Ko te hanganga whakarewa e arotahi ana ki ētahi hononga pēnei i te whakarewa titi, te peita bitumen, te whakaranu wai, te whakapiri pokepokea ai, te wiri, te tiaki tuku pokepokea ai, te whakapumautanga rahi, me te tika o ngā pūwāhi ine, ā, ka mahia te whakatinanatanga i runga anō i ngā whakaritenga a te kaihanga rauemi me te wheketere poiha.
1. Tāutanga whao pine me te hopu
I mua i te pēhanga wai, me whakakī ngā pine i ngā wāhi e tika ana pērā i ngā hononga whakarewa o te mata whakamahana me ngā hononga whakarewa whakakotahi me ngā hononga o te mata whakamahana i te wā e kawe ana me te tāuta ana. Whakatikahia te whakarewa me te hopu i ngā whao kia tika ai te whakarite o ngā pine kia rite ki te matotoru kua hoahoatia. I mua i te ringihanga, pania he paparanga peita uku he matotoru ake i te 1mm ki ngā wāhanga whakarewa katoa kua whakauruhia, ngā whao me ētahi atu mata whakarewa, takai rānei i ngā rauemi mura.
2. Ngā Kai, te tohatoha wai, te whakahaere whakaranu
Ka paunatia ngā kai, ka tohatohahia te wai kia rite ki ngā whakaritenga o te pukapuka ā-ringa rauemi a te kaihanga rauemi, ā, ko te tangata kua tohua te kawenga mō te ine tika. Ko te wai e whakamahia ana mō te whakaranu i ngā mea whakarewa me waiho hei wai ma (pērā i te wai inu), me te pH o te 6~8. Kia tūpato ki te raupapa o te tāpiri wai me te wā whakaranu me te whakaranu. Kāore e whakaaetia te tāpiri wai i te hiahia, ā, kāore e whakaaetia te whakanui ake, te whakaroa rānei i te wā whakaranu i te wā noa. Kaua te nui o te wai e tāpirihia ki te wāhi kotahi, ā, me whakaranu katoa te mea whakarewa. Me tāpiri te muka maitai ki te mea whakarewa i te wā e tāpirihia ana te wai me te whakaranu, ā, kaua e whakaranua ki roto i ngā mea whakaranu.
3. Mana whakahaere tauira
He tukanga tino nui te hanga pokepokea ai, ā, ko te kounga o te pereti pokepokea ai e pā tika ana ki te kounga o te mea e taea te whakarewa. Ko te whakahaere tauira e aro ana ki te whakaae ki tōna pakari me te tika o ngā āhuatanga. Me pakari te tauira, ā, me huihui pūmau kia kore ai e nekeneke, e wetekina rānei i te wā e ringihia ana. Me whakatakoto te pokepokea ai rakau kia rite ki ngā āhuatanga āhuahanga o te tuhi hanga me te matotoru o te ringihanga, kua oti te hanga me te huihui, ā, me pūmau te atanga. He tauira 15 cm te roa o te pokepokea ai me te tapawhā rakau, he whānui ≤500mm; he tapawhā rakau te pokepokea ai āhua motuhake, ā, kua hipokina ki te papa paparanga e toru henimita te roa, ka paraihehia te mata ki ngā mea tuku e rua kia pai ai te matotoru o te mea e taea te whakarewa me te mata i muri i te hanganga kia maeneene, kia ma, kia kore he poka. Me tirotiro me te whakaae te hanganga o te pokepokea ai i mua i te hanganga.
4. Mana ringihanga
I te ringihanga o te mea whakarewa, ka whakahaerehia te teitei o ia whāngai i te awhe o te 200~300mm, ko te wāhanga he nui ake te matotoru i te 50mm ka ringihia ki te wiri wiri e whakaurua ana, ā, ka whakamahia te tikanga "tere ki roto, puhoi ki waho" hei wiri tonu i te wā e wiri ana hei ārai i te pupuri. Mō te wiri o te kōhao o raro me te turuturu, kaua e roa rawa te wā wiri o ia pūwāhi kia kore ai e rere te paura pai. I te wā e wiri ana, kaua te tokotoko wiri e pā ki te tauira, kaua hoki e mau rawa ngā whao. I te ringihanga o ngā mea whakarewa he nui ake i te 50mm te matotoru, me hanga te wāhi nui ake i te 10m2 ki ngā pūwāhi e rua i te wā kotahi; kia tino ringihia ngā rauemi whakauru i roto i te wā kua tohua, ko te ringihanga o ngā wāhanga he iti iho i te 50mm te matotoru he pai ake kia rite ki te hanganga whakarewa aunoa me te tango hau.
5. Te rahui i ngā hononga whakawhanui
Nā te mea kāore te tauwehenga whānui o te mea whakarewa i rite ki te tauwehenga whānui o te maitai, he tata ki te haurua o te maitai. I te nuinga o te wā, e whā ngā huarahi hei whakaoti i te whānui o te mea whakarewa: ko te tuatahi ko te peita i te peita uku ki runga i te mata pine me te mata whakarewa, ko te matotoru kia kaua e iti iho i te 1mm. Ko te tuarua ko te wāhanga ringihia nui, ka ringihia ki roto i ngā poraka ia 800~1000×400, ā, ka whakapirihia te rauemi hononga whānui mai i te taha kia puta atu i te hononga whānui. Ko te tuatoru ko te takai i te pepa muka uku he 2mm te matotoru ki runga i te mata o te taupoki, ngā hononga paipa taputapu, me ngā wāhanga werohanga pakitara whakarewa hei hononga whānui. Tuawhā, ka taea te whakamahi i te maripi hei tapahi i te āputa haurua-matotoru i te wā e hangaia ana te kirihou, ka taea rānei te wero i te kirihou hei whakaoti i te raruraru o te whānui.
