The correct answer is: D. All the above.
A water carried sewerage system is a system that collects and removes wastewater from homes, businesses, and industries. It consists of a network of pipes that carry the wastewater to a treatment plant, where it is cleaned and then released back into the environment.
Domestic sewage is wastewater from homes and businesses. It includes human waste, food waste, and wastewater from sinks, showers, and toilets.
Industrial sewage is wastewater from factories and other industrial facilities. It can contain a variety of pollutants, including chemicals, heavy metals, and oils.
Storm sewage is wastewater that is generated during heavy rains or storms. It can include runoff from streets, parking lots, and other paved surfaces, as well as sewage that backs up into homes and businesses.
All of these types of wastewater can be harmful to the environment if they are not properly treated. Water carried sewerage systems help to protect the environment by collecting and removing wastewater from homes, businesses, and industries.
