Enhancing Ship Sewage Management: Challenges and Recommendations for the Technical Policy

While the 'Technical Policy for Ship Water Pollution Prevention and Control' acknowledges the importance of managing both black water and grey water discharge from ships, its lack of legal enforceability poses a challenge. The policy recommends gradually implementing grey water control measures, including onboard collection and storage in designated devices and closing drainage valves in ecologically sensitive areas like drinking water source protection zones. These measures aim to prevent sewage from contaminating water bodies. The policy also stresses the importance of record-keeping for implemented control measures. However, its non-binding nature may hinder its effectiveness. Transitioning this policy into legally enforceable regulations is crucial for significantly reducing ship-based pollution and safeguarding the health of our oceans.
