Lagoon Wastewater Treatment System
Lagoon wastewater treatment systems use a series of large ponds to naturally clean wastewater over time. These systems are simple, reliable and effective, using natural biological processes to remove contaminants from the water.
When wastewater arrives at the treatment plant, it may first pass through a screen that removes larger items such as wipes, sanitary products and other materials that should not be flushed. These materials, often called "rags", are collected and disposed of separately.
The wastewater then flows slowly through a series of lagoons. As it moves through each pond, naturally occurring bacteria and other microorganisms break down organic matter and help remove contaminants. Solids settle to the bottom, while sunlight, oxygen and natural biological processes continue to improve water quality.
Once treated, the water can be recycled for beneficial uses such as irrigating crops and pasture, or managed through evaporation and drying basins. Throughout the treatment process, some water is naturally lost through evaporation.
In this virtual tour, you'll follow the journey of wastewater through a lagoon treatment system and discover how natural processes work together to protect public health and the environment. Let's start at the inlet and explore how a lagoon wastewater treatment system works.
