Emalokishini ezindaweni, ngenxa yemikhawulo yendawo, ezomnotho nezobuchwepheshe, izindawo eziningi azifakiwe kunethiwekhi yokuthuthwa kwendle. Lokhu kusho ukuthi ukwelashwa kwendle ezifuywayo kulezi zindawo kudinga ukwemukela indlela ehlukile evela emadolobheni.
Ezindaweni zobunikazi, uhlelo lokwelashwa kwemvelo luyindlela evamile yokwelashwa kwendle. Le ndlela isebenzisa umthamo wokuhlanza wemvelo wenhlabathi, izitshalo, kanye nama-microorganisms ukwelapha indle yasekhaya. Isibonelo, amaxhaphozi, amachibi nezinhlelo zokwelashwa komhlaba. Lezi zinhlelo zivame ukwethula indle yasekhaya endaweni ethile, isebenzisa ukumuncwa kanye nokuhlunga kwenhlabathi nezitshalo, kanye nokonakaliswa kwama-microorganisms. Izinzuzo zale ndlela zibiza kakhulu, ukulungiswa okulula, kanye nemvelo enobungane. Kepha ukungathandeki kwaso ukuthi ukusebenza kahle okusebenzayo kuphansi, futhi kudinga indawo enkulu yomhlaba.
Kwamanye amadolobha amakhulu, noma izindawo zokuhlala ezigxile kakhulu, kuzokwakhiwa izitshalo zokwelashwa okuphakathi nendawo. Izitshalo ezinjalo zokwelashwa zivame ukusunduza indle yasendlini endaweni eseduze bese ziqhuba ukwelashwa okunobumbano ngokomzimba, kwamakhemikhali kanye nezemvelo. Ukuthuthwa kwendle okuphethwe kuvame ukukhishwa ngokubulala amagciwane, ukususwa kwe-nitrogen, ukususwa kwe-phosphorus nezinye izixhumanisi, bese kukhishwa ngemuva kokufinyelela izindinganiso zokuphuma. Izinzuzo zalokhu kwelashwa zisebenza kahle kakhulu kanye nokutshalwa kwemali kwemali ekhokhelwa kanye nezinsizakusebenza zokwakha nokusebenza.
Ngaphezu kwezindlela ezingenhla zomzimba nezobunjiniyela, uhulumeni futhi udlala indima ebalulekile ekwelashweni kwendle ezifuywayo. Uhulumeni angahola izakhamizi namabhizinisi ukuthi anake kakhulu ukwelashwa kwendle nokuvikelwa kwemvelo ngokwakha izinqubomgomo ezifanele, njengezindleko zokuhambisa indle kanye nezinkuthazo zokuvikela ezemvelo. Ngasikhathi sinye, ngemfundo nangomphakathi, ukuthuthukisa ukuqwashisa kwabahlali ngokuvikelwa kwemvelo, ukuze bakwazi ukubamba iqhaza ngenqubo yokwelashwa kwendle ezifuywayo.
Kwamanye amadolobha athuthuke kakhulu, imishini yokwethulwa kwezindlu yokuthuthwa kwendle nayo iyisinqumo esivamile. Le mishini ivame ukufakwa ngaphakathi noma eduze kwegceke lomndeni ngamunye, futhi ingaba ukwelashwa kwendle kwasekhaya okukhiqizwe ngumndeni. Imishini ifakwe nge-filltration engokomzimba, ukusabela kwamakhemikhali kanye ne-biodegradation nezinye izixhumanisi, ezingasusa izinto eziphilayo, i-nitrogen, phosphorus nezinye izinto ekuthayiphaleni kwendle olwandle. Inzuzo yale divayisi iyavumelana nezimo futhi ilula, futhi ingafakwa futhi isetshenziswe noma kunini futhi noma kuphi.
Ukufingqa, ukwelashwa kwendle ezifuywayo okungafakiwe kwinethiwekhi yepayipi yendle kuyinkinga ebanzi, okudinga ukuhlanganiswa nezindlela ezahlukahlukene nobuchwepheshe. Ekukhetheni kwemishini yokwelashwa ehlanganisiwe yokuhlanza indle, ukuvikelwa kwemvelo ye-ding kunganikeza izixazululo nemishini ngokuya ngezidingo ezahlukahlukene kanye nemibandela yangempela.
