Ngā Āhuatanga
He pai te mahi ārai-mimi:Ka taea e ia te ārai i te turuturu o te wai, te whakaiti nui i te para me te ngaronga o ngā rauemi wai, ā, ka taea te whakamahi mō te maimoatanga ārai-turuki o ngā kaupapa tiaki wai pēnei i ngā puna wai, ngā puna kaukau me ngā awaawa, tae atu ki ngā kaupapa tiaki taiao pēnei i ngā whenua ururua me ngā whare maimoatanga paru.
Te pakari kaha:He pai tōna ātete ki te waikura, ki te koroheketanga, ā, ki te hihi ultraviolet. Ka taea te whakamahi mō te wā roa i roto i ngā taiao waikawa-pūtake rerekē me ngā āhuatanga taiao uaua, ā, ko tōna roanga mahi he neke atu i te 20 tau.
Te kaha kume teitei:Ka taea e ia te tu atu i ngā kaha kume me te pēhanga nui, ā, kāore e ngāwari te whakapēhanga. I te wā e whakatakotoria ana, me te wā e whakamahia ana te kaupapa, ka taea e ia te pupuri i te hanganga pai, ā, he pai mō ngā momo āhuatanga turanga me ngā hanganga hangarau.
Hanganga watea:He māmā, he ngāwari hoki te hanga, he ngāwari ki te kawe, ki te whakatakoto me te hanga. Ka taea te whakatakoto ā-ringa, ā-mīhini rānei, ka taea ai te penapena i ngā utu mahi me te wā, me te whakapai ake i te whai huatanga o te hanga.
He pai mō te taiao, ā, kāore he paitini:He pai mō te taiao, ā, e kore e whakapoke i te oneone, i ngā puna wai me te taiao e karapoti ana, e tutuki ai ngā whakaritenga tiaki taiao o ngā hanganga hangarau o ēnei rā.
Ngā Āpure Tono
Ngā kaupapa tiaki wai:I roto i te hanganga o ngā whare tiaki wai pēnei i ngā puna wai, ngā tāhuna, ngā awaawa me ngā parapara, ka whakamahia hei ārai i te turuturu wai, hei whakapai ake i te haumaru me te roa o ngā kaupapa, me te whakarite kia whai hua te whakamahinga o ngā rauemi wai.
Ngā kaupapa tiaki taiao:I roto i te pūnaha ārai-mimi o ngā whenua ururua, ka taea e ia te ārai i te mimiti o te wai para ki roto i ngā wai o raro whenua, me te ārai i te parahanga o te oneone me te wai whenua. I roto i ngā whare pēnei i ngā puna kaukau me ngā puna whakahaere o ngā whare tukatuka para, ka taea hoki e ia te mahi ārai-mimi hei whakarite i te mahi noa o te tukanga maimoatanga para.
Ngā kaupapa kawe waka:I roto i te hanganga o ngā papa raro o ngā huarahi tere me ngā rēriwe, ka taea te ārai i te wai kei mimiti ki roto i te papa raro, te karo i ngā raruraru pēnei i te taunga me te whakarerekētanga o te papa raro i puta mai i te rumaki wai, me te whakapai ake i te pumau me te roa o te ora o ngā rori.
Ngā kaupapa ahuwhenua:Ka whakamahia i roto i ngā awaawa, ngā roto me ētahi atu whakaurunga o ngā pūnaha whakamakuku ahuwhenua, ka taea te whakaiti i te turuturu o te wai, te whakapai ake i te whai huatanga o ngā rauemi wai, me te penapena i te wai whakamakuku. Ka taea hoki te whakamahi hei rongoā ārai-turuki i ngā pāmu whakatipu hei ārai i te turuturu o te wai para whakatipu kei poke i te taiao e karapoti ana.
Ngā kaupapa keri:He wāhanga nui o ngā kaupapa keri te maimoatanga ārai-mimi o ngā puna paru. Ka taea e ngā geotextile ārai-mimi te ārai i ngā matū kino o ngā paru kei mimiti ki roto i te whenua, te karo i te whakapoke i te oneone me ngā wai e karapoti ana, ā, i te wa ano ka whakaiti i te ngaronga wai o ngā puna paru me te whakapai ake i te pumau o ngā puna paru.
