Sewage discharge refers to the release of wastewater, which contains human waste, chemicals, and other pollutants, into the environment. This process often occurs through sewage treatment plants, where wastewater is treated to remove harmful substances before being released into rivers, lakes, or oceans. However, in some cases, untreated sewage may be discharged directly, especially during heavy rainfall or system failures. The impact of sewage discharge can be significant, leading to water pollution and harming aquatic life. It can also pose health risks to humans, as contaminated water can spread diseases. Proper management and treatment of sewage are essential to protect both the environment and public health.
