I roto i te awheawhe o Jinbin, he kowiri tira 2-mita te roatakirere kuaha penstock kua mau ki te hongereKei te tāutahia te taputapu hiko me te whakatikatika i ngā hapa e te kiritaki, ā, kei te tirotirohia e ngā kaimahi te whakatuwheratanga me te katinga o te pereti kēti. Ko te kēti penstock hongere maitai kore waikura 2-mita te roa (ko te rauemi matua he maitai kore waikura 304/316L) he taputapu whakahaere matua i hangaia mō ngā āhuatanga kawe wai hongere rere nui. Nā ōna āhuatanga rauemi me te arotautanga hanganga, he tūranga nui tōna i roto i ngā mara pēnei i te tiaki wai, ngā mahi ā-tāone, me te ahumahi.

Ko ōna āhuatanga matua e arohia ana ki ngā āhuatanga e toru: te hanganga, te hiri me te whakahaere: Ka whakamahia he pereti kuaha kua oti te hanga me te anga tatau, he kiato, he tino pakari, e tika ana mō ngā whakaritenga whakahaere rere o ngā awaawa 2-mita te whānui, ā, kāore he hoahoa tauhou. Ka whakamahia e te pūnaha hiri he hiri ngohengohe rapa, he hiri mārō whakarewa rānei, me ngā tikanga tukatuka tika, kia pai ai te taunga i waenga i te pereti kuaha me te anga tatau, kia tutuki ai he pānga hiri kore-takiri. Ka tautokohia e te aratau whakahaere ngā hiki ā-ringa me ngā hiki hiko (me te waeine mana mamao whiriwhiri), ka urutau ki te whakahaere watea i raro i ngā āhuatanga mahi rerekē. He tere te tere urupare o te tauira hiko, he iti te utu tiaki o te tauira ā-ringa.

He tino kaha te ātete o te takirere penstock kowiri tira ki te waikura me te ātete ki te kakahu. Ka taea e ia te ātete ki te horo o ngā mea matatini pēnei i te paru waikawa me te kawakore me te rere o te wai onepu. Ko tōna roanga mahi he 3 ki te 5 ngā wā i te takirere kuaha maitai waro noa. Ko te diameter nui e tutuki ana i te hiahia mō te tuku wai rere-rahi, me te whakawhiti whakawhiti maeneene me te iti o te ngaronga waipēhi, e whakarite ana i te pai o te tuku wai o te awaawa. Ka whakaarohia e te hoahoa hanganga te tāutanga me te tiaki. He mama, he ngāwari ki te wetewete me te huihui. Ka taea te whakaoti i te tiaki me te kore he taputapu uaua, ka whakaiti i ngā utu whakahaere me te tiaki. He pai te mahi tiaki taiao. He mea hanga ki te kowiri tira, kāore e puta he parahanga tuarua, ā, e tutuki ana i ngā paerewa tiaki taiao mō te wai inu me te maimoatanga paru. Heoi anō, he pumau te ātete pāmahana teitei me te iti, ā, he pai mō ngā āhuatanga mahi tino kino mai i te -20 ℃ ki te 80℃.

Ka hipokina e ngā horopaki tono ngā āhuatanga mahi matua o ngā ahumahi maha: I roto i ngā kaupapa tiaki wai, ka whakamahia mō te whakahaere taumata wai me te whakahaere rere i roto i te whakahaere awa, ngā awa turuturu o ngā puna wai, me ngā awa whakamakuku whenua ahuwhenua, he mea tino pai mō ngā awa matua o ngā rohe whakamakuku nui me ngā kaupapa whakawhiti wai ā-rohe. I roto i te mara o te tuku wai me te rerenga wai ā-tāone, ka whakamahia whānuitia i roto i ngā awa whakauru me te rerenga wai o ngā tipu maimoatanga parakaingaki, te aukati i ngā whatunga wai ua, me ngā awa kawe wai mata o ngā mahi wai, ā, ka taea te whakahaere tika i te pana rere wai me te tere rere. I roto i te mara ahumahi, ka taea te whakamahi mō ngā awa wai e rere ana me ngā awa maimoatanga wai parakaingaki i roto i ngā ahumahi matū, hiko me te whakarewa, e ātete ana i te waikura o te wai parakaingaki ahumahi me te whakarite i te pumau o te tuku wai whakaputa.
