Common questions we get about the OASIS…
To build an OASIS, there are a lot of different expenses that add to the final cost: purchasing a 40 foot shipping container, wages to local laborers for their work as we train them to fabricate and weld, plumbing supplies, solar panels, a solar water pump, epoxy potable water tank liner, etc. etc... All this being said, our financial goal to build an OASIS is to stay under $10,000. We want to stay under the 10K threshold because, in our research, that is the average cost to drill a new well for a community.
When we build the first OASIS on location in Soroti, Uganda in the winter of 2019, it will be serving a village of 150 to 200 people.
The OASIS connects to existing wells. We’ve found this source to be the cleanest and most reliable water source in villages we seek to serve. Two solar panels will provide power to an electric pump placed in the community’s well alongside the existing hand pump.
The OASIS does not collect rain water. The current OASIS design consists of a closed water tank with a potable epoxy liner, keeping it sealed off from the elements to minimize contamination from birds and other wildlife, ensuring clean storage of fresh ground water that is replenished daily.
Good question! Sewage, or ‘black water’, is discarded separately to a septic field to be filtered naturally and safely in order to not contaminate ground water near the existing well. ‘Grey water’, or water from the sinks and showers will be collected and used to irrigate crops and replenish stock tanks for livestock.
