Umehluko omkhulu kakhulu phakathi S&A Teyu umshini wokushibilika wamanzi okushisa okukabili we-Teyu kanye nomshini wokushisa wamanzi wokushisa owodwa ukuthi amamodeli okushisa akabili aneluphu yamanzi ejikeleza kabili kuyilapho amamodeli okushisa okukodwa aneluphu eyodwa yamanzi omjikelezo. Emishinini S&A ye-Teyu ye-Teyu ekabili izinga lokushisa lokushisa kwamanzi, ingapholisa umzimba we-laser nesixhumi se-QBH ngesikhathi esifanayo, ehlise kakhulu amanzi ajiyile futhi ivikele i-laser.
Mayelana nokukhiqizwa, i- S&A I-Teyu itshale izimali zokukhiqiza ezingaphezu kwesigidi samayuan, iqinisekisa ikhwalithi yochungechunge lwezinqubo kusukela ezingxenyeni eziyinhloko (i-condenser) ye-chiller yezimboni kuya ekushiseleni kweshidi lensimbi; ngokuphathelene nempahla, S&A I-Teyu imise izindawo zokugcina izimpahla emadolobheni amakhulu aseShayina, inciphise kakhulu umonakalo ngenxa yokuhanjiswa kwezimpahla ezikude, kanye nokusebenza kahle kwezokuthutha; mayelana nesevisi yangemuva kokuthengisa, isikhathi sewaranti iminyaka emibili.
