Extending existing water lines and community sewer lines is the preferred method for providing water and sewerage service in a subdivision for several key reasons.

Firstly, this approach ensures that the infrastructure is centralized, which typically results in more efficient management of water quality and waste treatment. Community systems allow for a consistent supply of potable water and effective sewage handling, which can be monitored and maintained by a utility provider or local government, thereby reducing individual homeowner responsibility and the potential for system failures.

Secondly, extending existing lines leverages existing infrastructure, which can be more cost-effective than installing individual systems for each home. Individual septic systems or wells can lead to increased costs for homeowners, not only in installation but also in maintenance and regulatory compliance compared to community systems.

Additionally, having a centralized water supply and sewage system reduces the environmental impact as it minimizes the risk of groundwater contamination that can occur with multiple individual septic systems and wells, which may not be properly maintained.

Furthermore, community systems are generally more sustainable in terms of resources and energy use. They often utilize advanced treatment techniques that are more difficult and expensive to implement on an individual household basis.

In summary, the choice of extending existing water and community sewer lines fosters better environmental stewardship, economic efficiency, and overall service reliability
