Module 17 — Marine Environment

Sewage and Waste Water

Discharge of untreated sewage is increasingly restricted. Many harbours and estuaries are 'no discharge' zones. Use holding tanks where fitted and pump out at designated facilities ashore.

If the vessel has a marine toilet (heads) that discharges directly, only use it well offshore and away from bathing waters, shellfish beds, and environmentally sensitive areas.

Key Points

  • Use holding tanks in harbours and coastal waters
  • Pump out at designated shore facilities
  • No discharge in harbours, estuaries, or sensitive areas
  • Direct discharge only well offshore if no holding tank
