The Impact of Rainfall on Landfill Leachate Treatment

The Relationship Between Rainfall and Leachate Treatment

Rainfall is a significant factor that influences the volume of leachate that a landfill can treat each year. In the case of a landfill with a surface area of 6000 m2 and an annual rainfall of 300 mm, it is crucial to understand how this precipitation impacts the leachate collection system's efficiency. With 20% of the rainfall resulting in runoff and 80% infiltrating the surface, the leachate collection system plays a vital role in treating the water that penetrates the landfill.

Volume of Leachate Treated Annually

Given that 80% of the 300 mm rainfall infiltrates the surface, the volume of leachate treated by the collection system is 90% effective, which amounts to 3240 m3 per year. This means that the landfill can successfully manage and treat 3240 m3 of leachate annually, ensuring that any potential environmental impacts are minimized.

Importance of Adequate Treatment

Effective leachate treatment is essential in reducing the environmental impact of landfills. By managing the volume of leachate generated from rainfall and ensuring it is properly treated, the landfill can operate in a more sustainable and environmentally friendly manner. This process helps prevent contamination of surrounding soil and water sources, ultimately contributing to a healthier ecosystem.
