Final answer:
Water and sewer services are part of the government function to provide services, which includes public health and sanitation maintenance funded by taxes and user fees.
Step-by-step explanation:
Water and sewer services fall under the function of government to provide services. These municipal services are essential for maintaining public health and sanitation. Municipal governments are responsible not just for providing clean water, sewage, and garbage disposal, but they also manage city facilities, regulate zoning and building regulations, promote economic development, and ensure public safety through law enforcement and fire protection. The provision of these services is typically funded by taxes and user fees from the community, ensuring that all citizens have access to these vital services without direct payment at the time of use.
