Ngokusho kokuhlangenwe nakho kuka-Teyu S&A, amayunithi okupholisa amanzi alebula imishini yokusika i-laser anenkinga yokucindezela okuphansi kwesiqandisi, ikakhulukazi ngenxa:
1.Iswishi elawula isiqandisi iyaphuka;2.Iyunithi ye-water chiller iyavuza isiqandisi.
Esimeni sokuqala, kuphakanyiswa ukuthi kuthunyelwe iyunithi yokupholisa amanzi lapho ikhiqizwa khona.
Esimeni sesibili, kuphakanyiswa ukuthi kutholwe futhi kushiselwe indawo evuzayo noma uxhumane nomhlinzeki weyunithi ye-water chiller ukuze isiqandisi sigcwaliswe kabusha.
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.
