If both a holding tank and treatment system are installed, is it recommended to treat sewage before storing in the holding tank when in a no-discharge zone?

In a no-discharge zone, the primary concern is to prevent any sewage from being released into the water body, as it could cause environmental harm. The recommended practice is to not treat sewage before storing it in the holding tank because treatment processes may lead to by-products that could complicate the subsequent handling, storage, and disposal of the treated effluent.

The main role of a holding tank in such zones is to safely contain waste for later removal and appropriate disposal at a designated facility where sewage can be managed effectively. If treatment occurs prior to storage, it may create issues with compliance and waste management practices, which are crucial to adhere to within these protected areas.

While some might question whether treatment should ever occur, it’s essential to recognize that the purpose of the holding tank is to temporarily store raw sewage until it can be removed. Conducting treatment before storage could diminish the efficiency of the subsequent handling and disposal processes, which is not ideal in a no-discharge situation.

In summary, not treating sewage prior to holding storage aligns with the guidelines aimed at ensuring proper waste management in no-discharge zones.
