Emkhakheni wokwakha, imikhiqizo ye-Arex inezinzuzo eziyingqayizivele. Ohlelweni lokuxhuma amapayipi, ithimba lethu lobuchwepheshe lingenza ngcono izinto zamapayipi ngokwesimo sangempela samakhasimende, lihlose imidiya ehlukahlukene yokujikeleza, isibonelo, ngemikhiqizo yokuxhumanisa insimbi, singangeza ishubhu yerabha noma yepulasitiki odongeni lwangaphakathi ngokwendlela ejikelezayo, ukugwema ukuthi izingxenye zensimbi zigqwale uketshezi ngqo. I-Arex isebenzisa imikhiqizo yezinto zensimbi nezingezona ezensimbi ezihlanganisiwe ukuze zisebenzise ngokugcwele izici zezinto ezahlukene, ukukhiqiza umkhiqizo ohlanganisiwe onezimpawu eziningi. Kuyo yonke inqubo yokwakha, kungaba ukuthuthwa nokucubungula isihlabathi namatshe esigabeni sokuqala noma ukwengezwa kohlelo lwamapayipi esigabeni esiphakathi nesokugcina, imikhiqizo enezimpawu ezihlanganisiwe zezinto zensimbi nerabha-plastiki ingabonakala yonke indawo. Ngokuthuthuka nokujula komkhakha wokwakha, sikholelwa ukuthi imikhiqizo ye-Arex inganikeza amakhasimende amaningi isengezo esibalulekile emsebenzini womkhakha. Amakhasimende angenza ngezifiso futhi aklame imikhiqizo ngokwezidingo zawo. I-Arex izohlinzeka ngosekelo lobuchwepheshe oludingekayo kanye nensizakalo yeqembu kumakhasimende adinga usizo.
