What is the primary function of a holding tank in wastewater systems?

The primary function of a holding tank in wastewater systems is to store and retain sewage. Holding tanks provide a temporary storage solution for wastewater before it is treated or transferred to another system for further processing. They are particularly useful in areas where immediate treatment is not available or where the volume of wastewater exceeds the treatment capacity. By retaining sewage, these tanks help manage flow rates and prevent overloading of treatment facilities while also allowing for more controlled processing of the waste. This function is essential in maintaining environmental health and ensuring that wastewater is handled in accordance with regulatory standards before being discharged or treated.
