Pereti Waikeri Kirihou, he mea hanga mai i tētahi papa matua kirihou kua whakapūwerohia me tētahi geotextile kore-whatu kua takaihia ki ōna taha e rua. Ko te pereti matua te angaanga me te awaawa o te whitiki waikeri, ā, he rite te āhua o tōna whakawhiti ki te whakawhiti, ka taea te ārahi i te rere o te wai. Ka taea e te geotextile i ngā taha e rua te mahi tātari hei ārai i ngā matūriki oneone kei aukati i te awaawa waikeri.
1, Ko te kaupapa mahi o te papa waikeri kirihou e ahu mai ana i tōna hoahoa awaawa waikeri poutū ahurei. I roto i te maimoatanga turanga oneone ngohengohe, ka whakauruhia poutū te papa waikeri kirihou ki roto i te papa oneone ngohengohe mā te mīhini whakauru papa, ka taea te hanga i tētahi raupapa awaawa waikeri tonu. Ka honoa ēnei awaawa ki te papa onepu moenga o runga, ki ngā paipa waikeri kirihou whakapae rānei, hei hanga i tētahi pūnaha waikeri katoa. Ina tukuna te kawenga utaina ki te wāhanga o runga, ka tukuna te wai kore i roto i te turanga oneone ngohengohe ki roto i te papa onepu, i te paipa waikeri whakapae rānei kua whakatakotoria ki te wāhanga o runga mā te awaawa o te papa waikeri kirihou i raro i te mahi a te pēhanga, ā, ka tukuna atu i ētahi atu wāhi. Ka tere ake te whakapūmautanga o te turanga ngohengohe e tēnei tukanga, ā, ka whakapai ake i te kaha kawe me te pumau o te turanga.
2, He tino pai te tātari wai o te papa waikeri kirihou, he maeneene hoki te waikeri, ā, he tino kaha, he ngāwari hoki, ā, ka taea te urutau ki te āhua rerekē o te turanga me te kore e pā ki te mahi waikeri. Heoi anō, he iti te rahi whakawhiti o te papa waikeri, ā, he iti te whakararuraru ki te turanga, nō reira ka taea te hanga papa whakauru i runga i te turanga tino ngohengohe. Nō reira, he tino pai hoki te pānga waikeri i raro i ngā āhuatanga whenua uaua.
3, I roto i te hangarau, ka pāngia te pānga mahi o te papa waikeri kirihou e te maha o ngā āhuatanga.
（1）Me whakarite te hohonutanga me te tawhiti o ngā papa waikeri kia rite ki ngā āhuatanga o te turanga me ngā whakaritenga hoahoa. Mēnā he papaku rawa te hohonutanga o te whakaurunga, he nui rawa rānei te tawhiti, ka kore e pai te waikeri.
（2）He mea nui anō hoki te whakatakoto i te paparanga onepu o runga, i te paipa waikeri whakapae rānei. He tino pai te uruhanga wai me te pumau hei whakarite i te mahi pai o te pūnaha waikeri.
（3）Ko te whakahaere kounga i te wā hanga he mea nui anō hoki e pā ana ki te pānga o te rerenga wai. Tae atu ki te teitei o te tāutanga, te tere o te tāutanga, te roa o te hokinga mai, me ētahi atu mea o te papa rerenga wai, me tino whakahaere katoa kia mau tonu ai te pai o te papa rerenga wai me te rere maeneene o te awa rerenga wai.
Heoi, ko te mātāpono mahi o te papa waikeri kirihou e pā ana hoki ki te whiriwhiri i tōna rauemi. Ko te papa matua he mea hanga i te polypropylene (PP) me te polyethylene (PE). He pakari rite tonu ki te polypropylene me te ngāwari me te ātete ki te huarere rite tonu ki te polyethylene. Nō reira, ehara i te mea he kaha te papa waikeri anake, engari ka taea hoki te pupuri i te mahi pumau i raro i ngā āhuatanga taiao kino. I te wā e whiriwhiri ana i te geotextile, me whakaaro hoki ki tōna mahi tātari me te pakari kia pai ai te rere o te awa waikeri mō te wā roa.
