The preferred method for water and sewage service for a subdivision is to ___________.

Extending existing water lines and community sewer lines is the preferred method for providing water and sewage service to a subdivision because it builds upon existing infrastructure. This approach often results in lower costs for both the developers and future residents compared to establishing new systems from scratch. It typically ensures the provision of reliable and safe services while minimizing the environmental impact that could arise from drilling new wells or creating multiple private septic systems. By using established connections, the subdivision can benefit from economies of scale, more effective maintenance procedures, and potentially improved service quality. Additionally, community sewer lines are designed to handle a larger flow of sewage, which helps to manage waste efficiently and ensures compliance with public health regulations. In contrast, the other options may lead to higher long-term costs, environmental concerns, or inadequate waste management solutions.
