Amanzi awumthombo wempilo kanye nensiza ebalulekile yokuthuthukiswa kwamadolobha.Nokho, njengoba kudlondlobala ukukhula kwamadolobha, ukushoda kwemithombo yamanzi nezinkinga zokungcola kuya ngokuya kugqama.Ukuthuthukiswa kwamadolobha okusheshayo kuletha izinselelo ezinkulu endaweni yemvelo kanye nentuthuko esimeme yamadolobha.Indlela yokwenza indle "ukuvuselelwa" bese ukuxazulula ukushoda kwamanzi emadolobheni, sekuyinkinga ephuthumayo okufanele ixazululwe.
Eminyakeni yamuva nje, emhlabeni wonke jikelele uguqule umqondo wokusetshenziswa kwamanzi, andise isikali sokusetshenziswa kwamanzi agaywe kabusha futhi andise ukusetshenziswa kwamanzi agaywe kabusha.Ngokunciphisa inani lamanzi ahlanzekile athathwayo kanye nendle ngaphandle kwedolobha ukuze kugqugquzelwe ukongiwa kwamanzi, ukulawula ukungcoliswa, ukunciphisa ukungcola kanye nokukhuthazana.Ngokwezibalo zokuqala zoMnyango Wezezindlu Nokuthuthukiswa Kwezindawo Zasemadolobheni-Makhaya, ngo-2022, ukusetshenziswa kwamanzi asemadolobheni asemadolobheni kuzwelonke kuzofinyelela ku-cubic metres eyizigidi eziyizinkulungwane ezingu-18, okuphindwe izikhathi ezingu-4.6 ngaphezu kweminyaka eyi-10 edlule.
Amanzi abuyiselwe amanzi ahlanzwe ukuze ahlangabezane nezindinganiso ezithile zekhwalithi kanye nezidingo zokusebenzisa.Ukusetshenziswa kwamanzi abuyiselwe kubhekisela ekusetshenzisweni kwamanzi abuyiselwe ukuchelelwa kwezolimo, ukupholisa kabusha okugaywe kabusha kwezimboni, uhlaza lwasemadolobheni, izakhiwo zomphakathi, ukuhlanzwa kwemigwaqo, ukugcwalisa amanzi emvelo kanye neminye imikhakha.Ukusetshenziswa kwamanzi agaywe kabusha akukwazi nje kuphela ukonga imithombo yamanzi ahlanzekile futhi kunciphise izindleko zokukhishwa kwamanzi, kodwa futhi kunciphisa inani lokuchithwa kwendle, kuthuthukise izinga lendawo yamanzi futhi kuthuthukise ikhono lamadolobha okumelana nezinhlekelele zemvelo ezifana nesomiso.
Ngaphezu kwalokho, amabhizinisi ezimboni ayakhuthazwa ukuthi asebenzise amanzi agaywe kabusha esikhundleni samanzi kampompi ukuze akhiqize ezimbonini ukuze akhuthaze ukugaywa kabusha kwamanzi ezimbonini nokuthuthukisa izinga nokusebenza kahle kwamabhizinisi.Isibonelo, iDolobha laseGaomi esiFundazweni saseShandong linamabhizinisi ezimboni angaphezu kuka-300 ngaphezu kwesikali, anenani elikhulu lokusebenzisa amanzi ezimbonini.Njengedolobha elinemithombo yamanzi eyivelakancane, iGaomi City ibambelele emcabangweni wokuthuthukiswa kohlaza eminyakeni yamuva futhi yakhuthaza amabhizinisi ezimboni ukuthi asebenzise amanzi agaywe kabusha esikhundleni samanzi kampompi ukuze akhiqize ezimbonini, nangokwakhiwa kwenqwaba yamaphrojekthi okuvuselela amanzi, amabhizinisi ezimboni zedolobha azuze izinga lokuphinda lisetshenziswe amanzi elingaphezu kwama-80%.
Ukusetshenziswa kabusha kwamanzi kuyindlela ephumelelayo yokuhlanza amanzi angcolile, okubalulekile ukuxazulula inkinga yokushoda kwamanzi emadolobheni nokukhuthaza ukuthuthukiswa kohlaza kwedolobha.Kufanele siphinde siqinise ukumenyezelwa nokukhuthazwa kokusetshenziswa kwamanzi agaywe kabusha ukuze kwakheke isimo senhlalo yokongiwa kwamanzi, ukongiwa kwamanzi nothando lwamanzi.
