Taiwan Water Corp. confirmed Tuesday that it expects the fifth desalination plant in Penghu County to be completed by the end of the year, though a government official suggested there was still a hurdle to overcome.

The construction of the desalination plant, initially planned to be completed in May 2018, was later scheduled to be finished by the end of 2018, and that target remains in place, the company said in a statement.

But Public Construction Commission chief Wu Tse-cheng (吳澤成), who was in Penghu on Tuesday to check on the project’s progress, urged Taiwan Water to overcome horizontal directional drilling challenges to complete the plant on time.
