Me whakawhiti tonu te wai e rere ana i roto i te pūnaha whakamatao wai e whakamatao ana i te mīhini tapahi reihi kiriaku. Ina mahi te pūnaha whakamatao wai, ka ngāwari te poke i te taiao, ka ārai i te awa wai o roto. Nō reira, e taunakihia ana kia whakawhitia te wai e rere ana i ia wā (ia 3 marama he pai) me te whakamahi i te wai parakore, te wai ma rānei hei wai e rere ana.

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.
