The new facilities at St Chris Sipii Primary School in Bolave, Bana District, include two toilets, 17 water catchment systems and 30 water tanks.
The K100,000 project was initiated by the Bolave people who successfully applied for an Australian government grant after raising more than K8,000 in the community.
The new facilities will reduce reliance on mountain water sources, which are often depleted during dry season and can be muddy and contaminated in rainy periods.
