Ukuze kugcinwe iyunithi yomshini wokushisa amanzi isesimweni esihle, kuyadingeka kakhulu ukushintsha amanzi ajikelezayo njalo. Kunconywa ukusebenzisa amanzi ahlanzekile noma amanzi acwengekile njengamanzi ajikelezayo bese uwashintsha njalo (ngokuvamile njalo ezinyangeni ezi-3) ukuze kugwenywe ukuvaleka komzila wamanzi ojikelezayo ngenxa yokungcola okuningi futhi kugcinwe ukusebenza okuhle kokupholisa kweyunithi yomshini wokushisa amanzi.
Ngokuphathelene nokukhiqiza, i-S&A Teyu itshale imishini yokukhiqiza engaphezu kwesigidi esisodwa sama-RMB, iqinisekisa ikhwalithi yochungechunge lwezinqubo kusukela ezingxenyeni eziyinhloko (i-condenser) ye-industrial chiller kuya ekushiseni insimbi; ngokuphathelene nokuthutha, i-S&A Teyu isungule izindawo zokugcina impahla emadolobheni amakhulu aseShayina, njengoba inciphise kakhulu umonakalo ngenxa yokuthutha impahla ibanga elide, futhi ithuthukise ukusebenza kahle kwezokuthutha; ngokuphathelene nensizakalo yangemva kokuthengisa, isikhathi sewaranti siyiminyaka emibili.
