Te mahi a te papa rerenga ngaru hiato

He rauemi e whakamahia whānuitia ana ngā whāriki rerenga ngaru hiato i roto i te hangarau. Nā, he aha ā rātou mahi?

1. Hanganga me ngā āhuatanga o te whāriki rerenga ngaru hiato

Ko te papa rerenga wai ngaru hiato he hanganga me te awaawa ngaru pumau e honoa ana e te tukanga whakatakoto rewa. Nō reira, he tino pai te ātete ki te pēhanga o te papa rerenga wai, he nui te kiato whakatuwheratanga, ā, he maha ngā mahi kohikohi wai me te rerenga wai whakapae. Ka whakakotahihia hoki e ētahi papa rerenga wai ngaru hiato ngā papa mata polypropylene toru-ahu me ngā geotextiles kore-whatu. Mā te hononga wera, ka taea te hanga i tētahi hanganga rerenga wai toru-ahu e tātari whakamuri ana, e rerenga wai ana, e tiaki ana hoki. Ehara i te mea ka whakarei ake tēnei hanganga hiato i te kaha me te roa o te papa rerenga wai, engari ka whakapai ake hoki i tōna pai o te rerenga wai me te whānuitanga o te whakamahinga.

2. Ko te mahi matua o te papa waikeri ngaru hiato

1. Te rerenga wai whai hua

Ka taea e te hanganga ngaru o te papa rerenga ngaru whakakotahi te whakanui ake i te piko o te ara rere wai, te whakaroa i te tere o te rere o te wai, me te whakapai ake i te pai o te rerenga wai. Kua hangaia te awa rerenga wai o roto hei kohikohi me te whakaheke tere i te wai whenua, i te wai ua rānei, hei whakaiti i te makuku o te oneone, hei ārai hoki i te waipuke. Nō reira, ka taea te whakamahi i roto i ngā kaupapa tiaki wai, te hanga rori, te ārai wai i raro i te whenua me ētahi atu mara.

2. Whakapai ake i te pumau o te hanganga

Ka taea e te hanganga kōpikopiko te whakanui ake i te horahanga pā i waenga i te papa rerenga wai me te oneone e karapoti ana, te whakanui ake i te waku, me te whakarei ake i te pumau whānui o te hanganga. Mā te rerenga wai, ka taea te whakaiti i te nui o te makuku o te oneone, ā, ka taea te whakau i te pumau o te turanga me te pari. I roto i te tiaki pari o ngā huarahi tereina me ngā ara rerewē me ētahi atu ara waka, mā te whakamahi i ngā whāriki rerenga wai ngaru whakakotahi ka taea te ārai i te hinganga o te pari me te horo o te oneone, ā, ka whakarite i te haumaru o te taraiwa.

3. Te wehe me te tiaki

Ka taea e te papa rerenga wai ngaru whakakotahi te mahi hei paparanga wehe i waenga i ngā rauemi rerekē hei ārai i te whakaranu me te poke i waenga i ngā rauemi rerekē. I roto i te hangarau o raro whenua, ka taea te mahi hei paparanga ā-wai hei tiaki i te hanganga o raro whenua mai i te horo o te makuku. Ka taea hoki e te papa rerenga wai te marara me te whakaiti i te pēhanga ki runga i te turanga mā te kawenga o runga, me te whakapai ake i te kaha o te turanga ki te kawe.

4. Te tiaki taiao me te whakaora rauropi

I roto i ngā kaupapa tiaki taiao pēnei i te whakaora taiao me ngā whenua ururua, ka taea te whakamahi i ngā whāriki rerenga ngaru hiato hei wehe i ngā poke me te whakatairanga i te whakaora taiao. Mā tōna ātete ki te waikawa me te kawakore me te ātete ki te waikura ka taea te pupuri i te mahi pumau o ngā whāriki rerenga wai i roto i ngā taiao kino, ka whakarato i te tautoko rerenga wai mō te wā roa me te pono mō ngā kaupapa whakaora taiao.

III. Te tono

1. I roto i ngā kaupapa tiaki wai pērā i ngā puna wai, ngā pareparenga, me te whakahaere awa, mā te whakamahi i ngā whāriki rerenga wai ka ārai i ngā waipuke, ka tiaki i ngā pareparenga, ka whakau hoki i ngā awaawa.

2. I roto i te hanganga o ngā huarahi tere, ngā ara rerewē me ētahi atu hanganga kawe waka, ka taea e ngā whāriki waikeri te whakapai ake i te pumau me te haumaru o ngā pari.

3. I roto i ngā kaupapa ārai wai me te rerenga wai o ngā hanganga raro whenua pērā i ngā rūma o raro whenua me ngā karāti raro whenua, ka taea hoki te whakamahi i ngā whāriki rerenga wai ngaru hiato.
