Ki te whakarite ngā āhuatanga whakamarie i roto i te whare whenua titau te pūnaha parakaingaki pai-mahi, i te mea e taea ki te waihanga anake te tank ero, kahore te kutētē. I roto i taua whakaaro, kahore he tukanga anaerobic i roto i tenei hononga i roto i te mahi e kore e hanga i hauwai sulfide, i roto i te tahuri, arata'i ki haumaru tino. E tino māmā ki te whakamahi ēnei wae. hiahiatia ratou horoi te ki kia anake he wa torutoru i roto i te tau. Na reira, tāke ero kahore kutētē ki hoatu riro te otinga tino pai mā te tuku wai whakanoa pai. Ko tōna whakamahi tukua e te nuinga whakaora i runga i te pūngao hiko, me te köurarangi.
Heoi hangarua para ururua noa e kore ero taea tino kahore köurarangi, mai kore e ururua ngā etahi mea organic, pōpopo. i roto i te ngaa hoki i roto i te maha o poke kore e wairewa e i roto i te wai i te katoa. Na reira, etahi wa i muri tonu tonu waipara e piki i roto i ruma motuhake. Ka maoro, i ki kia to'o toenga o taua poke. Heoi, meatia tenei e nui iti pinepine i te kutētē puunaha i te tikanga raupo.
Hei matau aha te mea he tank ero waho te papu, he mea e tika ana ki te whakaaro i te parau tumu o te teihana paerewa hohonu horoi. ngā ratou: te putorino kai, ero ruma aerator biogenerator, clarifiers tuarua, me te tuatoru, me te ngongo putanga. Ahakoa e karangatia enei wae motuhake, e rapu ratou te aroaro o te mana hiko ki te whakaoti i te mahi. Ko e tika ana ki te compressors whakahaere o nāianei e tuku hau ki te aerators tenei. I roto i te tahi mau wae te köurarangi o te wai e wahi i te tikanga o airlifts, engari he ano hoki ratou nuinga o ti'aturi i runga i te hiko.
A, no te mahi i waho i te köurarangi tank ero, kua tonoa effluents katoa ki te ruma tangohanga, i te mea te nuinga o neke atu i te etahi. Ko tōna misioni he ki te whakaemi ururua i roto i te puka wai, me te ki whai wāhi i roto i te fakamahino o te wai. I roto i te paparanga o runga e kohia poke marama pērā i te ngako me te warowaihā rewa. I muri i te tetahi wa taui tona hanganga.

Kei te āta te wai haamaramaramahia haere i runga i.
Kotahi, e rua e mahi ana i te tau te kutētē tāke ero. utu Pūrere whai wāhi nui i roto i te maha o ngā mahi e taea te mahi mau i te ringa. I roto i te wā tino, mo tenei reira he maha ngā ratonga whai wāhi i roto i te tukunga i ēnei sewers. I etahi wa i reira ka tae mai tohunga, me te tikanga o te papu awakeri ka pahuatia nga tirotiro o te raupo. I muri horoi ki te tāutanga pūrere motuhake he rite ano. O te akoranga, te utu o ngā pūrere e kore e e rapua e köurarangi auau, nui ki runga ake i ngā hiri noa.
