How many additional gallons per bedroom are required for each bedroom beyond 3?

In Connecticut, the standard calculation for septic system design typically includes a base allowance of 3 bedrooms. For each additional bedroom beyond the initial three, the state's regulations stipulate that a specific increase in daily wastewater flow must be accounted for in the design of the septic system.

The correct answer of 125 gallons reflects the additional daily flow requirement per bedroom. This figure is derived from guidelines that aim to ensure adequate system performance and prevent potential overloading of the septic system, which could lead to failures or environmental issues such as contamination.

It's essential to adhere to these specific calculations when planning a septic system, as they are designed to maintain a healthy balance for the infrastructure involved. By using 125 gallons for each additional bedroom, the system can be appropriately sized to handle the projected wastewater flow, ensuring functionality and compliance with health standards.
