Kei a koe i whakaaro i te āheitanga o ngā putunga nui? Ngaro mīhini he mea nui — ka whakamahia e rātou ngā mea pērā i te wai rere, te wai ki te whakatū i ngā putunga hei noho i ō rātou mahi. Ka wehiwehi te wai rere ki runga i ngā tākiri me ngā paerau hei hanga i te pāpori e whakatū ai i ngā putunga. He hunga nui rawa te puapua mīhini hei whakahaere i ēnei rōpū. Ko tēnei he mea nui, nā te mea, i te wā e kotahi ana ki ētahi atu take kei roto i te whareputunga, ka awhina tēnei ki te whakatau i te āhuatanga o te hā o te kupeke, ko tēhea ki reira te wai rere ka haere, me pēhea te nui o te wai rere ka haere ki tēnā.
Ka taea e ngā pūtomo whakahaere hyd te whakahaere i ēnei momo wai e whakamahi ana i ngā tono hyd, me etahi atu heke nui. Kei a rātou te hiahia ki te whakahaere i te nui o te wai kua whatiwhati, ko tēnā he mea nui mō ngā mīhini e mahi ana i roto i te rāngai. Kāore i ngā pūtomo whakahaere hyd, ka noho te wai hei haere i runga i ōna ake huarahi, ko tēnā he mea nui ki te whakahaere i te rahinga rānei, te haerenga rānei o ngā mīhini. Ko tēnā e whai take ana ki ngā tahae, ki te kore rawa te mahi o ngā mīhini i runga i tō rātou haerenga pai. He mea nui anō hoki te pūtomo whakahaere hyd ki te haumaru. Ka taea e ia te tohe herehere i te āe o te wai i te wā o tētahi āheinga, kia whakaiti te kino rānei, te mate rānei.
Nā ngā pūtango whakahaere wai-āhua e whai take ana, ā, mēnā he tīmatanga rerekē ngā pūtango whakahaere wai-āhua, ka mahi ngā taupu ki tōna ake tikanga. Ko te tuarua tuatahi ko te pūtango whakahaere arahina. -- Ka whakamahi i tēnei pūtango kia tae ai te wai ki te ara tika, me te whakatere iho i te wāhi hei haere. Nō reira, ka kitea tēnei pūtango i roto i ngā putunga, pērā i ngā kōwhatu, nō reira, ka hiahia koe ki te whakahaere i ngā kōwhiringa hanga ki te kotuku, ki te awhe, me te whakawhiti i ngā hua. Ko te tuarua tuarua ko te pūtango whakahaere uaua. Ka whakahaere tēnei pūtango i te uaua o te whenua wai. Ka tiaki i ngā putunga i te whanaketanga uaua e pāngia ana i runga i te uaua e hāngai nei. Ā, inaianei, kei reira te pūtango whakahaere pūnaha. Ko tēnei pūtango te mea e whakatau ana i te wehewehenga o te pūnaha wai e haere ana, ā, ka taea e te kaiwhakahaere te whakahaere i te rahinga i te āheitanga o te putunga.
Nga puera whakamahi — pēnei i ngā kōrero katoa — he hiahia te arohatia me te tirotiro mō te mahi pai, ā, kia mau tonu te wā moe roa. Nō reira, ko te horoi me te tirotiro he mea nui kia kitea ngā tūponotanga, ngā pūnaha wehe ranei, rānei ngā rerekētanga o ia tino momo. Mēnā he rerekētanga i te puera, ka hiahia koe ki te whakatika me te whakatika i a ia i te maha o ngā rā. 'Ka taea te whakatika i te tirohia he hononga here nei, he paoro wehe nei, rānei he kaiwhakaawe nei,' i whakaaetia e te tuhinga. Kia tiakina ēnei momo rerekētanga i te mutunga o ngā rā, ka tohua etahi momo matematea rereke hei whakakore i ngā mate i te whai i te ara matua o te whenua hyd, ka puta ai ngā utu whakahoutia.
Ākona, mā te whakahaere i te hīrahi puta o te wai kōrari, e anga whakamua ana te tūmomo whakahaere ā-hīrahi i te pūtake me te mahi o te rāngai hīrahi. Kei takuwhātia e ia ngā hapa, ā, e whakamanahia ana ko te mea e mahi ai ngā whakawehenga ki ngā wa me ngā pūnaha tika, e tiaki ana i te wharekura i te whanaketanga. Ko te whakahaere tika me te whakatika i te hīrahi puta o te wai kōrari ka tiaki i ngā wharekura anō hoki, ā, ka whakamana i a rātau kia motuhake ake i te whakamahi o te wai hauora. Ka whakamahi i te iti rawa atu o te wai kōrari hei mahi i ngā mahi nui, ā, ka whakaorangia i te moni i runga i te wā, ā, ka whakapakiri i ngā mahi i roto i te whakamahi moni.
