To assure a steady supply of water at the orchard, we started digging a deep well today, September 25, 2020. Mang Boy, the digging contractor, estimates that their rate of progress will be about a meter per day.
Based on the depth of the driven pipe for the water pump nearby, we expect to finish digging at a level of about 16 - 17 meters below the ground. This job should take about 3 weeks, as the manual digging becomes tougher as the well gets deeper.
Their digging and concrete lining method are very interesting. Once they have dug about a meter, they place a steel form then fill the sides of the well with mortar.
This step-by-step digging/lining with mortar continues downward until a good level of water is reached. In the future, when the water level subsides (especially in summer), they can easily extend the well deeper and the concrete casing further, while maintaining a constant well diameter.
