How are industrial water use and a private well regulated if Guatemala has no water law?

Guatemala has no general water law, a '40-year constitutional debt', and no systematic national registry or monitoring of groundwater extraction; municipalities run the urban systems and indigenous communities operate their own. For a plant, supply from its own well is handled today through municipal licenses and MARN environmental instruments, with no national extraction fee. There is no national public price list for drilling or for licenses: the regime and the cost per meter have to be established municipality by municipality.
