Whakangawari waie whakamahia ana hei whakaiti i te pakeketanga o te wai mata hei whakatutuki i te kaupapa o te whakangawari i te wai mārō, kia kore ai e memeha te warowaihā i roto i ngā paipa, ngā ipu, me ngā kohua,e whakamahia whānuitia ana i roto i ngā mara ahumahi me ngā mara whare hei whakaiti i te hanganga unahi me te whakapai ake i te kounga o te wai. Anei ētahi kōrero taipitopito mō te whakangawari wai:

1. Te kaupapa mahi

Ko te tikanga matua o te whakangawari wai ko te whakangawari i te wai mā te hangarau whakawhiti katote. Ko te kaupapa matua ko te whakamahi i te kapia whakawhiti katote konutai hei whakakapi i ngā katote konupūmā (Ca²⁺) me te konupora (Mg²⁺) i roto i te wai ki ngā katote konutai (Na⁺), ā, ka whakaitihia te pakeke o te wai.

Tomokanga: Ka tomo te wai mārō ki te whakangawari wai.

Tukanga whakawhiti: Ka pāngia ngā katote konutai i runga i te kapia e ngā tauhohenga whakawhiti me ngā katote konupūmā me te konupora i roto i te wai.

I muri i te maimoatanga, he wai ngohengohe e puta mai ana.

2. Ngā wāhanga matua

Tāke kapia: kī tonu i te kapia whakawhiti kationi, e whakamahia ana mō te whakawhiti katote.

Pouaka tote: he pouaka tote kua hangaia anō (ko te tote tepu te tikanga) hei whakaora i te kaha whakawhiti o te kapia.

Kaiwhakahaere: e whakahaere ana i te huringa whakahaere, te wā whakahou, me te tere rere o te whakangawari wai.

3. Ngā Painga

Te aukati i te unahi: te whakaiti i te kohikohinga unahi i roto i ngā paipa, ngā whakamahana wai, me ētahi atu taputapu.

Whakapai ake i te hua horoi: Ka taea e te wai ngohengohe te whakarewa pai ake i te hopi horoi, te hopi rānei, ka pai ake te pai o te horoi.

Whakaroa i te roa o te ora o ngā taputapu: Whakaitihia te waikura o ngā taputapu mā te tauine, ā, whakaroahia tōna roanga mahi.

Te whakapai ake i te kounga o te wai: te whakangawari ake i te wai, me te whakarite kia pai mō te hunga kiri tairongo.

4. Ngā Āpure Tono

Te nuinga e whakamahia ana i roto i te wai whāngai pōro ahumahi,hauhautanga,wai whakanikoniko mō te pourewa whakamatao, wai tukatuka kai, me ētahi atu
