Nutrient pollution from emptying septic tank systems into the ocean is proving to have a negative effect on coral and marine life in the surrounding reefs, leading to excess algae growth on the coral bed – the “solution to pollution is no longer dilution.”

Thanks to permaculturalist Norm van’t Hoff, the RARCC and Papua Diving are constructing a series of newly designed septic tanks and leach fields, making use of papaya trees, banana trees, and vetiver grass to soak up the nutrients.

A new public toilet and septic tank system is being installed for a woman on the island of Waigeo, to encourage a unique source of income through the expanding tourism industry, other than the standard guesthouse, fishing, and birding venues.
