What is the maximum flush volume allowed for commodes in facilities using holding tanks?

The maximum flush volume allowed for commodes in facilities using holding tanks is set at 6 gallons or less to ensure that the system can efficiently handle wastewater without overwhelming the holding capacity. This regulation helps in managing the volume of effluent produced, as holding tanks have a limited capacity and can fill up quickly if high-flush toilets are used.

By limiting the flush volume, it also promotes water conservation, reducing unnecessary water usage while still maintaining adequate sanitation. Lowering the flush volume helps in minimizing the frequency of pumping and maintenance required for holding tanks, ultimately leading to better system performance and longevity. These standards are typically enforced as part of state regulations related to septic systems and wastewater management to ensure environmental protection and public health safety.
