Ko te wāhi whakamātau ake i ngā āhua wai o te kamupene he whakamātau i te mahi ake o ngā tāputapu wai e hāpai ai te taiao kia tūpato ki ngā tānagamanga taiao me te kounga āhua tiketike. Ahakoa mō ngā tāone e noho pōpō ana, ngā tāpawhā here o ngā kamupene, i te hunga noho wāhi noho, ēnei tāputapu wai e hāpai ai te taiao e whakapai ake ana i te taiao ki tā rātou āhua, ā, e whakawhitinga hoki i te tautohetohe ki ngā tikanga kākāriki. Ko te kapa hoahoa e tiaki ana kia kaua ngā tāputapu wai e hāpai ai te taiao e iti i te āhua, e hanga ana i ngā whakaaturanga whakamiharo e rite ana ki te taiao. Mā te kōwhiri i ngā tāputapu wai e hāpai ai te taiao mai i tēnei kamupene, ka taea e ngā kaihoko te ngakau pōuri o te āhua o te tāpawhā wai i te wā kotahi me te āwhina i te wāhi e āki ai te roa, e whakapono ai i ēnei tāputapu wai e hāpai ai te taiao hei kōwhiringa hāngai me te hāngai ki ngā wāhi hou.
