Isishwankathelo seeDuctile Iron Pipes
Yenziwe ngentsimbi ethambileyo esetyenziswa kakhulu ekudluliseni nasekusasazeni amanzi amdaka, ehlala ixesha elide ngaphezu kweminyaka eli-100. Olu hlobo lombhobho luphuhliso oluthe ngqo lombhobho wentsimbi yangaphambili, oye wathatha indawo yawo. Ilungele ukufakwa phantsi komhlaba kwemigca ephambili yokuhambisa.
