Ka tukatukahia te wai mā te mīhini mā te wehewehe i te paru ki ngā totoka me ngā wai.

● Ka wehea te paru, ka horoi anō i a ia anō i te wā kotahi hei ārai i te aukati me te horoinga o muri

● Mā ngā kōpae porowhita ka taea te kawe i ngā kawenga nui ake.

● Ka taea te whakarite kia rite ki ngā momo maimoatanga me ngā kaupapa rerekē.

● He hanganga māmā mō te tiaki ngāwari.

Ko te Whakarewa Hau Whakarewa (DAF) he tikanga whakarewa whai hua mō te whakamārama i te wai. Ko te kupu e pā ana ki te tikanga whakaputa whakarewa mā te whakarewa i te hau i roto i te wai i raro i te pēhanga, kātahi ka tukuna te pēhanga. Ina tukuna te pēhanga, ka nui rawa te hau o te otinga i te mea ka puta he miriona mirumiru iti. Ka piri ēnei mirumiru ki ngā matūriki katoa i roto i te wai, ka iti iho tō rātou mātotoru i te wai. Ka hangaia e te hau i tukuna he mirumiru iti e piri ana ki te mea iri, ka rere te mea iri ki te mata o te wai, ā, ka taea te tango mā te taputapu tango wai.

Ko te Wāhanga Whakarite Pūmua Aunoa he taputapu ka taea te whāngai me te whakarewa i te paura matū maroke, kātahi ka whakaputa aunoa me te haere tonu i te wai matū.

Ko te Lamella clarifier inclined plate settler (IPS) he momo settler i hangaia hei tango i ngā matūriki mai i ngā wai.

He maha ngā wā ka whakamahia ēnei i roto i te maimoatanga wai tuatahi hei whakakapi i ngā tāke taunga tuku iho. Ko te tikanga horoi wai ngongo piko me te pereti piko ka hangaia mā te whakatakoto i te paparanga whakatārewatanga paru ki runga ake i te pereti piko o te ngongo piko me te koki piko o te 60 nekehanga, kia kohia ai te mea i tārewatia i roto i te wai mata ki te mata o raro o te ngongo piko. Whai muri i tēnā, ka hangaia he paparanga paru angiangi, ka paheke ki te paparanga whakatārewatanga paru paru i muri i te whakawhirinaki ki te mahi a te kaha ā-papa, kātahi ka totohu ki roto i te peere kohikohi paru, kātahi ka tukuna ki roto i te puna paru e te paipa tuku paru hei maimoatanga, hei whakamahi whānui rānei. Ka piki haere te wai ma i runga ake nei ki te paipa kohikohi wai hei tuku, ka taea te tuku tika, te whakamahi anō rānei.

He momo wehewehe motuhake me ngā āhua kōhao te kōpae mirumiru pai, ka taea te hora i ngā mirumiru hau ki roto i tētahi tauira tino pai, ōrite hoki, kia pai ai te whakawhiti hāora. Mā te takirere tirotiro tino whai hua, kua whakauruhia hoki, ka taea te kati ngāwari i ngā rohe hau mō ngā mahi hau-whakakā/whakaweto. Ka taea te whakahaere i runga i te whānuitanga o ngā rerenga hau me te iti o te tiaki mō te mahi roa.

1. Me āhua taratara te mata o ngā mea koiora kia tere ai te hanga i tētahi mata koiora hohe (kiriata koiora).

2. Kia nui te pūngao hei whakarite kia pai te tuku hāora ki te kiriata koiora.

3. Ka taea e ngā kongakonga kiriata koiora o te whare paru te haere mā roto i te pāpāho katoa, me ngā āhuatanga horoi-ake anō hoki.

4. Mā te hanganga miro porowhita, porotītaha rānei ka nui ake te horahanga mata koiora motuhake.

5. Kāore e pirau i ngā āhuatanga koiora me ngā āhuatanga matū, he ātete pumau ki ngā hihi UV, ā, ka taea hoki te aro atu ki ngā huringa o te pāmahana.

6. He māmā te tāuta ki roto i tētahi momo tāke, i tētahi pūwhakaora koiora rānei, me te kore e moumou wāhi me ngā rauemi.

Ko te pānga o te taura koiora ki te tukatuka i ngā poke me ngā hau para e puta mai ana i te tangata i roto i te mahi whakaputa me te oranga mā te tikanga whakahāngaitanga pa koiora, me te whakamahi i te maimoatanga taiao hei tiaki i te taiao kia tutuki ai te rere o te taiao. Ka taea e ia te whakatere i te rere o te taiao me te whakapai ake i te kaha tukatuka o ngā taputapu maimoatanga koiora o nāianei, kia iti ai te nui o te kawenga taiao.
