Answer:
4.The scarcity of water is increasing day by day so better management is something that can help a lot. It will provide water to all thereby accomplish their necessary needs and also less water will be wasted which in turn is a benefit. Also water needs will be easily met especially in areas where it was not.
5.The main function of a sanitary sewer system is to protect water quality and public health. A series of underground pipes and manholes, pumping stations, and other appurtenances convey sewage from homes, businesses and industries to wastewater treatment plants where it is cleaned and returned to the environment
