I te awheawhe o Jinbin, kei te tukatuka ngā kaimahi i ētahi kowiri tirangā kūaha penstockHe tino pai te keti penstock e piri ana ki te pakitara he kowiri tira te tae i roto i ngā mara o te tiaki wai me te tuku wai me te rerenga wai. Ko te take matua kei roto i ōna painga ā-roto i roto i ngā āhuatanga maha pēnei i te rauemi, te hanganga, me te tono. Ka tautokohia e ēnei painga tetahi ki tetahi, ka hanga he whakataetae whānui e nui atu ana i ngā keti tuku iho. (Ngā Kaihanga Penstock)

Ko ngā āhuatanga o te rauemi te pūtake matua o tōna whakatūnga. He mea hanga te tinana matua ki te maitai kore waikura 304, 316 rānei, ehara i te mea he tino kaha te ātete ki ngā waikawa, ki ngā kawakore me te waikura anake, ā, ka taea hoki te ātete ki te horo o ngā momo waikura, engari ka taea hoki te urutau ki te rumaki roa i roto i ngā taiao makuku me te wai nui, ka karo i ngā raruraru o te waikura ngāwari me te tawhito o ngā kēti whakarewa tuku iho, ā, ka whakarite i te pumau o te hanganga me te haumaru o te whakamahinga o te kēti mai i te pūtake.

He nui ngā painga o te hanganga motuhake e mau ana ki te pakitara. Kāore he take ki te ringihia he turanga poupou taumaha. Ka taea te tāpiri tika ki te pakitara, ki te pakitara puna kaukau rānei mō te tāutanga pumau, ka whakangawari ake i te tukanga hanga ā-iwi, ka whakaiti hoki i te utu katoa o te kaupapa. Ka taea e tōna hoahoa rahinga kiato te urutau ngāwari ki ngā āhuatanga iti te wāhi pērā i ngā whatunga paipa tawhito me ngā rūma papu whaiti, ka whakaoti pai i te raruraru o te nui o te wāhi tāutanga mō ngā kēti waipara tuku iho.

He whānuitia ngā āhuatanga e tika ana, ā, he kaha hoki tōna urutau. Ahakoa ko te pūnaha tuku wai tuarua o ngā whare ā-iwi, ko ngā awa whakamakuku o te mahi ahuwhenua, ko ngā whatunga rerenga wai me ngā whare maimoatanga paru i roto i te ao ahumahi rānei, ka taea e rātou katoa te whakatutuki i ngā tono me ā rātou mahi whakatuwhera me te kati pumau me ngā āheinga whakahaere ngāwari, ā, kāore e herea e te whānuitanga pāmahana me te pēhanga reo noa.

Ko te ngāwari o te tiaki me te roa o te mau, he painga ōhanga rua. He maeneene, he matotoru te mata o te kowiri tira, ā, he uaua ki te piri te paru me ngā mea poke. Ko te tiaki o ia rā me horoi noa iho, ā, kāore e hiahiatia kia tangohia te waikura, kia peitahia rānei. He tino iti te utu tiaki ā-tau. I taua wā anō, he kaha te hanganga o te takirere penstock kowiri tira, he kaha te ātete ki te kakahu, ā, he roa ake te ora ratonga i ērā o ngā kēti tuku iho, ka whakaiti i te auau o te whakakapinga me te haumitanga i muri mai.
