I ngā tāone takutai me ngā wāhi haumākū nui, he hononga tika te roa o te pūnaha waikeri ki te haumaru me te whakahaere me te tiaki i ngā hanganga tāone. Ko ngā tāone takutai noa pērā i a Hong Kong me Singapore ka pāngia e te waikura i te hau tote nui me te āhuarangi haumākū i te tau katoa. Ko ngā paipa waikeri rino tuku iho he ngāwari ki te turuturu me te pakaru nā te waikura, ā, ka puta he parahanga taiao me ngā tūponotanga huna i roto i ngā hanganga whare. Hei whakautu i tēnei raruraru,DINSENkua whakarewahia e mātou tētahi hua hou – arā, ngā paipa waikeri rino maka kua rehuhia ki te konutea, e whakahou ana i ngā otinga ahumahi mā roto i ngā tukanga auaha me te mahi paerewa teitei.
He nui ake te waikura o ngā paipa whakarewa i te taiao takutai moana i ngā rohe o uta. Ka honoa ngā katote kōhaita i roto i te rehu tote ki te makuku o te rangi hei whakatere i te waikura whakarewa, ka tere te taka o te paparanga konutea i runga i te mata o ngā paipa whakarewa tuku iho, ā, ka mutu ka waikura te tinana o te paipa. Hei tāpiri, ka nui ake te tawhito o te paninga nā te huringa auau o te pāmahana me te hihi ultraviolet. He uaua ki te pupuri i ngā pānga tiaki roa mō ngā hangarau ārai-waikura tuku iho (pēnei i te whakarewa noa, te peita rānei) i roto i ngā āhuarangi uaua. Ko te whakakapinga auau o ngā paipa ehara i te mea ka piki ake ngā utu anake, engari ka pāngia hoki te mahi noa o te tāone.
Ko te wā ārai-waikura o te konutea i rehuhia ki te wera e 4-10 ngā wā teitei ake i tō te maitai kāore i rongoatia.Ko te rerekētanga motuhake e whakawhirinaki ana ki te taumata taiao me ngā paerewa tukanga. I raro i ngā tikanga hanga paerewa, ka taea e te konutea rehu-wera te whakarato i te tiaki roa mō te neke atu i te 20 tau, ko te maitai kāore i rongoatia ka roa pea mō te 3-5 tau i raro i te taiao kotahi. Ko te ahua e whai ake nei he whakataurite tika i waenga i ngā paipa rino maka kua rehuhia ki te konutea me ngā mea kāore i rehuhia ki te konutea. Ko te taha maui he paipa rino maka kua rehuhia ki te konutea (DN50 EN877:2021 A1 Z), ā, ko te taha matau he paipa rino maka noa.
Kua paahitia e te mahi ārai-waikura o tēnei tukanga ngā whakamātautau pakari o te paerewa EN877 (tae atu kiwhakamātautau rehu tote, whakamātautau waikura hurihuri, me ētahi atu).Ko te EN877 te paerewa tiwhikete mana mō ngā paipa waikeri rino maka i Ūropi, e whakatakoto ana i ngā whakaritenga pūnaha mō ngā āhuatanga miihini, te hiri me te kaha ārai-waikura o ngā paipa.He pai ngā paipa rino maka a DINSEN kua rehuhia ki te konutea mō ngā whare teitei, ngā ara paipa whakauru kei raro i te whenua me ētahi atu wāhi e uaua ai te hanga pinepine.E tutuki katoa ana i a rātou te paerewa EN877, ā, e rongonui ana i waenga i ngā kaihoko teitei nā ō rātou painga ārai-waikura.
I tēnei wā, kua angitu te whakamahinga o te hua i roto i ngā whare rongonui maha o Hong Kong (pērā i ngā whare arumoni me ngā kaupapa whakawhānui taunga rererangi), ā, kua āta whakatairangahia ki ngā rohe takutai moana pērā i te Tonga-mā-rāwhiti o Āhia me te Waenganui Rawhiti. Ehara i te mea ko tōna uara anake e whakaatahia ana i roto i tana mahi hangarau, engari anō hoki.e whiwhi ana i te manako o ngā kiritaki nā te painga utu katoa o te huringa ora – ahakoa he paku teitei ake te haumitanga tuatahi i tērā o ngā paipa noa, ka taea e ōna āhuatanga kore tiaki mō te wā roa te whakaiti i te utu katoa mā te neke atu i te 30%.
I raro i ngā pēhanga takirua o te noho tāone me te huringa āhuarangi, me whakapai ake te "rārangi parepare ngaro" o ngā hanganga. Mā te hangarau hou ārai-waikura me te tiwhikete paerewa teitei, ka whakaratohia e ngā paipa rino maka DINSEN kua rehuhia ki te konutea he otinga rerenga wai pono me te pumau ki ngā tāone takutai. I te heke mai, i te mea ka piki haere te hiahia o te ao mō ngā tāone pakari, ka taea e tēnei hangarau te tautuhi anō i te paearu ahumahi me te whakatairanga i te whakawhiti o ngā paipa rino maka mai i ngā "wāhanga mahi" ki ngā "wāhanga uara".
