Taipitopito Hua

Ko te whatunga rerenga wai i roto i ngā kaupapa tiaki wai he pūnaha e whakamahia ana hei whakaheke i ngā wai i roto i ngā whare tiaki wai pērā i ngā tāhuna, ngā puna wai, me ngā pareparenga. Ko tana mahi matua he whakaheke i te wai turuturu i roto i te tinana tāhuna me ngā pareparenga, he whakaiti i te taumata o te wai whenua, he whakaiti i te pēhanga wai pūwero, kia mau ai te pumau me te haumaru o ngā hanganga kaupapa tiaki wai. Hei tauira, i roto i tētahi kaupapa tāhuna, ki te kore e taea te whakaheke i te wai turuturu i roto i te tinana tāhuna i te wā tika, ka noho te tinana tāhuna ki te āhua mākū, ka heke te kaha kutikuti o te rauemi tāhuna, ā, ka piki ake ngā tūponotanga haumaru pērā i te horo o te tāhuna.

Te Mātāpono o te Waikeri
- Ko te whatunga rerenga wai i roto i ngā kaupapa tiaki wai e whakamahi ana i te kaupapa o te rerenga wai ā-papatipu. I roto i te tinana o te tāone, i te pareparenga rānei, nā te rerekētanga o te taumata wai, ka rere te wai mai i tētahi wāhi teitei (pērā i te wāhi mimiti wai i roto i te tinana o te tāone) ki tētahi wāhi iti (pērā i ngā kōhao rerenga wai, ngā arawhata rerenga wai) i raro i te mana o te ā-papatipu. Ina uru te wai ki ngā kōhao rerenga wai, ki ngā arawhata rerenga wai rānei, ka ringihia ki tētahi wāhi haumaru i waho o te tinana o te tāone, pērā i te awaawa o raro o te puna wai, i tētahi puna rerenga wai motuhake rānei, mā roto i tētahi pūnaha paipa, i tētahi awaawa rānei. I taua wā anō, mā te noho o te paparanga tātari ka taea e te hanganga oneone te noho pumau i te wā o te tukanga rerenga wai, ka karo i te ngaronga o te oneone i roto i te tinana o te tāone, i te pareparenga rānei nā te rerenga wai.

Ngā tono i roto i ngā kaupapa tiaki wai rerekē
- Ngā Kaupapa Tāwharau:
  - I roto i tētahi tāhuna raima, hei tāpiritanga ki te whakatū i ngā kōhao waikeri me ngā ara waikeri, ka whakatūria hoki ngā whakaurunga waikeri ki te wāhi e pā ana ki te tinana o te tāhuna me te turanga hei whakaiti i te pēhanga hiki i runga i te turanga o te tāhuna. Ko te pēhanga hiki he pēhanga wai ki runga i te raro o te tāhuna. Ki te kore e whakahaeretia, ka whakaitihia te ahotea pēhanga whai hua i raro o te tāhuna, ā, ka pā ki te pumau o te tāhuna. Mā te tango i te wai turuturu mai i te turanga o te tāhuna mā roto i te whatunga waikeri, ka taea te whakaiti i te pēhanga hiki. I roto i tētahi kaupapa tāhuna whenua-toka, he uaua ake te whakatakotoranga o te whatunga waikeri, ā, me whai whakaaro ki ngā āhuatanga pēnei i te urunga o te rauemi o te tinana o te tāhuna me te pari o te tinana o te tāhuna. I te nuinga o te wā, ka whakatūria ngā tinana waikeri poutū me ngā tinana waikeri whakapae ki roto i te tinana o te tāhuna, pēnei i ngā pou onepu waikeri kua takaihia ki ngā kākahu whenua.
- Ngā Kaupapa Taupoki:
  - Ko ngā parepare wai te nuinga o te wā e whakamahia ana mō te whakahaere waipuke, ā, ko te arotahi o ā rātou whatunga waikeri he tango i te wai e turuturu ana mai i te tinana o te parepare me te turanga. Ka whakatūria ngā paipa waikeri ki roto i te tinana o te parepare, ā, ka whakatūria ngā pakitara tapahi me ngā puna waikeri ki te wāhanga turanga. Ka taea e te pakitara tapahi te ārai i ngā wai o waho pērā i te wai awa kei uru ki roto i te turanga, ā, ka taea e ngā puna waikeri te tango i te wai e turuturu ana i roto i te turanga, te whakaheke i te taumata wai whenua o te turanga, me te ārai i ngā āhuatanga kino pea pērā i te pupuhi o ngā paipa ki roto i te turanga.
- Ngā Kaupapa Rāhui:
  - Ehara i te mea ko te rerenga wai o te tāhuna anake te mea e hiahiatia ana kia whakaarohia e te whatunga rerenga wai o te puna wai, engari ko te rerenga wai o ngā maunga e karapoti ana. Ka whakatūria he awaawa ārai ki ngā pari e karapoti ana i te puna wai hei ārai i te rerenga wai o te mata o te puna wai pērā i te wai ua, ā, ka tukuna atu ki ngā awa rerenga wai i waho o te puna wai, kia kore ai e horoia ngā pari e te wai ua, e uru atu rānei ki roto i te turanga o te tāhuna puna wai. I taua wā anō, me whakarite e ngā whakaurunga rerenga wai o te tāhuna puna wai kia taea te whakaheke i te wai e mimiti ana mai i te tinana o te tāhuna i te wā tika kia pai ai te haumaru o te tāhuna.
