Whakaahuatanga Poto:

Ko te umanga tae kakahu tētahi o ngā pūtake matua o te parahanga o ngā waipara ahumahi o te ao. Ko te waipara tae he ranunga o ngā rauemi me ngā matū e whakamahia ana i roto i ngā tikanga tā me te tae. He maha ngā wā kei roto i te wai he nui ngā kukū o ngā matū koiora me te rerekētanga pH nui, ā, he rerekētanga nui te rere me te kounga o te wai. Nō reira, he uaua ki te whakahaere i tēnei momo waipara ahumahi. Ka kino haere te taiao mēnā kāore e tukatukahia tika.

Ka taea e tētahi mira kakahu rongonui i Guangzhou te tuku i te kaha tukatuka paru tae atu ki te 35,000m3 ia rā. Mā te whakamahi i te tikanga whakapūngao whakapā, ka taea te whakaputa paru nui engari he iti te ihirangi totoka. Nō reira, me whakatōtō mua i mua i te tukanga whakamaroke. I hokona e tēnei kamupene e toru ngā mīhini tātari whitiki whakamaroke-whakamaroke hurihuri raupapa HTB-2500 mai i tā mātou kamupene i te Paenga-whāwhā, 2010. Kua pai te mahi a ā mātou taputapu tae noa ki tēnei wā, ā, kua whiwhi mihi nui mai i ngā kiritaki. Kua tūtohutia hoki ki ētahi atu kiritaki i roto i te umanga kotahi.
