True or False: Dosing tanks using pumps must have designed reserve capacity to allow adequate repair time in case of a pump failure.

Having a designed reserve capacity in dosing tanks that utilize pumps is crucial for ensuring the system remains operational during maintenance or repair. This reserve capacity acts as a buffer that allows for the accumulation of effluent, providing time to repair or replace a malfunctioning pump without causing system failure or oversaturation.

In systems where pumps are tasked with moving effluent, the reserve capacity is integral for preventing backflow or backup in the system if a pump fails. It ensures that there is always some extra volume available to accommodate the normal inflow while a repair is being undertaken, thus safeguarding both the system's performance and the environment from potential contamination.

Therefore, it is accurate to state that dosing tanks must indeed have this reserve capacity, supporting the idea that effective system design incorporates maintenance considerations to handle unexpected pump failures.
