Ko te hāora rewa he ine i te nui o te hāora hau kei roto i te wai. Ko ngā wai hauora e taea ai te tautoko i te ora me whai hāora rewa (DO).
Ka uru te hāora rewa ki te wai mā:
te mimiti tika mai i te āhuarangi.
te nekehanga tere mai i ngā hau, ngā ngaru, ngā ia, te hau rānei a te mīhini.
te whakaahua-ā-ira o ngā tipu wai hei hua taha o te tukanga.
Ko te ine i te hāora rewa i roto i te wai me te maimoatanga hei pupuri i ngā taumata DO tika, he mahi nui i roto i ngā momo mahi maimoatanga wai. Ahakoa he mea nui te hāora rewa hei tautoko i te oranga me ngā tukanga maimoatanga, ka taea hoki te kino, ka puta he waikura ka pakaru ngā taputapu me te whakararu i te hua. Ka pā te hāora rewa ki:
Kounga: Ko te kukū o te DO ka whakatau i te kounga o te wai pūtake. Ki te kore e nui te DO, ka piro te wai, ka kore e hauora, ka pā ki te kounga o te taiao, te wai inu me ētahi atu hua.
Te Whakatutukitanga ki ngā Ture: Hei whakatutuki i ngā ture, me whai kukū DO te wai para i mua i te tukunga ki te awa, ki te roto, ki te awaawa, ki te ara wai rānei. Me whai hāora wairewa ngā wai hauora hei tautoko i te ora.
Whakahaere Tukanga: He mea nui ngā taumata DO hei whakahaere i te tukatuka koiora o te wai para, tae atu ki te wāhanga tātari koiora o te hanga wai inu. I roto i ētahi tono ahumahi (hei tauira, te hanga hiko) he kino te DO mō te whakaputanga mamaoa, me tango atu, ā, me tino whakahaere i ōna kukū.
