Water and wastewater management involves the collection, treatment, and distribution of water for various uses. Water is essential for drinking, agriculture, and industry, while wastewater refers to used water that comes from homes, businesses, and factories. Proper management ensures that clean water is available and that wastewater is treated to protect public health and the environment. The treatment process for wastewater typically includes several stages, such as screening, sedimentation, and filtration. These processes remove contaminants and harmful substances before the water is released back into the environment or reused. Effective water and wastewater systems are crucial for sustainable development and maintaining healthy ecosystems.
