Ki te kore te pāmahana o te wai e heke i muri i te mahi a te mīhini whakamatao hau tapahi taiaho hiako mō tētahi wā, tera pea:
1. Kua pakaru te pūmana pāmahana o te waeine whakamatao hau, nō reira kāore e taea te whakahaere i te pāmahana wai;2. Kāore i te rawaka te kaha whakamatao o te waeine whakamatao hau kua rite rawa;
3. Mena ka puta tēnei raruraru i muri i te whakamahinga o te pouaka whakamatao mō tētahi wā, koinei pea:
A. He paru rawa te whakawhiti wera o te waeine whakamatao hau;
B. He turuturu te hauhautanga i roto i te waeine whakamatao hauhautanga;
C. He makariri rawa, he wera rawa rānei te taiao mahi.
Kia kitea te take tuturu, ka taea e ngā kaiwhakamahi te rapu awhina mai i te kaiwhakarato pouaka whakamatao.
Whai muri i te 18 tau o te whanaketanga, ka whakatūhia e mātou he pūnaha kounga hua pakari, ā, ka whakaratohia he ratonga whai muri i te hoko kua tino whakapumautia. Neke atu i te 90 ngā tauira pouaka whakamatao wai paerewa me te 120 ngā tauira pouaka whakamatao wai hei whakaritenga. Me te kaha whakamatao mai i te 0.6KW ki te 30KW, ka taea te whakamahi i ā mātou pouaka whakamatao wai hei whakamatao i ngā momo pūtake taiaho rerekē, ngā mīhini tukatuka taiaho, ngā mīhini CNC, ngā taputapu hauora, ngā taputapu taiwhanga me ētahi atu.
