Ithoyilethi Yegumbi Lokugezela I-Sustenta iyithoyilethi eneziqa ezimbili ehlose ukuchaza kabusha ukuqaphela imvelo. Imisa izinga elisha ekulondolozeni amanzi ngokusebenzisa amalitha angu-2.5 (amagaloni angu-0.66) ngokugcwala kanye, okungaphansi kunamathoyilethi anemvelo amanje asukela ku-3.5L kuya ku-4.8L. Lokhu kumele ukuncipha okufinyelela kumaphesenti angama-60 ekusetshenzisweni kwamanzi, okufaka inketho enzuzo yokusimama kwansuku zonke. Ngokuqaphela ukubaluleka kokulondoloza amanzi nokusebenza kwethoyilethi, i-Sustenta iletha isipiliyoni esisha sethoyilethi esiphinde sinomthelela ekulondolozeni omunye wemithombo ebalulekile yomhlaba.
