How Are Wells Made

To be a successful drilling technician on Haiti is difficult. Subsoil is unfavorable and treacherous. In addition to technical knowledge and experience, a drilling foreman has to have a feeling for machinery as well as for what is happening under the ground. Good assessment is necessary in search of water and the ability to improvise and be patient in solving common problems. Our drilling technicians must get along with almost nothing, must have stamina and motivation to complete unfinished work. Everything takes place in a challenging environment in the heat, dust, under physical and mental strain.
Identifying locations for drilling
  • Wells are made on demand, there is a high demand for making wells
  • They must be accessible to the public and in their vicinity there mustn´t be another similar source or it must be a well for medical or social facilities (schools, orphanage, hospital) - we want to help those in need
Evaluation of new sites
  • We inspect the site on the ground, we assess its necessity, we verify that it is not a private land
  • We assess the presence of water, we consider the complexity of the work, the possibility to access with equipment and risks during drilling – we evaluate topography, terrain and rock
  • On the approved lot we select several specific locations close to each other for more drilling tests, we record GPS coordinates, after a tour of the site we incorporate the location into our work plan
Preparations prior to the commencement of drilling operations
  • Prior to drilling we load the drilling rig, drill rods, drilling, masonry and hand tools, barrels of oil, twenty-foot arm tubes and supplies on the truck
  • We load a three-ton compressor and we set off accompanied by a personal car at the speed of 10-15 km/h to the drilling site
Drilling work
  • With a hydraulic arm we unload the drilling rig from deck and we put it into the working position, we connect the compressor
  • Our rig uses rotary percussion system designed for rocky subsoil
  • First meters go slowly, the rock crumbles, it is often necessary to start with a screw auger
  • We place a steel pipe into the depth of three meters, which prevents gravel and stones from falling into the drill hole
  • We replace the screw drill with a five-inch pneumatic hammer drill (down-the-hole hammer) and we continue drilling
  • The whole so-called drilling string is rotating, the hammer is connected to the drilling machine with drill rods, which are gradually added
  • The diesel generator of the rig ensures vertical displacement of the feed and rotation of the drilling hammer, compressor allows the hammering and forcing the crushed stone through the cavity of the drilling rods to the surface
  • Ratio of successful drillings to the total number of wells is about 1:3 - in cavities there is a risk of burying and loss of a hammer if there are large complications, it is better to stop drilling and move to another location
  • Another risk is a dry or not abundant borehole, the water source can also be salty, contaminated with minerals, our equipment failure can also be a cause of interruption of drilling operations
Fitting of the borehole and preparation for the installation of the pump
  • If we hit the water, we clean up the borehole, we pull out the tools and lag it with plastic pipes
  • We scatter the lagged borehole with gravel, at approximately one-meter depth we create an impermeable layer and we add more soil
  • We assemble shuttering and we mix it with concrete and fit the foot of the pump, after drying of the concrete, we fit the pump
Inspection, service
  • We pass the finished well to a community or association in the presence of a responsible person, we explain the proper use
  • With each additional mission we perform inspection of the wells, it is mostly mechanical wear of the most stressed parts - our wells are used daily by thousands of people
