Ezindaweni zasemakhaya, abaningi abafakiwe kunethiwekhi yokuhambisa indle ngenxa yezinkinga zendawo, ezomnotho nezobuchwepheshe. Lokhu kusho ukuthi ukwelashwa kwamanzi asekhaya kulezi zindawo kudinga indlela ehlukile kunasemadolobheni.
Ezindaweni zobunikazi, izinhlelo zokwelashwa kwemvelo ziyindlela ejwayelekile yokwelapha amanzi angcolile. Le ndlela isebenzisa amandla okuhlanza wemvelo wenhlabathi, izitshalo kanye nezinto eziphilayo ezincane ukwelapha amanzi amdaka asekhaya. Izibonelo zifaka amaxhaphozi, amachibi nezinhlelo zokwelashwa komhlaba. Lezi zinhlelo zivame ukwethula amanzi asekhaya angcolile endaweni ethile futhi ahlanze amanzi amdaka ngokusebenzisa isenzo senhlabathi esinothile nesitshalo, kanye nesenzo sokonakala kwezinto ezincane. Izinzuzo zale ndlela ukuthi kunezindleko eziphansi, kulula ukulondolozwa kanye nemvelo enobungane. Kodwa-ke, inobubi bokusebenza kahle kokwelashwa okuphansi futhi idinga indawo enkulu yomhlaba.
Kwamanye amalokishini amakhulu, noma izindawo zokuhlala ezigxile kakhulu, zingakhiwa izitshalo zamanzi aphakathi nendawo angcolile. Lolu hlobo lwesitshalo sokwelashwa luvame ukugxila endle yasekhaya kusuka komakhelwane bese uthatha indlela evamile yomzimba, yamakhemikhali kanye neyokuzalwa. I-effaent ephethwe imvamisa ivame ukungabulali, okuphikisayo nangokuphamba, futhi yadedelwa ngemuva kokuhlangabezana nezindinganiso zokuphuma. Izinzuzo zalolu hlobo lokwelashwa ukuthi linamandla amakhulu okulashwa kanye nokusebenza kahle kakhulu; Okubi ukuthi kudinga inani elikhulu lezinhlokodolobha kanye nezinsizakusebenza ezizotshalwa ekwakhiweni nasekusebenzeni kwalo.
Ngaphandle kwezindlela ezingokomzimba nezobunjiniyela okukhulunywe ngazo ngenhla, uhulumeni futhi udlala indima ebalulekile ekwelapheni indle yendle yasemalokishini. Uhulumeni angahola izakhamizi namabhizinisi ukuthi anake kakhulu ukwelashwa kwendle nokuvikelwa kwemvelo ngokwakha izinqubomgomo ezifanele, njengezindleko zokuhambisa indle kanye nezinkuthazo zokuvikela ezemvelo. Ngasikhathi sinye, ngezemfundo nangomphakathi, ukukhulisa ukuqwashisa kwabahlali ngokuvikelwa kwemvelo, ukuze bakwazi ukubamba iqhaza ngenqubo yokwelashwa kwendle ezifuywayo.
Kwamanye amalokishini athuthuke kakhulu, imishini yokwelashwa yendle ekhaya nayo iyindlela ejwayelekile. Lolu hlobo lwemishini luvame ukufakwa egcekeni noma eduze komndeni ngamunye, futhi lungasetshenziselwa ukwelapha indle yasekhaya ekhiqizwa indle ekhiqizwa ngumndeni e-SITU. Imishini inezinto eziningi zangaphakathi ezifana nokuhlunga ngokomzimba, ukusabela kwamakhemikhali kanye ne-biodegradation, okungasusa izinto eziphilayo, i-nitrogen, phosphorus nezinye izinto ezivela emanzini amdaka zasekhaya. Inzuzo yalolu hlobo lwemishini ukuthi iyavumelana nezimo futhi ilula, futhi ingafakwa futhi isetshenziswe noma kuphi nganoma yisiphi isikhathi.
Ngamafuphi, ukwelashwa kwendle ezifuywayo ezindaweni zasemalokishini kungafakwanga kunethiwekhi yokuthuthwa kwendle kuyinkinga ephelele edinga inhlanganisela yezindlela ezahlukahlukene zokwelashwa. Ekukhetheni imishini yokwelashwa kwamanzi okuhlangene ngamalokishini, ukuvikelwa kwezemvelo ukuhlinzeka ngezixazululo nemishini ngokwezidingo ezahlukahlukene nezimo zangempela.
