E ai ki ngā wheako o S&A Teyu, kei raro nei ngā take pea:
1. Kāore i te pai te marara o te wera o te pūnaha whakamatao wai ahumahi, ā, tera pea nā te kore mahi a te pā whakamatao, te raruraru puehu nui me te pāmahana teitei o te taiao;2. Kāore te pūnaha whakamatao wai ahumahi e whakahaerehia ana e ai ki te tikanga. Hei tauira, kāore te ngaohiko whakauru i te ōrite; kāore te hauhautanga i whakamahia i te ōrite; kāore he horoinga auau o te pūwhakamātao me te tauera puehu me ērā atu mea. Ka taea e ēnei katoa te arahi ki te iti o te whai huatanga o te whakamatao o te pūnaha whakamatao wai ahumahi.
Hei karo i te iti o te whai huatanga o te whakamatao, e taunakihia ana kia mahia he tiaki auau mō te pūnaha whakamatao wai ahumahi.
Whai muri i te 17 tau o te whanaketanga, ka whakatūria 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.
