I kēia manawa, ke hoʻokō nei koʻu ʻāina i ka hoʻopau ʻana i nā ʻōpala home, a e emi mālie ka ʻōpala o nā ʻōpala mua. Akā, pono i kēlā me kēia kūlanakauhale ma kahi o hoʻokahi ʻāina ʻāina no ka hoʻopaʻi ʻana i ka pilikia a me ka ʻāina lehu ahi. Ma ka ʻaoʻao ʻē aʻe, i kēia manawa he nui nā ʻōpala paʻa paʻa i hoʻopiha ʻia a pono e pani ʻia. No laila, i ka wā e hiki mai ana, e loaʻa i nā geosynthetics nā manaʻo mākeke nui i ka pani ʻana o nā ʻōpala paʻa paʻa a me ka uhi pōkole o nā ʻāina lawelawe.
ʻO ka mea i kapa ʻia ʻo ka uhi pani ʻana, ʻo ia hoʻi, i ka wā e hoʻopiha ʻia ai ka ʻōpala ʻōpala paʻa, pono ke kūkulu ʻia kahi hale uhi hoʻohui ma luna o kona ʻili e pale ai i ka infiltration wai a me ke kahe ʻana o ke kinoea, a hiki ke kanu ʻia nā mea kanu no ka ʻōmaʻomaʻo a me ka hoʻihoʻi ʻana. ʻEkolu ʻano nui o nā mea geosynthetic i hoʻohana ʻia ma ka uhi kahua: polyethylene haʻahaʻa haʻahaʻa (LDPE) geomembrane, bentonite pale wai wai a me ka ʻupena wai hoʻohuihui. I waena o lākou, he ductility maikaʻi ka LDPE geomembrane, ʻaʻole maʻalahi e haehae, a hiki ke hana maikaʻi i ka anti-seepage a me ka hoʻopaʻa ʻana i ka ea. He maikaʻi nō hoʻi nā waiwai pale anti-seepage o ka pale wai wai bentonite. Ke hoʻohālikelike ʻia me ka geomembrane, ʻaʻole ia e ʻoki loa i ka mahu wai ma lalo o ka uhi uhi, ʻoi aku ka maikaʻi o ka ulu ʻana o nā mea kanu.
ʻO ka uhi paʻa ʻana o nā ʻōpala paʻa paʻa i loko o ka lawelawe ʻo ia ka uhi ʻana i nā ʻōpala i hōʻike ʻia me nā geosynthetics i nā wahi i hoʻopaʻa ʻole ʻia no ka manawa pōkole e hōʻemi i ka komo ʻana o ka wai ua a me ke kahe ʻana o ke kinoea. Hoʻohana mau ʻia ka uhi manawaleʻa i nā papahana lapaʻau kahua pollution no ka pale ʻana i nā kinoea ʻino mai ka holo ʻana i ka lewa. I nā lā mua, hoʻohana mau ʻia nā tarpaulins, nā kiʻiʻoniʻoni, a me nā mea ʻē aʻe no ka uhi ʻana no ka manawa pōkole, akā hiki i nā pilikia e like me ka maikaʻi ʻole o ka anti-seepage a me ka hopena ea-sealing a me ka hikiwawe ʻana o nā welds. I kēia manawa, he kiʻekiʻe a kiʻekiʻe aʻe nā koi no ka hoʻopaʻa ʻana. Hoʻohana kekahi mau ʻāina i ka 1mm mānoanoa HDPE geomembrane no ka uhi manawa. ʻOi aku ka maikaʻi o ka hopena o ka hoʻopaʻa ʻana.
