What is the minimum required treatment capacity in gallons per day for residences with 1-10 bedrooms?

The minimum required treatment capacity for residences with 1-10 bedrooms is set at 400 gallons per day (gpd). This standard is based on typical water usage patterns associated with the number of bedrooms in a home, where a higher number of bedrooms is correlated with increased wastewater generation.

For residences, it's important to ensure that the septic system can handle the expected effluent volume to maintain system functionality and prevent backflow or overflow issues. In this case, 400 gpd is determined to be a sufficient capacity for residents living in homes with up to 10 bedrooms, as it accommodates standard usage without overwhelming the system. This requirement helps ensure public health and environmental safety by ensuring that wastewater is adequately treated before being discharged into the environment.

Higher values, such as 500 gpd, 750 gpd, and 1000 gpd, are typically reserved for larger facilities or unique situations that demand greater capacity, reflecting different regulations or guidelines for different types of structures.
