When it comes to cluster septic systems, there isn’t a one-size-fits-all answer for how many homes they can service. The capacity depends on several factors, including the amount of available land for drainage, the volume of wastewater produced, and local regulations. While clusters can be designed to handle a large number of homes, the specific design must align with county regulations regarding location, treatment amount, system limits, and the geographic characteristics of the property.

These factors vary widely across the United States, making it essential to tailor the system to your community's unique needs. For the best results, it's crucial to work with experts who understand these regulations and can design a system that meets all requirements.
