Trial Reservoir Success for Arumloo\u2019s Ultra-Low Flush Toilet\u00a0<\/b><\/h4>\n

Ultra-low flush toilet achieves water savings of over 70% at trial site in Botswana.<\/p>\n

Scarcity and limited resources leave 2.6 billion people without hygienic sanitation worldwide, heightening the risk of waterborne disease. Yet modern toilets, requiring 6-20 liters per flush, are inaccessible to those in deprived areas or lacking water systems.<\/p>\n

South African company Arumloo Pty Ltd<\/a> invented an ultra-low flush toilet that reliably clears waste using 2L of water per flush. Inspired by the vortex shape of the Arum Lily, the Arumloo\u2019s design also reduces the need for multiple flushes. The company participated in the Climate Change Trial Reservoir to demonstrate the Arumloo\u2019s performance and acceptance in a busy school in Botswana. Inadequate sanitation facilities at the school hindered learning, and toilet leaks and flushing significantly contributed to its water expenses.<\/p>\n

NextGen Waterfree Solution replaced 120 toilets with Arumloos at a Gaborone school. NextGen offered to implement the water saving installations at zero capital cost to the school. In turn, the school agreed to pay a portion of the money saved for two years, up to 50%.<\/p>\n

The trial results indicate the Arumloos produced a 71% water saving, far exceeding the target of 50% savings. Alongside the cost savings associated with water demand reduction, there is an annual carbon saving of 468kg CO\u2082e\/year.<\/p>\n

Benef\u00edcios da abordagem\/inova\u00e7\u00e3o<\/strong><\/p>\n

Significant water and cost savings:<\/strong> Before the trial the school\u2019s water use reached 2303kL\/month, with a water bill exceeding P200,000 (USD $14,870) per month. Following the ultra-low flush Arumloo\u2019s installation the toilets saved more than 270kL\/month.<\/p>\n

Leakage prevention:<\/strong> The school\u2019s previous sanitaryware was old and leaky. Sub-metering within the new Arumloo toilets confirmed no recorded leakage.<\/p>\n

Redu\u00e7\u00e3o das emiss\u00f5es de GEE:<\/strong> The Arumloos save the school 1171kL water annually, equivalent to a 585.5kWh energy saving. As 93% of Botswana\u2019s power is derived from non-renewable sources, this school alone saves 468kg CO\u2082e annually.<\/p>\n

Risk-free trial:<\/strong> Trial Reservoir loan funding provided an opportunity for Arumloo and NextGen Waterfree Solution to test the technology risk-free.<\/p>\n

Servi\u00e7os especializados envolvidos:<\/strong><\/h5>\n

Trial Design support<\/b>: We evaluate technology trial plans based on users\u2019 innovation frames.\u00a0 The Trial Reservoir specifically addresses key questions that the trial must answer.<\/span><\/p>\n

Trial validation<\/b>: We receive and assess the trial end report from the technology vendor. The<\/span> Reservat\u00f3rio de teste<\/span><\/a> specifically addresses key questions that the trial must answer.<\/span><\/p>\n

Due Diligence<\/b>: Isle has a robust process for helping stakeholders adopt innovative technologies and ensuring they are fit for purpose.<\/span><\/p>\n

Loan funding<\/b>: Isle facilitates negotiation with technology developers and end users to agree upon the trials\u2019 critical success factors and key performance indicators (KPIs). Loans are then released to the technology developers.<\/span><\/p>\n

Zero Risk Trial<\/b>: Should a trial not meet its KPIs, there is no obligation for the tech company to pay back the loan. Similarly, there is no obligation for the end user to make a purchase order; the Trial Reservoir assumes the risk.<\/span><\/p>\n

Investor Introductions<\/b>: Isle uses its extensive worldwide network to provide introductions to potential investors.<\/span><\/p>\n

Resultados:<\/strong><\/h5>\n

Water savings:<\/strong> The toilets produced a 71% water saving, far exceeding the trial\u2019s target of 50% savings.<\/p>\n

Nationwide expansion:<\/strong> The trial\u2019s success in reducing water demand and preventing leakage has attracted nationwide attention. Visits from schools and the Ministry of Education led to NextGen\u2019s appointment to install Arumloos in other schools and public buildings.<\/p>\n
