevron Pacific Indonesia should consider implementing a water metering system to monitor water consumption and increase consumer awareness in saving water.
Pipeline Optimization: The company should consider replacing old pipelines with more optimal diameters to reduce headloss and increase water distribution efficiency.
Regular Water Quality Monitoring: Regular monitoring of water quality is essential to ensure that water quality is maintained and meets health standards.
Environmental Considerations: The company should consider the environmental aspects of clean water management and use environmentally friendly technology and efficiency in water use to reduce the negative impact on the environment.

By implementing these recommendations, PT. Chevron Pacific Indonesia can improve the efficiency and effectiveness of its clean water distribution system, reduce waste, and promote a healthier and more sustainable environment for its employees and their families.
