He mea nui te whakapai ake i te whai huatanga me te kounga i roto i te umanga hanga taumaha e whanake tonu ana. Ko tētahi o ngā whanaketanga nui o te hangarau whakarewa kua puta ake i ngā tau tata nei ko te whakarewa pewa rua-uru (DSAW). Ehara i te mea ka whakarei ake tēnei hangarau auaha i te hanganga o ngā wāhanga whakarewa anake, engari ka whakangawari ake hoki i te tukanga hanga, ka waiho hei huringa nui mō ngā umanga e whakawhirinaki ana ki ngā rauemi taumaha.
Kei te ngako o te DSAW tōna kaha ki te whakaputa i ngā whakarewa kounga teitei me te iti o ngā hapa. Kei roto i te tikanga e rua ngā pewa e tanumia ana i raro i tētahi paparanga o te rere o te kirikiri, e tiaki ana i te puna whakarewa mai i te poke me te waikura. Ko te hua he whakarewa ma, kaha ake e taea ai te tu atu i ngā uauatanga o ngā tono hanga taumaha. He mea nui tēnei mō ngā kamupene e whakaputa anahanganga whakarewa mataongā wāhanga tuwhera, pērā i ngā mea kua tohua i roto i ngā paerewa Pākehā he porowhita, he tapawhā, he tapawhā rānei te āhua. He mea nui ēnei wāhanga i roto i ngā momo mahi, tae atu ki te hanga, te hanganga me ngā mīhini taumaha.
Kei Cangzhou, Porowini o Hebei, e whakaatu ana te wheketere i ngā painga o te DSAW i roto i te hanga taumaha. I whakatūria i te tau 1993, e 350,000 mita pūrua te rahi o te tipu, ā, e 680 miriona yuan te tapeke o ngā rawa. Me te 680 ngā kaimahi pono, ko te wheketere te kaiārahi i roto i te hanga i ngā wāhanga hanganga tuwhera kounga teitei. Mā te whakauru i te DSAW ki roto i te tukanga hanga, kua tino whakapai ake te wheketere i te pai o te mahi me te kounga o te hua.
Ko tētahi o ngā painga matua o te DSAW ko te tere. Mā te tukanga ka taea te tere ake i ngā tere whakarewa i ngā tikanga tuku iho, ka whakaiti i te wā whakaputa. He mea nui tēnei whai huatanga mō ngā mahi hanga taumaha e hiahiatia ana te wā. Mā te whakaiti i te wā whakarewa, ka taea e ngā kaihanga te whakanui ake i te whakaputanga me te whakatutuki i ngā hiahia o te mākete whakataetae.
Hei tāpiritanga, kei te teitei tonu te kounga o te whakarewa DSAW. Mā te tukanga pewa ruku ka whakaitihia te mōrearea o ngā hapa pēnei i te porosity me ngā whakaurunga ka taea te whakararu i te hanganga o te hua whakamutunga. He mea nui tēnei mō ngā wāhanga hanganga tuwhera kua whakarewahia i hangaia i te makariri, me tutuki i ngā paerewa kounga pakari hei whakarite i te haumaru me te pono o ā rātou tono. Ka whakamahia e te wheketere o Cangzhou tēnei hangarau hei whakarite kia tutuki i āna hua ngā paerewa ahumahi, engari kia eke ki runga ake i aua paerewa.
Haunga te whakapai ake i te whai huatanga me te kounga, ka āwhina hoki a DSAW ki te penapena utu. Mā te iti o ngā hapa, ka iti ake te hiahia ki te mahi anō, ko te tikanga ka taea e ngā kaihanga te tohatoha rauemi me te whai hua ake. He tino whai hua tēnei mō te whakaputanga nui, ina he mea nui ngā utu rauemi me te mahi ki ngā whakapaunga whakaputa katoa.
I te tipu haere tonu o te umanga hanga taumaha, ko te whakaurunga o ngā hangarau whakarewa matatau pēnei i tepewa ruku rua i whakarewainaka whai wāhi nui ki te hanga i te heke mai. Ko ngā kamupene e haumi ana ki tēnei hangarau, ehara i te mea ka whakapai ake i te whai huatanga o te mahi engari ka whakarei ake hoki i te kounga o te hua, ā, ka whiwhi i tētahi tūranga ārahi i roto i tētahi mākete whakataetae nui.
I roto i te poto, ko te whakarewa pewa rua-rua kei te huri i te hanga taumaha mā te whakapai ake i te whai huatanga me te kounga. Ko tēnei wheketere i te Tāone o Cangzhou he tauira pai o te huarahi e taea ai te whakauru pai i te hangarau ki roto i te tukanga whakaputa, e whakaputa ana i ngā wāhanga hanganga tuwhera kounga teitei e tutuki ai ngā hiahia o te ahumahi hou. I a ngā kaihanga e whai ana kia hiranga, ko te whakamahi i ngā hangarau auaha pēnei i te DSAW he mea nui ki te angitu i ngā tau e haere ake nei.
