Conserving, collecting and replenishing

A little context
Bali’s natural freshwater aquifers are at record lows of less than 20% and researchers warn the island is heading towards ecological crisis. High demands for fresh water in densely populated urban and tourism areas, have seen water supplies diverted from vital agricultural areas, and coastal aquifers suffering irreversible leaking of saltwater into groundwater. 

The need to harvest groundwater and recharge water into the soil is critical. We are playing our part, on our campus with a fresh set of water projects.

Current projects
Part one of a major water harvesting system was designed and installed by High School students in 2022. Collecting water from the roof of our biggest building, The Arc, as well as incoming groundwater from the carpark and road. Water can recharge through the collection system with overflow being contained in our first deep recharge well. At 7 meters deep, the well is the first of 3 to be installed in 2024. Further overflow is collected in tanks for reuse. Smaller biopores around Heart of School also play a part in groundwater harvesting. 

Impacts so far
1 rainwater harvesting drain and recharge system
2 water recharge well already installed. These are 7-8 meters deep and 1 more will be installed in 2024. The total amount of water recharged through the system will be monitored via a sensor and published (coming soon)
8 water storage tanks installed with  88,000L storage capacity
6 biopores installed
