Nangona kunjalo, oku kunokuba yinkqubo ethatha amandla amaninzi, kwaye i-brine edibeneyo eshiywe emva kokukhutshwa kwetyuwa kufuneka iphathwe ngononophelo ukuze ingonakalisi indalo.

I-YANTAI JIETONG ikhethekileyo kuyilo, ukwenziwa komthamo ohlukeneyo koomatshini bokukhupha amanzi olwandle ngaphezulu kwe-20years. Iinjineli zobuchwephesha zobuchwephesha zinokwenza uyilo ngokwemfuno ethile yomthengi kunye nemeko yokwenyani yesayithi.
