Soaps from boat washing, sinks and showers are more harmful that those at home because they have not been treated in a sanitary sewer before being discharged overboard.
WHAT CAN BOATERS DO TO REDUCE GRAY WATER DISCHARGE?
- Use shore-side facilities - showers, sinks, laundry
- If not available, save showers, laundry, and dishwashing for home
- If possible, install holding tanks for gray water
- Use water saving devices such as low pressure showerheads to conserve water
- Use more "elbow grease" and as little cleaning product as possible.
- Try to skip the boat wash. Unless you need to rinse the salt water, wiping the boat down with a damp cloth will suffice.
- Use tarps or canvas boat covers to keep boat clean between trips and reduce the amount of cleaning you need to do.
- Use only biodegradable, non-phosphate, and less toxic laundry detergents, soaps, drain openers, cleaners etc.
- Conserve water and use water saving devices such as low volume showerheads.
