Ngā Wāhanga E manawapa ana:E toru ngā wāhanga o te whakatārewatanga o te motuka: te wāhanga rapa, te ngongo ru me te taputapu tuku kaha, e mahi ana i ngā mahi hei whakangāwari, hei whakaiti me te tuku kaha.
Puna koiri:Koinei te puna e whakamahia nuitia ana i roto i ngā motuka hou. He kaha tōna kaha ki te mimiti i te ru, ā, he pai te whakamarie o te ekenga; ko te ngoikoretanga he roa, he nui te wāhi e nohoia ana, ā, he nui hoki te mata pa o te tūranga tāutanga, e uaua ai te whakatakotoranga o te pūnaha whakatārewatanga kia tino kiato. Nā te mea kāore e taea e te puna koiri te tu atu i te kaha taha, me whakamahi te tikanga whakakotahi matatini pēnei i te puna koiri pae-whā i roto i te whakatārewatanga motuhake. Hei whakaaro ki te whakamarie o te ekenga, e tumanakohia ana ka ngawari ake te puna mō te pānga whenua me te auau teitei me te kaha iti, ā, ina nui te kaha pānga, ka taea e ia te whakaatu i te pakari nui ake me te whakaiti i te whiu pānga. Nō reira, me rua, neke atu rānei ngā pakari o te puna i te wā kotahi. Ka taea te whakamahi i ngā puna he rerekē ngā diameter waea, he rerekē rānei te teitei, ā, ka piki ake tō rātou pakari i te pikinga o te kawenga.
Puna rau:Ko te nuinga o te wā e whakamahia ana mō ngā waka me ngā taraka. He maha ngā rau puna angiangi e hangaia ana, he rerekē te roa. Ki te whakatauritea ki te puna koiri, he iti ngā painga o te tauira whaipainga, he māmā te hanganga, he iti hoki te utu, ka taea te whakakotahi kiato ki raro i te tinana o te waka, ā, ka puta he waku i waenga i ngā pereti i te wā e whakamahia ana, nō reira he pānga whakaiti. Heoi, ki te nui te waku maroke, ka pā ki te kaha ki te mimiti i te pānga. Kāore i te maha ngā wā e whakamahia ana ngā waka hou e aro nui ana ki te whakamarie o te eke.
Puna pae hurihuri:He pae roa tēnei i hangaia ki te maitai puna, he pakari hoki tōna ātete ki te takahurihuri. Ka herea tetahi pito ki te tinana o te waka, ā, ka honoa tetahi pito ki te ringa o runga o te whakatārewatanga. Ina neke te wira ki runga, ki raro hoki, ka takahurihia te pae takahurihuri, ka whakapōturitia kia mahi hei puna.
Puna hau:Whakamahia te āheinga pēhi o te hau hei whakakapi i te puna whakarewa. Ko tōna painga nui ko tōna pakari rerekē, ka piki haere mārire me te pēhi tonu o te hau, ā, he tukanga haere tonu tēnei pikinga, he rerekē ki te huringa whakarōpū o te puna whakarewa. Ko tētahi atu painga ko tōna āheinga whakarerekē, arā, ka taea te whakarerekē kaha i te pakari o te puna me te teitei o te tinana o te waka.
Mā te whakamahi ngātahi i ngā rūma hau matua me ngā rūma hau āwhina, ka taea e te puna te noho i roto i te āhua mahi o ngā pakari e rua: ina whakamahia ngā rūma hau matua me ngā rūma hau āwhina i te wā kotahi, ka nui ake te kaha hau, ka iti ake te pakari; engari (ko te rūma hau matua anake ka whakamahia), ka nui ake te pakari. Ka whakahaerehia te pakari o te puna hau e te rorohiko, ā, ka whakatikatikaina kia rite ki te pakari e hiahiatia ana i raro i ngā āhuatanga o te tere teitei, te tere iti, te aukati, te whakatere me te huri. He ngoikore anō hoki te puna hau, me whakauru he papu hau ki te teitei o te waka whakahaere huringa pēhanga, me ngā taputapu whakahaere maha, pērā i te whakamaroke hau. Ki te kore e tiakina tika, ka puta he waikura me te pakaru o te pūnaha. Hei tāpiri, ki te kore e whakamahia ngā puna whakarewa i te wā kotahi, kāore e taea e te motuka te oma mēnā ka turuturu te hau.
