Holding tanks should be allowed to flush for 30 minutes to ensure that any accumulated materials have sufficient time to be flushed out properly and thoroughly. This duration is typically considered optimal as it balances effective cleaning with system efficiency. Allowing too little time may result in incomplete flushing, leaving residues behind, while excessively long flushing periods can waste water and may not provide any additional benefit. The 30-minute guideline helps to ensure that the holding tanks are emptied as effectively as possible, thus maintaining operational efficiency and hygiene standards.
