This Code of Practice W 115 provides information on the usual drilling methods and their applications. In addition, it contains references to possible faults during water development work, which may have consequences for operation, maintenance (regeneration, rehabilitation) and dismantling. As a summarising abstract it shall serve anyone involved with drilling operations as starting point for projectrelatedconsiderations.
