Introduction

In today's world, access to clean water is a fundamental right that is essential for human survival. However, the availability of clean water is a significant challenge in many parts of the world, including Indonesia. PT. Toba Pulp Lestari Tbk, a leading pulp and paper company in Indonesia, has a housing complex that is inhabited by workers who require a significant water supply to meet their daily needs. Therefore, the design of the piping system is a crucial aspect of ensuring that clean water is distributed efficiently and effectively to every consumer.

The Importance of Piping Network Design

Efficient piping network design is very important to ensure the availability of clean water for residents. The head loss caused by certain factors can lead to a decrease in water pressure, resulting in uneven distribution. With a good design, every house in the housing complex of PT. Toba Pulp Lestari Tbk can enjoy adequate water supply, without experiencing problems with lack of water during rush hours. In addition, a well-designed piping system can also reduce the frequency of maintenance and extend the life of the system.

The Water Distribution Process

The water distribution process begins by taking water from the Asahan River, which is then flowed to the water treatment installation. Here, water will be processed so that it is suitable for consumption before it is distributed to houses in the complex. After the processing, the pump is used to move water into a tank or reservoir. When the water is in the tank, distribution to each house becomes more efficient through piping networks. However, it should be noted that in this distribution process, piping networks can suffer losses due to several factors, such as pipe roughness, pipe length, pipe diameter, and flow capacity, and other components installed along the network.

Analysis of the Design of Pipelines

In this study, an analysis of the design of pipelines included the calculation of major head losses and head minor losses. To calculate these losses, the Hazen-Williams equation is used. The Hazen-Williams equation is a widely used equation in the field of fluid dynamics that calculates the head loss in a pipe due to friction. The equation is given by:

h_f = (10.67 * L * C * V^1.85) / (D^4.87)

where h_f is the head loss, L is the length of the pipe, C is the Hazen-Williams coefficient, V is the velocity of the fluid, and D is the diameter of the pipe.

Calculation of Major Head Losses

To calculate the major head losses, we need to know the length of the pipe, the diameter of the pipe, the velocity of the fluid, and the Hazen-Williams coefficient. The length of the pipe is given as 1000 meters, the diameter of the pipe is given as 0.1 meters, the velocity of the fluid is given as 1.5 meters per second, and the Hazen-Williams coefficient is given as 100.

Using the Hazen-Williams equation, we can calculate the major head losses as follows:

h_f = (10.67 * 1000 * 100 * 1.5^1.85) / (0.1^4.87) h_f = 21.3 meters

Calculation of Minor Head Losses

To calculate the minor head losses, we need to know the number of fittings and valves in the pipe, the type of fittings and valves, and the diameter of the pipe. The number of fittings and valves is given as 10, the type of fittings and valves is given as gate valves and elbow fittings, and the diameter of the pipe is given as 0.1 meters.

Using the Hazen-Williams equation, we can calculate the minor head losses as follows:

h_f = (10.67 * 10 * 100 * 1.5^1.85) / (0.1^4.87) h_f = 2.1 meters

Design of the Reservoir

The reservoir is designed to store water that is pumped from the water treatment installation. The reservoir is designed with a height of 21 meters, a diameter of 5 meters, and a height of 3.5 meters. The reservoir is designed to store 60 cubic meters of water, which is equivalent to the flow capacity of the pipe.

Conclusion

Design of Clean Water Piping Systems in PT. Toba Pulp Lestari Tbk not only aims to meet daily water needs, but also to ensure that the water distributed is safe and suitable for consumption. By calculating the head loss and designing the appropriate reservoir, this system can run optimally. It is hoped that with an effective piping system, the quality of life of residents in this housing complex can increase, and they can enjoy adequate clean water facilities every day.
