What characterizes a holding tank in wastewater management?

A holding tank in wastewater management is specifically designed for temporary storage of sewage and wastewater. This characteristic is essential as the primary function of a holding tank is to collect wastewater until it can be transported for treatment or disposal. Unlike treatment systems that process sewage into clean water or use chemicals to break down waste, holding tanks do not treat the wastewater—they simply hold it.

The temporary nature of a holding tank is critical because the stored wastewater must be regularly emptied to prevent overflow and potential environmental issues. This distinguishes it from permanent storage solutions, which are designed for ongoing containment rather than for temporary collection before disposal. Thus, the defining attribute of a holding tank is its role in managing sewage temporarily while awaiting further processing or removal.
