He mea nui te awa tiaki wai mō te tohatoha rauemi wai me te whakamakuku ahuwhenua, ā, ko tōna maimoatanga ārai-mimi e pā tika ana ki te pumau me te roa o te mahi a te awa. I ngā tau tata nei, hei momo rauemi ārai-mimi hou, kua whakamahia whānuitia te geomembrane hiato i roto i te maimoatanga ārai-mimi o ngā awa tiaki wai. Nō reira, he pai te whakamahi i te geomembrane hiato mō te maimoatanga ārai-mimi o ngā awa tiaki wai? Ka tātarihia e tēnei pepa ngā painga me ngā ngoikoretanga o te geomembrane hiato me tōna whakamahinga i roto i te maimoatanga ārai-mimi o ngā awa tiaki wai.
Tuatahi, me titiro tātou ki ngā painga o ngā geomembrane hiato. He mea hanga te geomembrane hiato i te polymer ngota me te geotextile teitei, he tino pai te mahi ārai-mimi. He iti tōna tauwehenga ārai-mimi, ka taea te ārai i te urunga wai me te whakaiti i te ngaronga turuturu o te awaawa. Hei tāpiri, he pai hoki te kaha kume me te roa o te geomembrane hiato i te whati, ka taea te urutau ki te whakarerekētanga o te raro o te awaawa me te pupuri i te pumau hanganga. I te wa ano, he āhuatanga anō hoki o te geomembrane hiato ko te ātete ki te waikura, te ātete ki te koroheketanga me te ātete ki te ultraviolet, ā, ka taea te whakamahi mō te wā roa i raro i ngā āhuatanga taiao kino.
Heoi anō, kei reira ētahi ngoikoretanga o ngā geomembrane hiato. Tuatahi, he uaua te hanganga, ā, me whai rōpū hanga ngaio me te hangarau hanga. Me whakarite te whakatakotoranga o ngā geomembrane hiato kia papatahi, kia kiato hoki te mata o te membrane, ki te kore ka pāngia tōna pānga ārai-mimi. Hei tāpiri, me tūpato hoki te geomembrane hiato kia kore ai e werohia, e waruhia rānei e ngā mea koi i te wā e kawe ana, e penapena ana hoki, kia kore ai e pakaru tōna āhua.
I roto i te maimoatanga ārai-mimi o ngā awa tiaki wai, he pai ngā painga o te whakamahinga o te geomembrane hiato. Tuatahi, ka taea e te geomembrane hiato te ārai i te turuturu i raro i te awa me te whakapai ake i te kaha rokiroki wai me te whai huatanga o te whakamakuku o te awa. Tuarua, he poto te wā hanga o te geomembrane hiato, ka taea te whakapoto i te wā hanga me te whakaiti i te utu o te kaupapa. Hei tāpiri, he roa te ora mahi o te geomembrane hiato, ka taea te whakaiti i te maha o ngā whakatikatika me ngā whakakapinga o ngā awa me te whakaiti i ngā utu tiaki.
Heoi, i roto i te maimoatanga ārai-mimi o ngā awa tiaki wai, me aro atu hoki tātou ki ētahi herenga o ngā geomembrane hiato. Hei tauira, i te wā e whakatakoto ana i te geomembrane hiato, me whakarite kia papatahi te raro o te awa, ā, kia kore he mea koi e puta mai ana hei karo i te wero i te mata o te membrane. Hei tāpiri, me whakarewa te geomembrane hiato, ā, me whakau i muri i te whakatakoto kia mau ai tōna āhua me tōna pumau. Me whakamahere me te whakarite i mua i te hanganga mō ēnei whakaritenga hanga katoa.
Hei tāpiritanga, me aro atu hoki tātou ki ngā panonitanga mahi o ngā geomembrane hiato i te wā e whakamahia ana mō te wā roa. Ahakoa he āhuatanga ātete ki te koroheketanga me te ātete ki te hihi ultraviolet te geomembrane hiato, tera pea ka pāngia tōna mahi ina roa te wā e pāngia ana e ngā taiao taiao pēnei i te rā, te ua me te oneone. Nō reira, i roto i te maimoatanga ārai-mimi o ngā awa tiaki wai, me tirotiro me te tiaki tonu i te geomembrane hiato kia mau ai te pumau me te roa o tōna mahi.
Hei whakarāpopototanga, he painga me te whaihua te whakamahi i te geomembrane hiato mō te maimoatanga ārai-mimi o ngā awa tiaki wai. He mea nui te geomembrane hiato i roto i te maimoatanga ārai-mimi o ngā awa tiaki wai nā te mea he pai te mahi ārai-mimi, he pai te urutau me te roa o te ora ratonga. Heoi, me mōhio anō hoki tātou ki ētahi herenga me ngā whakatūpato i roto i te hanganga me te whakamahinga o ngā geomembrane hiato. Nō reira, i roto i ngā tono mahi, me whiriwhiri me te whakamahi kia rite ki ngā tikanga motuhake, me te whakapakari i te whakahaere hanga me te tiaki kia pai ai te whai huatanga me te haumaru o ngā geomembrane hiato i roto i te maimoatanga ārai-mimi o ngā awa tiaki wai.
