The CBT is the only portable, self-contained, household level water quality test that detects and quantifies E. coli levels in the World Health Organization 100mL standard sample, requires no electricity or lab, provides built-in decontamination and requires no incubator at temperatures above 25 degrees Celsius. It eliminates costs for refrigeration, sample transportation, lab sample analysis and processing and highly trained, specialized technicians.
Compact and self-contained, the CBT provides microbial water testing in a few simple steps with easy-to-score, visual, color change results.
The CBT has many benefits for water, sanitation and hygiene programs:
+ Provides quantitative water quality results based on the World Health Organization’s risk categories
+ Enables water quality testing even in low resource and disaster settings
+ Allows individuals and communities to make informed decisions about the safety of their drinking water and actions needed to improve water quality
+ Eliminates costs for refrigeration, sample transportation, lab sample analysis and processing, and highly trained, specialized technicians
+ Removes indirect costs associated with other water testing products such as labor costs that address product requirements, recleaning and sterilization of reusable testing components, required supporting equipment and excessive test waste
+ Expands and improves efficiency of water testing programs
Testing water quality is an essential component of any water, sanitation and hygiene program. The CBT now makes it possible for anyone, in any location or environment, to detect fecal bacteria in drinking water, determine if their water is safe to drink and monitor water quality.
Dr. Mark Sobsey , the creator of the CBT, is an authority on water quality and a distinguished professor at the University of North Carolina Gillings School of Global Public Health. “It’s impossible to tell if water poses a health risk just by looking at it,” says Sobsey. “Drinking water has to be tested and monitored on an ongoing basis to insure continued safety. In developing countries and rural areas, the ability for local authorities and inhabitants to test water is severely limited. Yet a day without safe water is a day of being at risk of waterborne disease.
“Drinking water quality test kits should be accessible and easy to use, so that people can be informed and empowered to take appropriate action when their drinking water poses a risk to their health.”
Already used throughout the world, the CBT provides quantitative drinking water quality test results based on the World Health Organization risk categories and country standards. The CBT has been tested extensively by third parties against other standard testing methods and provides results on par with more complicated, expensive and less portable tests.

Why Water and Integrity? Webinar #6
|Date and time:||April 25, 1300 GMT (Click here to see what time that would be where you live)|
|Speaker:||Binayak Das, Water Integrity Network|
|Click here to enter the webinar|
|Description:||Water will determine what world the future generations will live in. But this precious resource is underpinned by bad governance and lack of integrity. In many countries shortcomings are not due to shortage of water resources but due to governance failures, such as institutional fragmentation, lack of coordinated decision-making, corruption and low levels of transparency and accountability. The result is that governance systems are often not able to prevent or even provide incentives for unethical behaviour and poor professional practice. Corruption is moreover all pervasive and affects all aspects of the water sector – from water resources management to drinking water services, irrigation and hydropower, it occurs in all phases – from design through construction to operation and maintenance – and it is a major factor in the global water crisis. Integrity issues are often at the core of conflicts around water, which are arising at local, country and international levels.Improving water governance requires transparency, accountability and fighting corruption. It requires the right knowledge, access to strong partnerships and good tools. Improving water integrity means working with preventive measures to promote transparency, accountability and participation in water. Lessons have already been learnt from this preventive work.|
|About the speaker:||Binayak Das is the Programme Coordinator for Knowledge Management and Action Research at the Water Integrity network and also is focal point for South Asia. He has been associated with the water sector for the past 13 years – as a journalist, writer, researcher, coordinator and consultant.The Water Integrity Network (WIN) was formed in 2006 to respond to increasing concerns among water and anti-corruption stakeholders over corruption in the water sector. It combines global advocacy, regional networks and local action, to promote increased transparency and integrity, bringing together partners and members from the public and private sectors, civil society and academia, to drive change that will improve the lives of people who need it most.|
|About the Webinars: Web-based Seminars||They are presentations or lectures transmitted over the Web. With support from IFAD, TheWaterChannel started a series of Webinars on a variety of topics under three themes related to rural poverty alleviation. The Webinars will be organised together with our partners UNESCO-IHE and Cap-Net, and will feature some well-known experts on these topics. The Webinars will be collaborative; the participants will be able to communicate with the resource persons in real-time. Apart from lectures, there will be key resources, polls and question-answer sessions.|

The talk is titled: Wastewater, a resource or a weapon of mass destruction?
Valérie shows us how to turn recycled wastewater into a commoditized resource, improve water sanitation, provide efficient water usage, and reduce price volatility.
Valérie Issumo is the CEO of Prana Sustainable Water company (http://www.pranasustainablewater.ch) . An economist, she worked for 15 years as a soft commodities trader and as a trainer in Belgium, Uruguay, Cameroon and Switzerland. Throughout her career she has fought for sustainability and risk mitigation in the entire value chain of traded goods. She is a university lecturer and also a consultant for food security, socially responsible investments, pricing ecosystems and the assessment of water interdependencies. Valérie holds an MBA, has studied at various international water centres, and was a recipient of the Prize of the Belgian Minister of Foreign Trade.
Prana Sustainable Water is acting for the following challenges:
- Reducing the 80% untreated wastewater (UNEP) by matching offers and pre-paid demands of treated water allowing to finance sanitation and restore the public water quality as common good for not hindering growth and strategies.
- Water is the underlying commodity of every goods or services: please check www.cdproject.net/water and www.waterfootprint.org: : Prana Sustainable Water has designed Ethical Water Titles© – futures contracts – to commoditize treated wastewater as tradable resource on the Ethical Water Exchange platform or commodities exchange for water procurement and price security.
- Scaling-up clean technologies for wastewater:the members of Prana Sustainable Water Club active in wastewater can benefit organized markets through solvent demands of recycled water via Ethical Water Titles© allowing to leapfrog the leverage effects solving simultaneously water, health, economic, environmental and social issues.
- Offset water consumption : wastewater can be recycled on an infinite basis. Prana Sustainable Water boosts responsible productions or services prioritizing reuse water with the automatic respect of the Water Exploitation Index growingblue.com and storing part of recycled wastewater into green water bnks© for philanthropy, reforestation and production of green/rain water, energy, public services like fires..etc…
- Defense and food security Our motto is to incentivize responsible water use to produce:
– what makes sense (prioritizing commoditized recycled water from wastewater for Human Rights, for water footprints of functional food or with high nutritional value and ecosystems services),
– where it makes sense (according to the impact),
– how it makes sense (with treated wastewater and sludge energy).

Waterless Urinals do not require water for flushing and can be promoted at homes, institutions and public places to save water, energy and to harvest urine as a resource. Reduction in infrastructure required for water supply and waste water treatment is also a spinoff arising from installing waterless urinals. The concept, founded on the principles of ecological sanitation helps in preventing environmental damage caused by conventional flush sanitation systems.
In recent years, Human Urine has been identified as a potential resource that can be beneficially used for agriculture and industrial purposes. Human urine contains significant portion of essential plant nutrients such as nitrogen, phosphate and potassium excreted by human beings. Urine and faeces can also be separated employing systems such as urine diverting toilets. In the light of diminishing world’s phosphate and oil reserves which determine availability as well as pricing of mineral fertilisers, harvesting urine for reuse in agriculture assumes significant importance. Akin to the movement for harvesting rain water, urine harvesting is a concept which could have huge implications for resource conservation.
