Inkqubo inokunciphisa i-pH yamanzi kunye nokunciphisa i-turbidity ukuvumela ukukhululwa okukhuselekileyo kubuyele kwindawo. Inokunyuka iye kuthi ga kwi-88gpm, okanye malunga neelitha ezingama-5,238 (i-20 cubic metres) ngeyure.
Ukongeza kwinkqubo ye-Aquajet ye-EcoClear kunye ne-710V, i-spray yamanzi kunye nenkonzo ye-vacuum iphinda isebenzise i-boom kunye necandelo elongezelelweyo le-tower ukwandisa uluhlu lwe-robot ye-Hydrodemolition ukuya kwii-40 ezinyaweni. Iinkonzo zokutshiza zamanzi kunye ne-vacuum zincoma ukusebenzisa i-EcoClear njengenxalenye yenkqubo ye-loop evaliweyo ukujikeleza amanzi emva kwe-Aqua Cutter 710V yayo. Oku kuya kuba kukuqala kwenkampani ukusebenzisa i-EcoClear ukubuyisela amanzi kwisikali esikhulu kangaka, kodwa uLavoie neqela lakhe bakholelwa ukuba i-EcoClear kunye ne-710V iya kuba yindibaniselwano efanelekileyo kwizicelo ezicela umngeni. "Le projekthi ivavanye abasebenzi kunye nezixhobo zethu," utshilo uLavoy. "Kukho ezininzi zokuqala, kodwa siyazi ukuba sinamava kunye nenkxaso yeqela le-Aquajet ukuguqula izicwangciso zethu ukusuka kwithiyori ukuya kwinyani."
I-spray yamanzi kunye nenkonzo yokucoca ifike kwindawo yokwakha ngo-Matshi 2018. Ubushushu obuphakathi ngu-20º F (-29º Celsius), ngamanye amaxesha buphantsi -40º F (-40º Celsius), ngoko ke inkqubo yokugcinwa kunye ne-heater kufuneka imiselwe ukubonelela indawo yokukhusela malunga nendawo yokudiliza kunye nokugcina impompo isebenza. Ngaphandle kwenkqubo ye-EcoClear kunye ne-710V, ikontraki iphinde isebenzise i-boom kunye necandelo elongezelelweyo le-tower ukunyusa uluhlu olusebenzayo lwe-robot ye-Hydrodemolition ukusuka kwinqanaba le-23 ukuya kwii-40 ezinyaweni. Ikhithi yolwandiso ikwavumela iikontraka ukuba zenze i-12-foot cuts ububanzi. Ezi zongezelelo zinciphisa kakhulu ixesha lokuphumla elifunekayo ekubekweni ngokutsha rhoqo. Ukongeza, isitshizi samanzi kunye neenkonzo zevacuum zisebenzisa amacandelo ezongezelelweyo zemipu yokutshiza ukwandisa ukusebenza kakuhle kunye nokuvumela ubunzulu obuziimitha ezisibhozo ezifunekayo kwiprojekthi.
Isitshizi samanzi kunye nenkonzo yokucoca idala i-loop evaliweyo ngenkqubo ye-EcoClear kunye neetanki ezimbini ze-21,000 zegaloni ukubonelela ngamanzi kwi-Aqua Cutter 710V. Ngethuba le projekthi, i-EcoClear icutshungulwe ngaphezu kwe-1.3 yezigidi zeelitha zamanzi. Iinkqubo ze-Aquajet zase-USA
USteve Ouellette ungumlawuli oyintloko wenkampani yenkonzo yesitshizi samanzi kunye ne-vacuum, ojongene nenkqubo ye-loop evaliweyo yeetanki ezimbini ze-21,000 zegaloni ezibonelela ngamanzi kwi-Aqua Cutter 710V. Amanzi amdaka aqondiswe kwindawo ephantsi aze ampompelwe kwi-EcoClear. Emva kokuba amanzi elungisiwe, aphinda ampontshelwe kwitanki yokugcina ukuze aphinde asetyenziswe. Ngexesha leshifti yeeyure ezili-12, isitshizi samanzi kunye nenkonzo yokucoca isuse umyinge we-141 cubic feet (4 cubic metres) yekonkile kwaye yasebenzisa malunga neelitha ezingama-40,000 zamanzi. Phakathi kwabo, malunga ne-20% yamanzi alahlekileyo ngenxa yokunyuka kwamanzi kunye nokufakwa kwikhonkrithi ngexesha lenkqubo ye-Hydrodemolition. Nangona kunjalo, iinkonzo zokutshiza ngamanzi kunye ne-vacuum zingasebenzisa inkqubo ye-EcoClear ukuqokelela nokuhlaziya i-80% eseleyo (iigaloni ezingama-32,000). Ngexesha leprojekthi yonke, i-EcoClear iqhube ngaphezu kwe-1.3 yezigidi zeelitha zamanzi.
Isitshizi samanzi kunye neqela lenkonzo yokucoca i-Aqua Cutter malunga neshifti yeeyure ezili-12 yonke imihla, isebenza kwicandelo le-12-foot-wide-wide section ukudiliza ngokuyinxenye i-30-foot-high pier. I-Aquajet Systems 'Inkonzo yokutshiza yamanzi yaseMelika kunye nenkonzo yokucoca kunye nabasebenzi bolawulo lweprojekthi badibanisa ukuchithwa kwishedyuli enzima yeprojekthi yonke, ukugqiba umsebenzi kwisigaba esingaphezu kweeveki ezimbini. U-Lavoie kunye neqela lakhe basebenza i-Aqua Cutter phantse yonke i-12-iyure shift yonke imihla, esebenza kwicandelo le-12-foot-wide-wide section ukudiliza ngokupheleleyo udonga. Umsebenzi owahlukileyo uya kuza ebusuku ukuze asuse imivalo yentsimbi kunye nobutyobo. Inkqubo yaphindwa malunga neentsuku ezingama-41 zokuqhushumba kunye neentsuku ezingama-53 zokuqhushumba kwindawo.
