Boreholes they say can last for many years. However, all good things they say shall not last forever. With the right maintenance culture the life span of boreholes can be prolonged. Global Engineering & Drilling Ghana Limited deploys series of techniques in rehabilitating old borewells. First and Foremost, we diagnose boreholes that demand rehabilitation. We deploy camera in-check apparatus to identify viability.
We go ahead to inject hexametaphosphate solutions to detach clogs from the walls of the borehole. We then apply a pump test to determine its yield and chlorinate the well. Finally, GEDGhana blows the well and sometimes conduct a water quality test analysis to determine potability.
