Ukukhethwa kweZixhobo kunye neenkqubo zoKwenziwa kweMveliso:
Ii-geomembrane ze-HDPE (i-High-Density Polyethylene): Zizinto ezisetyenziswa kakhulu ezaziwa ngokuchasana nokugqwala kakuhle kunye neempawu zokulwa nokwaluphala, nto leyo eyenza ukuba zifaneleke kwiifama ezininzi zokuzalisa.
Ukukhetha Inkqubo: Iigeomembranes eziveliswa ngenkqubo yefilimu evuthuziweyo. zibonisa ubukhulu obufanayo kunye neempawu zokutsalwa, kunye nokumelana okuphezulu kokubhoboza; ezo zenziwe ngenkqubo yokulinganisa zinomgangatho ogudileyo, nangona ukufana kwazo kobukhulu kusenokungahambelani kangako.
Ukuqwalaselwa koMgangatho neMigangatho: Beka phambili ii-geomembranes ezihambelana nemigangatho yesizwe (umz., GB/T 17643-2011) okanye imigangatho yokwakha izixeko (umz., CJ/T 234-2006) ukuqinisekisa ukuba iipropati ezinje ngokukwazi ukuvuza kwamanzi, amandla okutsalwa, kunye nokumelana nokugqwala ziyahlangabezana nemilinganiselo efunekayo.
Kuphephe ukusebenzisa ii-geomembranes ezenziwe ngezinto ezisetyenzisiweyo; endaweni yoko, beka phambili ezo zenziwe ngezinto ezingazange zisetyenziswe ukuqinisekisa ukuba imveliso ihlala ixesha elide kwaye ikhuselekile.
Ubukhulu buphawu olubalulekileyo lokusebenza kakuhle nokuqina kokuvuza kwamanzi. Izinto ezincinci kakhulu zidla ngokukrazuka, ngelixa izinto ezinkulu kakhulu zibangela inkcitho engeyomfuneko; ngoko ke, ubukhulu kufuneka bukhethwe ngokuchanekileyo ngokusekelwe kwisicelo esithile sokuzala:
Amachibi Okufuya Amachibi Amancinci, Anganzulu (Ubunzulu bamanzi ≤ 1.2m) kunye namachibi okufuya abantwana: Khetha 0.5–0.75mm.
Amachibi eentlanzi aqhelekileyo kunye namachibi eeShrimp (Ubunzulu bamanzi yi-1.2–2.5m): Khetha i-1.0–1.5mm ukuze ufumane umlinganiselo ongcono weendleko kunye nokusebenza.
Amachibi Amanzi Anzulu (Ubunzulu bamanzi ≥ 2.5m) kunye Neendawo Ezikhethekileyo Zokuzalela (umz., iifudo ezinamaqokobhe athambileyo, iikrayfish): Khetha i-1.5–2.0mm ukuze ukwazi ukumelana nokubhoboza ngcono.
Inkunkuma yemfuyo kunye neenkukhu/imigodi yomgquba kunye neebhayogas zokugaya Ngenxa yendawo enobungozi kakhulu kunye nokuchaphazeleka lula zizinto eziqinileyo, ubukhulu obuncinci be-1.0mm buyimfuneko; uhlobo olujiyileyo lwe-1.5mm luyacetyiswa kakhulu.
Amanzi okugcina amanzi kunye nemijelo yokunkcenkceshela. Kwinzulu yamanzi engaphantsi kwe-2m, khetha u-0.5–0.75mm; kwinzulu yamanzi ephakathi kwe-2m kunye ne-4m, khetha u-0.75–1.0mm; kwimisele emikhulu, khetha u-1.5mm okanye otyebileyo.
