Water sanitation refers to the processes and systems that ensure safe and clean water for drinking, cooking, and personal hygiene. It involves the treatment of wastewater and the management of water resources to prevent contamination. Proper water sanitation helps reduce the spread of diseases caused by pathogens found in contaminated water. Effective water sanitation practices include the use of water treatment plants, sewage systems, and filtration methods. These systems work together to remove harmful substances and ensure that water is safe for public use. Access to clean water is essential for maintaining public health and promoting overall well-being.
