Ko te hanganga o tētahi pā wai hiko tētahi o ngā mahi tino nui, tino uaua hoki a te tangata, he tohu i te pūkenga hangarau me te whakapau kaha ki te pūngao pumau. Ehara i te mea ko te pupuri wai anake te mahi a ēnei hanganga nunui; ka hurihia e rātou te mana o ngā awa e rere ana hei hiko ma, ka whakamārama i ngā tāone me te whakakaha i ngā ahumahi. Ko te tukanga o te hanganga o tētahi he huinga maha-wāhanga o te matawhenua, te hangarau ā-iwi, me te pūtaiao taiao.
Wāhanga 1: Te Mahere – Te Whakamahere me te Whai Huatanga
I mua noa atu i te taunga o te koko tuatahi ki te whenua, he maha ngā tau e whakatapua ana ki te whakamahere tupato. Ka whakahaerehia e ngā miihini, ngā tohunga whenua, me ngā kaitiaki taiao he rangahau whānui.
Kōwhiringa Pae: Ko te wāhi tino pai e whakakotahi ana i te rere o te wai kaha, pono me te āhua whenua e tika ana, pērā i te awaawa hohonu, hei hanga i tētahi puna wai nui. Me pumau te toka o raro hei tautoko i te taumaha nui o te tāhuna.
Aromatawai Pānga Taiao me te Pāpori (ESIA): Ka arotakehia e tēnei taahiraa nui ngā hua ka puta. Ka arohia te nekehanga o ngā hapori, te pānga ki ngā rauropi ā-rohe me te hekenga ika, me te tiaki i ngā wāhi hītori, ngā wāhi keri whenua rānei. Ka whakawhanakehia ngā rautaki whakaiti i te kino, pērā i te hanga arawhata ika, te waihanga rānei i ngā nohoanga kararehe hou, i tēnei wāhanga.
Hoahoa me te Hangarau: Ka whiriwhiria te momo tāhuna i runga i ngā āhuatanga o te papa. Ko tētahi hoahoa noa ko te tāhuna taumaha, he pakitara raima nui, tika e whakawhirinaki ana ki tōna ake taumaha hei ātete i te pēhanga wai. Ko tētahi atu ko te tāhuna parepare, i hangaia mai i te oneone me te toka kua whakakīia, e whakamahia ana mō ngā awaawa whānui.
Wāhanga 2: Te Whakatakoto i te Tūāpapa – Te Whakarite i te Pae me te Hurihanga
Kia oti te mahere te whakatakoto, ka tīmata te whakarerekētanga ā-tinana o te whenua.
Te Whakarite i te Papa: Ka whakawāteahia ngā ngahere, ā, ka taea te uru atu ki te wāhi hangahanga mā te hanga rori me ngā piriti. Ka keria te papa o te tāhuna kia pakari ai te tūāpapa.
Te Hurihanga Awa: He taahiraa nui hei waihanga i tētahi wāhi mahi maroke. He maha ngā wā ka tutukihia tēnei mā te hanga kauhanga rangitahi, awa rānei huri noa i te taha o te papa hanga hei huri i te rere o te awa. Ka hangaia ngā pā wai—he ārai wai rangitahi—hei tiaki i te wāhi hanga matua mai i te awa kua hurihia.
Wāhanga 3: Te Aranga Mai o tētahi Tangata Nui – Te Hanganga Matua
Koinei te wāhanga tino kitea, tino kaha hoki, e uru ana ki te nekehanga o te tini o ngā rauemi.
Te Ringihia o te Konukuraiti (mō ngā Pānga Taumaha): Mō ngā pānga konukuraiti nunui pērā i te momo taumaha, ka mahia te hanganga i roto i ngā poraka takitahi, e hono tahi ana. Ka whakauruhia ngā paipa whakamatao ki roto i te konukuraiti hei whakahaere i te wera e puta ana i te wā e whakamaroke ana, hei ārai i ngā kapiti ka kino pea te hanganga. He mahi tonu tēnei, ā, ka roa pea mō ētahi tau.
Te Hanganga o te Parepare (mō ngā Pā Tāone/Toka Whakakī): Ka whakatakotoria ngā paparanga uku ā-roto me ngā toka kua whakakīia, ka hurihia kia puta he pūtake matotoru, ā-wai. Me whai rauemi tonu mai i ngā keri kohatu tata mō tēnei tikanga.
Te Hanganga o te Ara Pupuri Wai: I taua wā anō, ka hangaia te ara pupupuri wai, te takirere haumaru nui o te tāmi. Mā tēnei hanganga ka taea e te wai nui te karo haumaru i te tāmi i te wā ua nui, ka ārai i te waipuke kei taupokina, ā, ka pakaru kino.
Wāhanga 4: Te Ngākau o te Pūnaha – Te Tāutanga o te Pūnaha Hiko
I te pikinga ake o te tāhuna, ka tīmata te mahi i te whare hiko.
Penstocks: Ka tāutahia ngā paipa rino nunui mā roto, mā te taha rānei o te tāhuna, he mea hanga hei kawe wai mai i te puna wai me te kaha nui.
Ngā Tāpine me ngā Pūkaha Hiko: I roto i te whare hiko, ka tukuna e ngā pene te wai ki runga i ngā mata o ngā tāpine nunui, ka huri ai. Ka honoa ēnei tāpine ki ngā pūkaha hiko, ka huri i te pūngao miihini hei pūngao hiko. Ko te momo tino noa ko te tāpine Francis, he pai mō te whānuitanga o ngā rere me ngā pēhanga wai.
Wāhanga 5: Te Pupuri me te Whakatūnga
Kia oti te hanganga matua, kia tāutahia hoki ngā tāpine, ka tae mai te wā o te pono.
Te Ārai: Ka āta katihia ngā kauhanga whakawhiti, ā, ka tīmata te awa ki te whakakī i te puna wai i muri i te tāhuna. Ka āta tirotirohia tēnei tukanga, ā, ka āta tirohia hoki, nā te mea ko te wai e piki haere ana ka pēhi i te hanganga hou mō te wā tuatahi.
Te Whakatūnga: Ina eke te puna wai ki tōna taumata mahi, ka tukuna te wai mā roto i ngā pene rakau hei huri i ngā tāpine. Ka honoa ngā whakaputa hiko ki te whatunga hiko, ā, ka tīmata mana te tipu hiko wai ki te tuku hiko.
He Taonga Tuku Iho o te Mana me te Kawenga
He whakatutukitanga nui te otinga o tētahi pā wai hiko. Ka whakaratohia he puna hiko hou mō te wā roa, ka whakaiti i te whakawhirinaki ki ngā wahie pūmua, ā, ka taea hoki te tuku i ētahi atu painga pēnei i te whakahaere waipuke, te whakamakuku, me te whakangahau.
Heoi anō, kāore e kore he taupatupatu nui. He hohonu, he pumau hoki ngā pānga taiao me te pāpori—mai i ngā pūnaha rauropi kua whakarerekētia ki ngā hapori kua nekehia atu. Nō reira, ko te hanganga tāhuna hou he mea nui ki te whakamahere me te whakaiti i te kaha o te taiao, me te hiranga o te hangarau. Ko te tāhuna hiko wai kua oti te hanga he tohu mō tō tātou kaha ki te whakamahi i te mana o te taiao, e whakamahara ana i a tātou ki te taurite i waenga i te ahunga whakamua me te tiaki.
