For your Information the Drilling Process:
Step#1: A hydro-geological study to locate where reservoirs or underground water springs exist as well as to establish aquifer depth with enough water in the aquifers to feed/charge/recharge the borehole.
Step#2: Seek local government permit to drill
Step#3: Mobilize and set up of the equipment at the site. To guarantee a straight well in to the ground , the mast is erected using a spirit level to ensure that the machine is set upright.
Step#4: Drilling borehole proceeds using for example an air hammer (DTH) equipement until water has been struck.
Step#5: Insert the casing/ slotted casing at the well bottom, which basically is PVC rim that supports the borehole walls to ensure that the walls do not collapse, leaving a one meter piece of PVC casing protruding above the ground level to ensure that run-off rain or other water and silt does not find its way into the borehole.
Step#6: Pack the circumference of the well on the exterior of the casing using specially graded sand or gravel that serves as a water filter.
Step#7: Build a raised slab around the borehole, which ensures that any sitting water flows away.
Step#8: Test pumping of the borehole, a process which allows for measuring how much water the borehole is yielding versus the recharging rate. Ensure water is continuously pumped out of the borehole for a sustained period. Helps determine pump to be installed.
Step# 9: Install pump
Step#10: Maintenance Contracts: Maintaining borehole pumps is desired a result of for example a declining yield, or dirty water production. This may include “flashing”/de-silting and/or replacing worn out pumps, burnt out motors and/or broken pipes, cables or control panels.
