Kuyilo lwendawo yokuhlala yoluntu, ikhitshi yenxalenye enkulu, indlu yangasese ayibeki umgangatho wokukhupha amanzi.Ezinye ziimfuno zeyunithi yokwakha, kwaye ezinye ziingcamango zabayili.Izizathu zishwankathelwa zibe zithathu:
(1) umbhobho womgangatho ukhupha ivumba elibi kwigumbi;
(2) umdibaniso wombhobho womgangatho kunye nomgangatho kulula ukuvuza, ukwandisa umsebenzi wokulondoloza;
(3) Ufakelo lombhobho womgangatho wokuhambisa amanzi kwandisa iindleko zeprojekthi.
Enyanisweni, indlela ikhitshi, indlu yangasese engawubeki ngayo umjelo womgangatho ayinqweneleki.Nangona kubonakala ngathi i-drain yomgangatho incinci, kodwa indima yayo ebalulekileyo kubomi bemihla ngemihla yaBantu ayinakuhoywa.Nokuba umgangatho wokuhambisa amanzi ekhitshini nakwindlu yangasese usetiwe okanye awukho kuya kuchaphazela ngqo ubomi obutofotofo babantu, kwaye ngamanye amaxesha kude kuphazamise ubomi obuqhelekileyo babantu.
