Ma Savone is five kilometres south of Bombardopolis not far from the road to Baie - de - Henne. The well is located near the elementary school. The original source of water for the local residents was a stream four kilometres away with a bad quality water.

The borehole is 58 meters deep, the water column reaches 38 meters. Drilling was very complicated. The well is fitted with a foot pump Vergnet.

The drilling mission, during which the well Eva was built, was financially supported by the St. Elizabeth College of Health and Social Work.
