Hei whakaarakōura, me whakaara wai koe i te tuatahi. I roto i te tukanga katoa o te whakatipu kōura, he mea tino nui te whakahaere i te kounga o te wai. Ko te tāpiri me te whakawhiti wai tētahi o ngā huarahi māmā ki te whakahaere i te kounga o te wai. Me whakawhiti wai te puna kōura? E kī ana ētahi he tino pakarukaru ngā kōura. Ko te whakawhiti i ngā tuara hei whakaoho i ngā kōura ki te anga ka ngoikore te tinana, ā, ka pāngia e te mate. E kī ana ētahi kāore e taea te kore e whakawhiti i te wai. I muri i te wā roa o te whakatipu, he eutrophic te kounga o te wai, nō reira me whakawhiti te wai. Me whakawhiti te wai i roto i te tukanga whakatipu kōura? I raro rānei i ngā āhuatanga ka taea te whakawhiti i te wai, ā, i raro i ngā āhuatanga kāore e taea te whakawhiti i te wai?

 

E rima ngā whakaritenga me tutuki mō te whakawhiti wai tika

1. Kāore ngā kōura i te wā tino pai opupuhi, ā, he ngoikore tō rātou tinana i tēnei wā hei karo i te ahotea nui;

2. He hauora te tinana o ngā kōura, he ora pai, he kaha ki te kai, ā, kāore he mate;

3. Kua whakamanahia te puna wai, he pai ngā āhuatanga kounga wai o tai, he noa ngā tohu ā-tinana me te matū, ā, he iti noa te rerekētanga mai i te tote me te pāmahana wai i roto i te puna kōura;

4. He momona te wai o te roto taketake, ā, he kaha te tupu o ngā rimurimu;

5. Ka tātarihia te wai e tomo mai ana ki roto i te puna kōura mā te whakamahi i tētahi mata matotoru hei ārai i ngā ika me ngā hoariri o te ngahere kei uru ki roto i te puna kōura.

Me pēhea te tātari me te whakawhiti wai i ia wāhanga mā te pūtaiao

1) Te wā whakatipu wawe. Ko te tikanga, ko te wai anake ka tāpirihia, engari kāore he rerenga wai, ka taea te whakapai ake i te pāmahana o te wai i roto i te wā poto rawa, ā, ka whakatipu i ngā rauropi mōunu me ngā rimurimu whai hua.

Ina tāpirihia te wai, ka taea te tātari mā te whakamahi i ngā paparanga e rua o ngā ārai, kia 60 ngā mata mō te paparanga o roto, kia 80 ngā mata mō te paparanga o waho, kia kore ai e uru ngā rauropi hoariri me ngā hua ika ki roto i te puna kōura. Tāpirihia he wai mō te 3-5cm i ia rā. I muri i ngā rā 20-30, ka taea e te hohonutanga o te wai te piki haere ki te 1.2-1.5m mai i te 50-60cm tuatahi.

2) Te whakatipu uri i te wā waenga. I te nuinga o te wā, ina neke atu te rahinga wai i te 10cm, kāore e pai te whakawhiti i te mata tātari hei tango i ngā paru i ia rā.

3) Te wāhanga o muri mai o te whakatipu. Hei whakanui ake i te hāora rewa i te paparanga o raro, me whakahaere te wai o te puna kaukau ki te 1.2m. Heoi, i te marama o Hepetema, ka tīmata te heke haere o te pāmahana wai, ā, ka taea te whakanui ake i te hohonutanga o te wai kia mau tonu ai te pāmahana wai, engari kaua e neke ake i te 10cm te whakawhiti wai o ia rā.

Mā te tāpiri me te whakarerekē i te wai, ka taea e tātou te whakarerekē i te tote me te nui o ngā matūkai o te wai i roto i te puna kōura, te whakahaere i te mātotoru o ngā karengo kotahi-pūtau, te whakarerekē i te māramatanga, me te whakanui ake i te nui o te hāora rewa o te wai i roto i te puna kōura. I te wā pāmahana teitei, ka taea te whakamatao i te whakawhiti wai. Mā te tāpiri me te whakarerekē i te wai, ka taea te whakau i te pH o te wai i roto i te puna kōura, ā, ka taea te whakaiti i te nui o ngā matū paitini pērā i te hauwai whanariki me te haukini hauota, kia pai ai te noho o te kōura.
