About Sustenta Heketua Rūma Horoi

Ko Sustenta he heketua wāhanga-rua e whai ana ki te whakahou i te mōhiotanga kaitiaki taiao. Ka whakatū i tētahi paerewa hou mō te tiaki wai mā te whakamahi i te 2.5 rīta (0.66 kārani) ia paheke, he iti ake i ngā heketua taiao o nāianei e taka ana i waenganui i te 3.5L ki te 4.8L. Ko tēnei e tohu ana i te whakahekenga o te whakamahi wai tae noa ki te 60 ōrau, he kōwhiringa tika mō te toitūtanga o ia rā, o ia rā. I te mōhio ki te hiranga o te tiaki wai me te mahi tika o te heketua, ka tuku a Sustenta i tētahi wheako heketua hou e āwhina ana hoki i te tiakitanga o tētahi o ngā rauemi matua o te ao.

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

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).
