How do you size the dosing tank for homes with more than three bedrooms or non-residential buildings?

Sizing the dosing tank properly is critical to ensuring the effective operation of septic systems, especially for homes with more than three bedrooms or non-residential buildings which typically have higher wastewater flows. The correct answer states that the dosing tank must be at least 1.5 times the daily flow. This guideline is crucial because it provides enough capacity to handle peak flows and reduces the risk of tank overflow or inadequate treatment, which can lead to system failure or environmental contamination.

By having a dosing tank with at least 1.5 times the daily flow, the system can accommodate fluctuations in water usage, such as during times of increased activity when more wastewater is generated. This approach helps maintain the system's efficiency and longevity.

In contrast, simply equating the tank size to daily flow or relying on it being twice the daily flow may not sufficiently address peak usage needs and could lead to operational issues. Additionally, having a sizing requirement based on being "any size above 1,000 gallons" neglects the importance of calculating capacity based on actual wastewater generation, which is essential for effective system performance.
