  • Ko te hāora memeha he inenga o te nui o te hāora hau kei roto i te wai.Ko nga wai hauora e tautoko ana i te oranga me whai hāora (DO).
    Ko te Oxygen Dissolved ka uru ki te wai ma te:
    te whakauru tika mai i te hau.
    he tere te neke mai i te hau, te ngaru, te au, te haunga miihini ranei.
    ko te whakaahuatanga ora o te tipu o roto i te wai hei hua o te mahi.

    Ko te ine i te hāora rewa i roto i te wai me te maimoatanga hei pupuri i nga taumata DO tika, he mahi tino nui i roto i nga momo tono maimoatanga wai.Ahakoa e tika ana te hāora rewa hei tautoko i te oranga me nga tikanga maimoatanga, ka kino ano hoki, ka puta te waikura ka pakaru nga taputapu me te whakararu i te hua.Ka pa te hāora rewa:
    Kounga: Ko te kukū DO ka whakatau i te kounga o te puna wai.Ki te kore e nui te DO, ka kino te wai me te kino ka pa ki te kounga o te taiao, te wai inu me etahi atu hua.

    Te Tautukunga Ture: Ki te u ki nga ture, he maha nga wa e tika ana kia mau te wai para o DO i mua i te tukunga ki roto i te awa, roto, awa, ara wai ranei.Ko nga wai hauora e tautoko ana i te oranga me whai hāora memeha.

    Whakahaere Tukanga: Ko nga taumata DO he mea nui ki te whakahaere i te maimoatanga koiora o te wai para, tae atu ki te waahanga biofiltration o te hanga wai inu.I etahi tono ahumahi (hei tauira, te hanga hiko) he kino te DO mo te hanga mamaoa, me tango, me kaha te whakahaere i ona kukū.
