Controlling Ship Sewage Discharge: A Look at China's Technical Policy & Enforcement

China's 'Technical Policy for Ship Water Pollution Prevention and Control' provides guidance on managing sewage generated on ships, encompassing both black water (from toilets) and grey water (from sinks, showers, etc.). The policy emphasizes a phased approach to grey water control, recommending the use of onboard equipment for sewage collection and storage.

To minimize environmental impact, the policy highlights the importance of closing drainage valves when ships are in areas where sewage discharge is prohibited. This includes sensitive zones like drinking water source protection areas. Additionally, the policy underscores the need for meticulous record-keeping related to these control measures.

While the 'Technical Policy for Ship Water Pollution Prevention and Control' offers valuable guidance, it's crucial to acknowledge its limitations. As a guiding document, it lacks legal enforceability, which may pose challenges in its effective implementation.
