Discharge of Sewage and Waste (cont.)
A marine sanitation device treats waste with special chemicals to kill bacteria before the waste is discharged.
- To be approved, an MSD must meet the requirements as given in the Vessel Pollution and Dangerous Chemicals Regulations.
- MSDs are installed between the toilet and the “Y” valve.
- The “Y” valve must be secured to prevent accidental illegal discharge. This can be done by placing a lock or non-reusable seal on the“Y” valve or by taking the handle off the “Y” valve.
- Only treated sewage from an approved MSD may be discharged directly overboard. The treated sewage must meet the standards as given in the Vessel Pollution and Dangerous Chemicals Regulations.
- The standard you must meet depends on whether you are operating in a “designated sewage area” or in an area that is not a “designated sewage area.”
- The sewage must be effluent (liquid) and not contain any visible solids.
