Pērā i ngā taputapu ahumahi kē atu, me tiaki tonu te mīhini whakairo taiaho anga waea pūkoro mō te whakamatao wai, ā, ko tētahi o ngā mahi tiaki nui ko te whakawhiti i te wai. Kāore te auau whakawhiti wai i te pumau, ā, ka whakawhirinaki pea ki te taiao mahi o te mīhini whakairo taiaho anga waea pūkoro mō te whakamatao wai. Pērā i te taiao mahi o te mīhini whakairo taiaho anga waea pūkoro mō te whakamatao wai, ka taea te whakawhiti wai i ia 3 marama. Mō te rūma hauhautanga me te kounga taiao teitei, ka taea te auau i ia hawhe tau.
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.
