Ko te keri taiao he huarahi hangarau matua hei tango me te rongoā i ngā paru wai poke. Ko tōna whāinga matua he whakaoti pai i te mahi keri me te whakaiti i ngā raruraru taiao (pēnei i te whakapūtanga anō o te paru, te horapa o ngā parahanga, me ētahi atu). E ai ki ngā rangahau a te Western Dredging Association (WEDA), ko te uauatanga o te keri taiao kei roto i te whakataurite i ngā whāinga "5R" (tango, whakapūtanga anō, tuku, toenga).pērā anō, me te mōrearea).
Ngā ngongo keri CDSRHe mea nui te mahi a ngā paipa keri hei whakarite kia tere te tango i ngā paru o raro. Ko te tukanga keri me kawe te paru, te onepu me ētahi atu rauemi ki ngā wāhi maimoatanga kua tohua, ki ngā wāhi tukunga rānei mā roto i ngā paipa. He nui ngā tono a tēnei tukanga mō te ātete ki te kakahu me te kaha ā-pūkaha o ngā paipa. He mea hanga te ngongo keri CDSR ki ngā rauemi kaha-teitei, ka taea te ātete pai ki te pakū o ngā rauemi kukū-teitei mō te wā roa, ā, ka whakarite kia haere tonu me te pumau ngā mahi keri.
Ko te hiahia kia whakaitihia te whakapūtanga o te paru i te wā e keri ana i te taiao, me whai whakaaro ki ngā āhuatanga wai i te wā e hoahoa ana i ngā ngongo keri. Ka whakaitihia e te ngongo keri CDSR te pōrearea wai i te wā e kawe ana mā te arotau i te maeneene o te pakitara o roto me te taurite o te diameter o te paipa, ā, ka whakaitihia te āhuatanga whakapūtanga o te paru i puta mai i ngā rerekētanga o te tere rere. Ehara i te mea ka whakatairanga noa i te kawe maeneene o ngā paru, engari ka aukati hoki i te horapa o ngā poke ki tētahi taumata, ka āwhina ki te whakahaere i ngā mōrearea.
He maha ngā momo poke e mau ana i ngā paru e uru ana ki te keri wai taiao. Me pai te pumau o te matū o te ngongo kia kore ai e pāngia te wai e ngā wāhanga o te wai. Ka whakamahia e te ngongo keri wai CDSR ngā rauemi hiato e pai ana ki te taiao, ā, e ātete ana ki te waikura, kia pai ai te mahi i raro i ngā āhuatanga mahi uaua, kia whakaitihia ai te tūponotanga o te dialysis poke, me te whakatairanga i te haere tonu o ngā mahi keri wai taiao.
Mō te whakahaere toenga, ko te hoahoa o te ngongo keri e aro ana ki te hiri me te pumau o ngā hononga hei ārai i te turuturu i te wā e kawe ana. Ko ngā ngongo keri CDSR e whakamahi ana i ngā hononga flange. Ina koa i raro i ngā āhuatanga pēhanga teitei, ka taea e ngā hononga flange te whakarato i te mahi pono, te whakaiti i ngā mōrearea taiao e puta mai ana i te rahunga o ngā taputapu, me te whakatutuki i ngā whakaritenga ture taiao tino pakari.
He tino ngāwari hoki te urutau o te ngongo keri CDSR ki ngā momo mahi keri me ngā āhuatanga taiao. Ka whiriwhiria e ā mātou tohunga hangarau te huinga rauemi me te hanganga tino tika i runga i ngā whakaritenga motuhake a ngā kiritaki mō te taumata pēhanga, te ātete kakahu, te kaha piko, me ētahi atu. Mā te hoahoa ritenga, ka taea e te ngongo keri CDSR te aro atu ki ngā momo āhuatanga mahi uaua pēnei i te keri moana, te keri awa, te tango paru i te tauranga, me ētahi atu, kia pai ai te mahi keri, kia iti ai hoki te pānga ki te taiao.
Nā te whakamahinga o te ngongo keri CDSR kua tino whakapai ake i te taumata haumaru, whai huatanga me te tiaki taiao o ngā mahi keri taiao. Ko ōna āhuatanga ā-tinana me te pumau matū pai rawa atu ehara i te mea ka āwhina i te keri taiao ki te whakatutuki i ngā whakaritenga o te whāinga "5R", engari ka whakarite hoki i te tango pai o ngā paru me te whakahaere i te parahanga.
