Papa rerenga wai momo-pepa
Whakaahuatanga Poto:
Ko te papa waikeri momo-pepa he momo rauemi geosynthetic e whakamahia ana mō te waikeri. He mea hanga i te kirihou, i te rapa, i ētahi atu rauemi polymer rānei, ā, he hanganga rite ki te pepa. He kakano motuhake, he pūwero rānei tōna mata hei hanga i ngā awa waikeri, ka taea te ārahi pai i te wai mai i tētahi wāhi ki tētahi atu. He maha ngā wā e whakamahia ana i roto i ngā pūnaha waikeri o ngā mahi hanga, ā-tāone, māra me ētahi atu mahi hangarau.
Ko te tikanga he mea hanga ki ngā rauemi polymer pēnei i te kirihou me te rapa, me ngā rārangi teitei, totohu rānei i runga i tōna mata hei hanga i ngā awaawa wai. Ka taea e ēnei rārangi te hanga i te āhua o ngā tapawhā rite, ngā pou, ētahi atu āhua rānei, ka taea te ārahi pai i te rere o te wai. I taua wā, ka whakanui ake i te horahanga pā i waenga i te papa wai me te rauemi e karapoti ana, ka whakapai ake i te pai o te wai. Hei tāpiri, ko ngā taha o te papa wai momo pepa he mea hanga ki ngā hanganga he ngāwari ki te hono, pēnei i ngā mokowā kāri, i ngā whitiki rānei, he watea mō te hono i te wā hanga hei hanga i tētahi pūnaha wai nui.
Ngā painga mahi
He pai te pānga o te rerenga wai:He maha ngā awa waikeri o roto, ka taea te kohikohi me te tuku i te wai kia ōrite, kia tere ai te rere o te wai mā te papa waikeri, ā, kia kore ai e mimiti te wai.
Te whakatakotoranga ngāwari:He iti noa iho ngā rahi, ā, ka taea te hono ngāwari me te whakatakoto kia rite ki te āhua, te rahi, me ngā whakaritenga motuhake o te papa hanga. He tino pai mō ētahi wāhi he āhua koretake, he wāhi iti rānei, pērā i ngā kokonga o ngā whare me ngā māra iti.
Te kaha pēhi teitei:Ahakoa he pepa te āhua, mā te whiriwhiri rauemi me te hoahoa hanganga e tika ana, ka taea e ia te tu atu i tētahi pēhanga, ā, kāore e ngāwari te whakapēke i te wā e whakamahia ana, kia mau ai te pumau me te pono o te pūnaha waikeri.
Ātete ki te waikura, ā, ātete ki te koroheketanga:He pai ngā āhuatanga ātete o ngā rauemi pūmua ki te waikura, ki te koroheketanga hoki, ā, ka taea te whakamahi mō te wā roa i raro i ngā āhuatanga taiao rerekē, kāore hoki e pāngia ngāwari e ngā matū, te wai, ngā hihi ultraviolet, me ētahi atu āhuatanga o te oneone, ā, he roa te ora mahi.
Ngā āpure tono
Hangarau hanga:He maha ngā wā e whakamahia ana i roto i ngā pūnaha waikeri o ngā rūma o raro, ngā māra tuanui, ngā papa waka, me ētahi atu wāhanga o ngā whare. I roto i ngā rūma o raro, ka taea e ia te ārai i te wai whenua kei uru ki roto, ka tiaki i te haumaru hanganga o te whare. I roto i ngā māra tuanui, ka taea e ia te tango i te wai nui, te karo i te waipuke i ngā pakiaka o ngā tipu, ka arahi pea ki te pirau, ā, ka whakarato i te taiao tipu pai mō ngā tipu.
Te hangarau ā-rohe:Ka taea te whakamahi hei waikeri i ngā papa whenua o te rori, ngā tapawhā, ngā ara hikoi, me ētahi atu wāhi. I roto i te hanganga rori, ka āwhina i te mimiti i te wai i roto i te papa whenua, ka whakapai ake i te pumau me te kaha o te papa whenua, ka whakaroa hoki i te roa o te ora o te rori. I roto i ngā tapawhā me ngā ara hikoi, ka taea e ia te mimiti tere i te wai ua, te whakaiti i te waipuke o te whenua, me te whakahaere i te haere a te hunga hikoi.
Te hangarau whenua:He pai mō te whakaheke wai i ngā moenga putiputi, i ngā puna putiputi, i ngā wāhi matomato, me ētahi atu whenua. Ka taea e ia te pupuri i te makuku tika o te oneone, te whakatairanga i te tipu o ngā tipu, me te ārai i ngā kino o te whenua i puta mai i te waipuke.
