Total Water Needs Calculation

Oct 13, 2025 by windailys.com 35 views

Introduction

Water is a vital element in human life, and its quality is crucial for safe and healthy consumption. In Indonesia, the Minister of Health Regulation No. 492/MENKES/PER/IV/2010 stipulates the physical, chemical, and biological standards for water quality. Unfortunately, groundwater in Pantai Labu District, Deli Serdang Regency, has been contaminated by waste from septic tanks and industrial and household waste, making it unfit for consumption. This condition has led to a high demand for clean water, with many residents opting to buy it as an alternative.

Background

The Pantai Labu District, located in Deli Serdang Regency, has a significant population that relies on groundwater for their daily needs. However, the water quality in the area has been compromised due to the presence of contaminants from septic tanks and industrial and household waste. The high levels of dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), and iron (Fe) in the water make it unfit for consumption. This situation has raised concerns about the health and well-being of the community, particularly children, pregnant women, and the elderly.

Research Objectives

The primary objective of this research is to design clean water treatment installation buildings that can meet the needs of the community in Pantai Labu District. The research aims to:

Analyze the current water quality in the area and identify the contaminants present
Determine the total water needs of the community
Design a clean water treatment installation that can meet the water needs of the community
Identify the processing units required for the treatment installation

Methodology

The research methodology involved the following steps:

Water Quality Analysis: The water quality in the area was analyzed using various parameters, including DO, BOD, COD, and Fe.
Total Water Needs Calculation: The total water needs of the community were calculated based on the population size and water usage patterns.
Design of Clean Water Treatment Installation: A clean water treatment installation was designed to meet the water needs of the community. The installation consisted of the following processing units:
- Unit Intake: a place to take water from the source
- Coagulation Unit: the process of combining small particles to form larger particles that can settle
- Flocculation Unit: stirring water that has undergone coagulation to speed up the depositional process
- Filtration Unit: separates fine particles from water
- Disinfection Unit: eliminates pathogenic microorganisms to make the water safe for consumption
- Reservoir Unit: stores clean water that has been processed before it is distributed to the community
Infrastructure Planning: The infrastructure required for the clean water treatment installation was planned, including the construction of buildings, roads, and other necessary facilities.

Results

The results of the research showed that the current water quality in the area did not meet the requirements as clean water based on government regulations No. 82 of 2001. The total water needs of the community were found to be 1,016,460 liters per day, or equivalent to 22 liters of discharge per second. The design of the clean water treatment installation was found to be feasible and can meet the water needs of the community.

Conclusion

The research concluded that the design of clean water treatment installation buildings is essential to meet the needs of the community in Pantai Labu District. The installation should consist of the following processing units: Unit Intake, Coagulation Unit, Flocculation Unit, Filtration Unit, Disinfection Unit, and Reservoir Unit. The infrastructure required for the installation should be planned carefully to ensure that it meets the needs of the community.

Recommendations

Based on the research findings, the following recommendations are made:

The government should invest in the construction of clean water treatment installations in Pantai Labu District to meet the water needs of the community.
The community should be educated on the importance of clean water and the need to maintain the water treatment installations.
The infrastructure required for the clean water treatment installations should be planned carefully to ensure that it meets the needs of the community.

Future Research Directions

Future research directions should focus on the following areas:

Conducting a detailed analysis of the water quality in the area to identify the contaminants present and their sources.
Developing a more detailed design of the clean water treatment installation, including the selection of materials and equipment.
Conducting a cost-benefit analysis of the clean water treatment installation to determine its feasibility and sustainability.

Limitations of the Study

The study has the following limitations:

The study was conducted in a specific area, and the results may not be generalizable to other areas.
The study did not consider the social and economic factors that may affect the implementation of the clean water treatment installation.
The study did not conduct a detailed analysis of the water quality in the area, which may have affected the accuracy of the results.

Conclusion

In conclusion, the research found that the design of clean water treatment installation buildings is essential to meet the needs of the community in Pantai Labu District. The installation should consist of the following processing units: Unit Intake, Coagulation Unit, Flocculation Unit, Filtration Unit, Disinfection Unit, and Reservoir Unit. The infrastructure required for the installation should be planned carefully to ensure that it meets the needs of the community. The government should invest in the construction of clean water treatment installations in Pantai Labu District to meet the water needs of the community.
