Onboard Sewage Treatment


The Sani-Loo® Onboard Sewage Treatment System
The cost-effective solution to complying with Australian government requirements for the treatment of sewage in a marine environment (Grade C).

Sani-Loo® is the perfect marine sanitation solution to your boat toilet and marine waste treatment needs. It is designed and manufactured here in Australia by Sani-Loo Pty Ltd. We began manufacturing the Sani-Loo® Onboard Sewage Treatment System to overcome many of the problems in existing systems such as high prices and malfunctioning electronics.

The Sani-Loo® boat sewage treatment, marine sanitation system treats macerated toilet waste as it enters the treatment tank. A chemical is added to the treatment tank that sanitises the waste to 99%. The waste is then pumped directly overboard in most areas or to a holding tank (if in a nil discharge area) ready for discharge overboard when the vessel is in an area where treated sewage can be discharged. The alternative is to empty the holding tank at a marina pump out.

Holding tanks need to be vented correctly for odour free containment. The marine sanitation system will connect to electric macerating toilets. If you have an electric toilet installed, it is a simple matter to connect the Sani-Loo®. If you’re looking for a reliable supplier of marine sanitation system with no-nonsense functionality and sensible pricing, you’ve come to the right place.
