Best Practice Sewage


  • Encourage members and students to use marina/shore side facilities whenever possible
  • Use environmentally friendly low phosphate toilet cleaners on board
  • Educate students on the products to use and the procedures to follow
  • Use recycled toilet paper as this breaks down more quickly than regular paper
  • Check out the Pump Out Directory for where to empty your holding tank
  • Educate students and encourage them to follow The Green Blue’s Code of Conduct
  • Encourage your local marina to install pump out facilities and teach your students how to use them
  • Check out the marine toolkit for more advice

Coastal Specific

  • Use holding tanks or a portable toilet if you regularly sail in poor tidal flushing areas such as estuaries, inlets and crowded anchorages
  • Empty holding tanks only when more than 3 miles offshore in the open sea where waste will be quickly diluted and dispersed by wave action and currents.
  • When visiting new sites give consideration to the environmental sensitivity of the area before using your sea toilet
  • Fit a holding tank in your boat, some European countries require it by law

 Inland Specific

  • When using chemical toilets plan ahead where you will empty these as they use toxic substances that only a few pump out facilities will accept. Never empty down a drain, always dispose of into an appropriate sewage system
  • Find out the regulations of the waterways you visit before setting off
