Introduction

The availability of clean water is a vital resource for human life, and its existence plays a crucial role in maintaining public health and encouraging economic growth. In Langkat Regency, North Sumatra, PDAM Tirta Wampu is responsible for providing clean water for the community. To ensure optimal water supply, an accurate estimate is needed about the amount of drinking water to be distributed in the future. This study aims to forecast the amount of drinking water channeled by PDAM Tirta Wampu Langkat Regency in 2008-2010 using a double exponential smoothing method.

The Importance of Forecasting Drinking Water Needs

Forecasting the amount of drinking water is essential for ensuring adequate water supply and avoiding water waste. By predicting the amount of drinking water to be distributed, PDAM Tirta Wampu can:

Increase efficiency: Ensure adequate water supply and avoid water waste.
Manage resources: Utilize water resources optimally and avoid lack of water.
Plan development: Prepare adequate infrastructure to meet the needs of clean water in the future.
Minimize the water crisis: Project water needs and take anticipatory steps to prevent water crises.

Data Analysis and Forecasting Model

This study will analyze the data consumption of drinking water PDAM Tirta Wampu Langkat Regency in 2008-2010. The data will be processed using the double exponential graduate method to get an accurate forecasting model. This model will consider factors such as:

Population growth trend: Increased population will have an impact on increasing water demand.
Economic growth: Along with economic growth, clean water needs will increase.
Season: Demand for water tends to be higher in the dry season compared to the rainy season.
Other factors: Other factors such as natural disasters or climate change can also affect water consumption.
