Ina pakaru ngā paipa wai o raro i te whenua, tata tonu te take kotahi: te waikura. Mō ngā tekau tau, kua whawhai ngā miihini me ngā kaiwhakahaere kaupapa ki tēnei pakanga me ngā paninga e pakaru ana, ngā arai e tihore ana, me ngā whakatikatika e kore e roa.
Engari he ara mātau ake inaianei.
TePaipa Raina Polypropylene Kei te whakarerekē te kamupene Cangzhou Spiral Steel Pipes Group Co., Ltd. i te pūnaha wai o raro whenua. Engari ko te peita noa i tētahi paparanga tiaki, kei roto i tēnei paipa he arai polypropylene e piri ana ki te maitai. Whakaarohia he parenga kua hangaia ki roto, e kore e taea e ngā mea waikura te uru atu.
Nā, me pēhea te aukati i te waikura?
He māmā noa iho. Ka hangaia e te arai polypropylene he ārai katoa i waenganui i te maitai me ngā mea katoa e rere ana i roto—e karapoti ana rānei—i te paipa. Ko te wai, ko ngā matū, ko ngā waikawa oneone… kāore tetahi o ēnei e pā ki te maitai. I taua wā, ko te paipa maitai tonu he mea hanga mā te whakamahi i te hangarau whakarewa pewa hurihuri matatau, ko te tikanga he iti ake ngā wāhi ngoikore me te roa ake o te ora ratonga.
E mōhio ana te hunga o Cangzhou Spiral Steel Pipes Group ki te hanga paipa roa. I whakatūria i te tau 1993, kua tipu rātou hei tētahi o ngā kaihanga matua o Haina i tēnei ao. Ko te rahi o tā rātou mira i Cangzhou City he 350,000 mita pūrua, ā, e 680 ngā kaimahi e whakahaere pai ana i ngā mahi. I ia tau, e 400,000 tana o ngā paipa maitai porowhita e hangaia ana e rātou—ko te uara whakaputa he tata ki te 1.8 piriona Yuan.
He aha te tikanga o tēnā ki a koe? Ko te tikanga ehara tēnei i te hua whakamātautau mai i tētahi kamupene hou. Kua whakamatautauria ēnei paipa i te mara, kua hangaia kia nui, ā, kua hangaia hei whakahaere i ngā kaupapa tuku wai whenua o te ao tūturu.
Mō ngā pūnaha paipa wai o raro whenua, ehara i te mea he kōwhiringa kia pakaru. Kia uru te paipa ki te whenua, he nui te utu mō te keri anō. Mā te paipa polypropylene ka taea e koe te tāuta kotahi, ā, ka warewarehia mō ngā tekau tau.
Ā, he pono? Koinei te momo rangimarie o te hinengaro he uaua ki te whakatakoto utu.
