I kōrero mai tētahi kiritaki kāore te pāmahana wai o tana pouaka whakamatao hau i tohu i tētahi uara pumau i muri i tana tahuritanga. I ētahi wā ka piki ake te pāmahana o te wai, ā, i ētahi wā ka heke iho. Nā te mea kei raro te pouaka whakamatao hau i te aratau pāmahana atamai. I raro i tēnei aratau, ka whakarerekē te pāmahana o te wai i a ia anō i runga i te pāmahana taiao (ko te tikanga he 2 nekehanga C te iti iho i te pāmahana taiao). Mena ka hiahia ngā kaiwhakamahi ki tētahi pāmahana wai pumau, ka taea e rātou te huri ki te aratau pāmahana pumau i te tuatahi, kātahi ka whakatakoto i te uara pāmahana kia rite.
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.
