Yiziphi izinzuzo kanye nobubi bokumbiwa kwemigodi evulekile uma kuqhathaniswa nokumbiwa kwemithombo?
I-1.Izinzuzo: Imayini inamandla amakhulu okukhiqiza, ukukhiqiza okuphezulu kwabasebenzi, izindleko eziphansi, ukuphepha okuphezulu, izimo ezinhle zokusebenza, ukwakhiwa okusheshayo, nokusetshenziswa okuncane kwezinkuni, ikakhulukazi uma usebenzisa ukuhamba ngemoto.
2.Ukungalungi: Ukujula kwezimayini zomgodi ovulekile kunqunyelwe isilinganiso sokuhlubula, indawo yezwe inkulu, futhi inomthelela omkhulu emvelweni.Umthelela wesimo sezulu wenza ukukhiqizwa kwemayini emigodini evulekile kube yisizini futhi kunciphisa ukusebenza kahle kokukhiqiza.Kudingeka ukwethula imishini emikhulu, ukutshalwa kwezimali okukhulu

Yiziphi izinto ezibalulekile okumele zicatshangelwe ekunqumeni uhlelo lokuthutha emayini yomgodi ovulekile?
1) Ibanga lezimayini zemigodi evulekile, ikakhulukazi ubude betshe lensimbi, kufanele libe lifushane;
2) Lwela ukulungisa umugqa, noma ukuhambisa kube mncane ngangokunokwenzeka;
3) Zama ukusebenzisa imodi eyodwa yezokuthutha kanye nemishini;
4) Izinto zokuthutha kufanele zihambisane nempahla yezimayini;
5) Izinto zokuhamba ezinokwethenjelwa kanye nesikhathi esifushane sokumiswa kwemishini emikhulu;
6) Ukuphepha kwezokuthutha kanye nezindleko eziphansi.

Ngesisekelo sokuthi isikali semayini nohlelo lwezimayini lungahlangabezana nezidingo, ingxenye yokuqala yezimayini kufanele ikhethwe ezindaweni lapho ubukhulu bomzimba wensimbi bukhulu kakhulu, izinga le-ore liphezulu, umthwalo omningi uzacile, inani lokuchithwa kwengqalasizinda lincane, futhi nobuchwepheshe bezimayini busesimeni esihle, ukuze kuncishiswe inani lemiklamo yengqalasizinda, kufinyezwe ukukhiqizwa nesikhathi sokukhiqiza, kuthuthukise izinzuzo zezomnotho zasekuqaleni zemayini. Umgomo oyinhloko wokuvimbela ukungena kwamanzi emayini , umsebenzi ongangeni manzi kufanele wenziwe ukuze kuvinjelwe inhlanganisela eyinhloko yokulwa nokukhipha yalezi zinyathelo ezilandelayo zokuvikela amanzi yilezi:
Izinyathelo ezingaphansi komhlaba ezingangeni manzi: 1) umsele ongenelayo 2) ukuphambukisa umfula 3) indawo yokugcina amanzi okusiza ezikhukhuleni 4) idamu lomfula.
Izinyathelo zokuvimbela amanzi ngaphansi komhlaba: 1) Ukumba ukuhlola amanzi, ukuze kube nokungabaza nokuhlola, ukuhlola kokuqala ngemva kokumba izimayini;2) Setha izindonga ezingangeni manzi namasango angangeni manzi;3) Beka izinsika ezingangeni manzi;4) Grouting anti-seepage amakhethini;Udonga oluqhubekayo.
