About Sustenta 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.

The Recognition

About the Umklomelo Wesiliva we-A' Design Award

Sustenta Ithoyilethi Yegumbi Lokugezela iwinile uMklomelo Wesiliva we-A' Design Award, ukwaziswa okuhloniphekile ngokungajwayelekile okunikezwa imiklamo esezingeni eliphezulu, ebukekayo nethinta kakhulu. Abawinile beSiliva yimisebenzi egqamile kakhulu nedala kakhulu ebonisa ubungcweti obuphawulekayo, italente nobuhlakani babaklami babo. Sustenta Ithoyilethi Yegumbi Lokugezela ilindeleke ukuba ibe ngumsebenzi omuhle wesibonelo, onobungcweti obuphawulekayo nezinto ezintsha ezijulile. Lo mklamo owinile uMklomelo Wesiliva we-A' Design Award uyinto entsha ebonakala kakhulu nethakazelisayo esiza futhi isunduza imingcele yobuciko, isayensi, ukuklama nobuchwepheshe. Sustenta Ithoyilethi Yegumbi Lokugezela iyinto enomhawu omkhulu kuyo evusa izifiso, ilethe imizwa emihle futhi ivuse ukumangala nokuxakeka.

Behind the Design

Credits, team members and technical details provided by the designer.

Unique Properties: Sustenta uses only 2.5 liters (0.66 gallons) per flush, its performance is well below the consumption that is considered "ecologic" (3.5 and 4.8 lpd),which represents a saving of 60% of water. Water preservation is crucial, but so it is to keep the toilet efficiency at its most, so users can enjoy a high quality product and preserve our vital liquid at the same time. It was specially designed to enhance the water flushing force to maintain a total dragging and cleaning performance. Developed and tested to successfully comply ASME standards.
Dimensions & Packaging: Product: 342 mm x 701 mm x 811 mm
Package 1: 660mm x 760 mm x 422 mm
Package 2: 360 mm x 180 mm x 425 mm
Tags: sustenta, water saving toilet, 2.5 liters per flush, sustainable toilet, 0.66 gallons per flush
Production Technology: High quality vitreous China ceramicware, produced by molding. The toilet´s basin and trap are (like the rest of the main body) enameled to ensure a top notch performance. The shape of this product is based on efficent costs of production, so that it can be bought by almost anyone (280 euros - 260 USD) it uses the principle of gravity for its performance and several fluid dynamics analysis were conducted to establish the correct shape that allowed us to perform at low pressures and 2.5 liters per flush of water consumption.
Design Challenge: The hardest part of this project was to define, test and ensure the flushing quality with the lesser amount of water possible by running numerous fluid dynamics tests and make the pertinent changes to the physical / aesthetic design. Its shape answers to the premise of making a product cost efficient and with the less amount of scrap possible
Research: Sustenta uses only 2.5 liters (0.66 gallons) per flush, its performance is well below the consumption that is considered "ecologic" (3.5 and 4.8 lpf),which represents a saving of 60% of water, having the highest water saving rate in the world. Its aimed to be sold in residential, institutional and public markets due to its working pressure rate (0.2 - 6 bar). It can save up to 88.2 liters per day (32,000 liters per year) for an average house use of 7 times per day. Saving up to 1,191,141 Mega Liters / year in Mexico alone.
Some of the crucial tests ran in a certified laboratory to ensure the quality and water saving rate were:
ASME A112.19.2-2018/CSA B45.1-18 tested/evaluated:
Gravity flush tanks
Water Consumption Rate
Drain line test (18 meters)
Waste extraction test
Granule and ball test
Inspiration: Inspired in contemporary and metropolitan design, it has sleek, well defined surfaces made possible thanks to the highest quality in vitreous ceramics with long lasting brightness. Its shape was defined by production process to ensure the minimum quantity of scrap and a maximum quality efficiency regarding molding, casting, etc.
Project Duration: The project started in January and finished in December 2023 in Mexico City, it was launched on mid December 2023.
Operation Flow: Sustenta creates a vortex which enhances the flushing force through the ceramic basin and trap in order to drag the waste efficiently, maximizing its performance, this keeps the basin clean and overall the whole toilet. It complies with the ASME standard tests, taking away efficiently 400gr of organic waste, with an overall dragging distance of 14m. Its best feature is the water saving rate, but also its working pressure, allowing Sustenta to fully function at low and high pressures (from 0.2 to 6 bar).
