Mena kāore e taea e te pūnaha whakamatao wai e whakamatao ana i te taputapu tapahi taiaho kirihou te whakamatao tika, tera pea nā:
1. Kua kapi te taupoki puehu i te puehu, nō reira kāore i te pai te hauhautanga o te pūnaha whakamatao taiaho. E taunakihia ana kia tangohia te taupoki puehu i ia wā, kia horoia hoki;2. Kei roto i te wai e rere ana ngā matū ke, ka puta ai te wai e piri ana ki roto i te porowhita wai. I tēnei wā, whakamahia te wai parakore, te wai ma rānei hei wai e rere ana, ā, hurihia i ia 3 marama;
3. He iti rawa te mana e tukuna ana. E taunakihia ana kia tāpirihia he mea whakau hiko;
4. Kua pakaru te pūmana whakahaere pāmahana o te pūnaha whakamatao wai, ā, kāore e taea te tohu i te pāmahana wai. Mēnā koinei te take, me rapu he mea hou mai i te kaiwhakarato whakamatao.
Whai muri i te 19 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.
