What is the purpose of a retention system in sewage management?

The purpose of a retention system in sewage management is to store sewage temporarily until it can be pumped out. This system is crucial for managing waste effectively on vessels, especially when in areas where discharge into the water is prohibited or not feasible. The retention system ensures that sewage is contained within the vessel until it can be properly disposed of at an appropriate facility, thereby preventing environmental contamination and adhering to regulations regarding the discharge of waste.

Maintaining this temporary storage capability is vital for both sanitation and compliance with maritime waste management standards, which mandate that sewage must either be treated or disposed of correctly. This system is particularly important in recreational or commercial vessels that often operate in sensitive marine environments.
