Which systems are included under Utility Systems?

Utility systems fundamentally refer to the essential services that provide the basic needs for a community. The correct answer encompasses a comprehensive selection of systems that are crucial for public health, convenience, and the overall functioning of urban and rural areas.

In this instance, the combination of electrical systems, water systems, and wastewater systems is particularly significant. Electrical systems are necessary for power distribution and usage; water systems ensure a reliable supply of safe drinking water; and wastewater systems are essential for the proper treatment and disposal of sewage, thereby safeguarding public health and the environment. These three systems together create a vital framework for municipal services that directly impact the quality of life for residents.

Other options may include components that are important but do not represent the core utility systems as comprehensively as the correct choice does. For instance, while gas and oil systems are important for energy provision, and telecommunications are critical for communication, they do not cover the broader essential services provided by water and wastewater systems, which are fundamental to community sustainability and public health.
