of boreholes and vells for water exploitation

Achieve boreholes reinstatement in service by:
  • doubling the filtration column where damage in the casing is found based on geophysical studies;
  • desanding of wells to remove sand decanted in well, and formation of backward filter through different pumping processes;
  • chlorination of wells for water desinfection;
  • experimental pumping (efficiency test) to determine the operational flow;
