Sewage canals are specially designed channels that transport wastewater and sewage away from urban areas. They help manage and dispose of human waste, preventing contamination of the environment and protecting public health. These canals are often part of a larger sewage system that includes treatment plants to process the waste before it is released back into the environment. Typically constructed from concrete or other durable materials, sewage canals are engineered to handle large volumes of liquid. They are essential in cities where high population density generates significant amounts of waste. Proper maintenance of these canals is crucial to ensure they function effectively and do not overflow, which can lead to flooding and health hazards.
