Ama-geotextile angalukiwe avame ukusetshenziswa njengezinto zokudonsa amanzi ebunjiniyela.Ama-geotextiles angalukiwe awagcini nje ngokuba namandla okudonsa amanzi agudla umzimba ngendlela eqondile, kodwa futhi angadlala indima yokuhlunga ehlehlayo endaweni eqondile, engabhalansisa kangcono imisebenzi emibili yokukhipha amanzi kanye nokuhlunga kuhlehla.Kwesinye isikhathi, ukuze kucatshangelwe ezinye izidingo zezinto ezisebenza ngaphansi kwezimo zangempela zokusebenza, njengesidingo sokumelana nomonakalo omkhulu, ama-geotextiles alukiwe angasetshenziswa.Izinto zokwakha ze-geocomposite ezifana namabhodi okudonsa amanzi, amabhande okudonsa amanzi, namanethi okukhipha amanzi angasetshenziswa futhi uma izinto zidinga umthamo omkhulu wokudonsa amanzi.Umphumela wokudonsa amanzi we-geosynthetics uvame ukusetshenziswa kulezi zindawo ezilandelayo:
1) Igalari yokudonsa amanzi eqondile nevundlile yamadamu amadwala omhlaba.
2) Khipha amanzi ngaphansi kongqimba oluvikelayo noma ungqimba olungangenwa amanzi emthambekeni okhuphuka nomfula wedamu.
I-3) Khipha amanzi ngaphakathi kwenqwaba yomhlabathi ukuze uchithe umfutho wamanzi we-pore ngokweqile.
4) Ekulayishweni kwangaphambili kwesisekelo senhlabathi ethambile noma ukwelashwa kokulayishwa kuqala kwe-vacuum, amabhodi okudonsa amanzi epulasitiki asetshenziswa esikhundleni semithombo yesihlabathi njengemigudu yokukhipha amanzi eqondile.
5) Ukukhipha amanzi ngemuva kodonga olubambayo noma phansi kodonga olubambayo.
6) Khipha amanzi azungeze isisekelo sezakhiwo futhi ezungeze izakhiwo ezingaphansi komhlaba noma imigudu.
7) Njengesinyathelo sokuvimbela ukugeleza kwesithwathwa ezindaweni ezibandayo noma ukugcwala kukasawoti ezindaweni ezomile neziwugwadule, izingqimba ze-capillary ezivimba amanzi zifakwa ngaphansi kwezisekelo zemigwaqo noma izakhiwo.
8) Isetshenziselwa ukukhipha ungqimba oluyisisekelo ngaphansi kwenkundla yezemidlalo noma umgwaqo wezindiza, kanye nokukhipha ungqimba olungaphezulu lwamadwala nomhlabathi oveziwe.
