Inethi yokudonsa amanzi ehlanganisiwe enezinhlangothi ezintathu iyinto evame ukusetshenziswa kumaphrojekthi amakhulu. Ngakho-ke, ingabe ingavimbela ukuthungwa kwenhlabathi?
I. Izakhiwo zezinto kanye nendlela yokulwa nodaka
Inethi yokukhipha amanzi ehlanganisiwe enezinhlangothi ezintathu yenziwe ngenethi yepulasitiki enezinhlangothi ezintathu ene-geotextile eboshiwe enezinhlangothi ezimbili, ngakho-ke ukusebenza kwayo kokukhipha amanzi kuhle kakhulu. Ingaphakathi layo liyi-geonet core enezinhlangothi ezintathu, equkethe ubambo oluqondile olujiyile kanye nobambo oluthambekele phezulu naphansi ukuze kwakheke umzila wokukhipha amanzi ophumelelayo. Izimbambo ezihlelwe ngokuphambana azigcini nje ngokuthuthukisa ukuzinza kwesakhiwo, kodwa futhi zivimbele i-geotextile ukuthi ingangeni emseleni wokukhipha amanzi, futhi zigcine ukusebenza kahle kokukhipha amanzi ngisho nangaphansi kwemithwalo ephezulu.
Ngakho-ke, ingakhipha amanzi ngokushesha ngesikhathi sokukhipha amanzi, futhi ingasebenzisa nomphumela wokulwa nokuhlunga kwe-geotextile ukuvimbela izinhlayiya zomhlabathi ukuthi zingangeni emgudwini wokukhipha amanzi, okungavimbela ukuthungwa kwenhlabathi. Inethi yokukhipha amanzi ehlanganisiwe enezinhlangothi ezintathu nayo inokumelana okuhle nokugqwala kanye nokumelana ne-asidi ne-alkali, ngakho-ke impilo yayo yenkonzo inde kakhulu.
II. Izibonelo zezimiso zokusebenza kanye nezindlela zokusebenzisa
Ezisetshenzisweni ezisebenzayo, inethi yokudonsa amanzi ehlanganisiwe enezinhlangothi ezintathu ingaxazulula izinkinga zokudonsa amanzi emigwaqweni, emigwaqweni, emihubheni nakwamanye amaphrojekthi ngokusebenzisa indlela yayo yokudonsa amanzi eyingqayizivele. Isibonelo, kumaphrojekthi omgwaqo, ukuyibeka ngaphansi kobuso bomgwaqo kungakhipha ngokushesha umswakama esakhiweni sobuso bomgwaqo futhi kuvimbele umswakama ukuthi ungene emgudwini womgwaqo, okubangela ukuthi umgudwi uthambe noma wonakalise. Umphumela wayo wokulwa nokuhlunga ungavimbela nezinhlayiya zomhlabathi ezisemagudwini ukuthi zingangeni ohlelweni lokudonsa amanzi futhi kugcine umsele wokudonsa amanzi ungaphazanyiswa.
Ezindaweni zokulahla udoti, ayikwazi ukusebenza nje kuphela njengesendlalelo sokukhipha amanzi angaphansi komhlaba ukuze ikhiphe ngokushesha amanzi angaphansi komhlaba endaweni yokulahla udoti, kodwa futhi njengesendlalelo sokuqoqa amanzi angcolile kanye nesendlalelo sokukhipha amanzi angcolile ukuze iqoqe futhi ikhiphe amanzi angcolile akhiqizwa ngesikhathi senqubo yokulahla udoti. Kule nqubo, ukusetshenziswa kwayo okuhlanganisiwe nama-geotextiles angalukiwe kungathuthukisa ikhono layo lokulwa nokuvaleka, kuqinisekiswe ukukhishwa okuhlelekile kwe-leachate, futhi kugweme ukungcola kwemvelo okubangelwa ukuvaleka.
Njengoba kungabonakala kulokhu okungenhla, inetha lokukhipha amanzi elihlanganisiwe elinezinhlangothi ezintathu lingavimbela ukuvaleka. Alikwazi nje ukuxazulula izinkinga zokukhipha amanzi emigwaqweni, emigwaqweni, emihubheni nakwamanye amaphrojekthi, kodwa futhi lidlala indima ebalulekile ezindaweni ezikhethekile njengezindawo zokulahla udoti.
