Africa wide WASH technology review published

The WASHTech project has published a literature review [1] focusing on 14 technologies used in Africa in the water, sanitation and hygiene (WASH) sector.

Descriptions for each technology include a selection of interesting case studies, and an explanation as to whether the technology meets technical, financial, social and institutional success criteria.
Only two technologies met all four success criteria: hand dug wells and the India Mark II pump, and the latter only with the caveat that there was a functional maintenance system.

The least successful technology was the Playpump. Pending further research, jerry cans and the gulper were only found to meet one success criteria (technical success). Except for bio-additives to pit latrines and Playpumps, all other technologies were technically successful. The other success criteria were met by roughly half of the technologies.

Core issues that WASHTech plans to take up further include the appeal of inappropriate technologies like Playpumps and Lifestraws to naive donors, and ways to get government approval for low-cost, locally managed technologies like rope pumps, biosand filters, constructed rainwater harvesting jars, water jetting and tippy taps.

The aim of the WASHTech project (2011-2013) is to introduce a robust Technology Assessment Framework (TAF), with local partners in Burkina Faso, Ghana and Uganda, that will assess the potential of new innovative WASH technologies. WASHTech is co-funded under the 7th Framework Programme of the European Commission’s Africa research programme. To learn more go to washtechafrica.wordpress.com

Point-of-use treatment: Patel Grand Challenge launches with competition to create world’s first “Smart Pot”

The University of South Florida’s (USF) Patel School of Global Sustainability through its Center for Global Solutions launched the first Patel Grand Challenge at the International Water Association’s Development Congress in Malaysia on 21 November 2011. The challenge invites inventors in developing nations to create a low-cost and easy-to-use water purification device that could save millions from the perils of contaminated drinking water.

The challenge was issued by Dr. Kiran C. Patel during the congress’ opening ceremony to over 600 delegates from around the globe. (To access more details, conference photos, and press coverage go here)

The challenge welcomes pre-proposal submissions through March 2012. Five applicants will be shortlisted and awarded up to US$ 8,000. The five finalists will be invited to prepare full proposals that will be reviewed by an international panel of experts at a major event. The winning proposal will receive up to US$ 100,000.

Manual drilling: engineering students develop “Village Drill” for Tanzania

A team of engineering students from Brigham Young University (BYU) has developed a human-powered drill that can reach a depth of up to 75 metres at 10% to 20% the cost of a traditional motorized well rig. A prototype of the “Village Drill” cost around US$ 4,000 (excluding labour) to make in the USA.

The BYU students created the drill for a project in Tanzania run by WHOLives.org, a nonprofit based in South Jordan, Utah. The project is also co-sponsored by the Ira A. Fulton College of Engineering and Technology.

The drill can be operated by four people. Three spin the wheel that turns the drill bit (cutting tool), and the fourth lifts the bit up and down when necessary to punch through tough spots. A water pump system removes the dirt from the 15 cm-wide hole.

In May 2011, a drilling team was able to construct a 45 m well  with the patented “Village Drill” in 3 days in Magugu, Tanzania.

“Water SMS”: improving urban water services in Indonesia through crowd–sourced map data

Poor residents in Indonesian cities of Malang (East Java) and Makassar (South Sulawesi) will soon be using their mobile phones to report problems with their water and sanitation services like poor water quality or quantity, well failures, failure of tanker water supplies, and costs for tanker water. This will enable water providers to learn about and quickly respond to customer complaints.

The Pacific Institute has launched the 3-year WASH SMS Project (September 2010 – September 2013) through a three-year pilot funded by USAID Development Grants Program (DGP). The Institute is working with Indonesian partner PATTIRO (experience in Indonesia focused on improving public services, and strengthening government capacity), and technology partner Nexleaf (a leader in mobile phone use to collect environmental data).

Groundwater depletion Is detected from space

Scientists from the University of California have been using small variations in the Earth’s gravity to identify trouble spots around the globe where people are making unsustainable demands on groundwater, one of the planet’s main sources of fresh water.

They found problems in places as disparate as North Africa, northern India, northeastern China and the Sacramento-San Joaquin Valley in California.

University of California’s Center for Hydrologic Modeling has developed Grace, the Gravity Recovery and Climate Experiment, that uses twin satellites to produce precise data on gravitational variations. The results are “redefining the field of hydrology”. Grace detects changes in ice, snow and water storage, surface water, soil moisture and groundwater.

Making such data available may increase sensitivities

in arid regions where groundwater basins are often shared by unfriendly neighbors — India and Pakistan, Tunisia and Libya or Israel, Jordan, Lebanon, Syria and the Palestinian territories — that are prone to suspecting one another of excessive use of this shared resource.

Grace can only supply reliable data for very large aquifers.

In northern India, the use of data from Grace in a study on aquifer depletion has led to some resistance.

“When in a place like India you say, ‘We’re doing something that is unsustainable and needs to change,’ well, people resist change. Change is expensive.”

Gates Foundation awards grants for 26 sanitation technology projects

A reusable self-decontaminating sanitary napkin, a children’s latrine training mat and a latrine using urine to flush instead of water are among 26 sanitation technology projects that have been awarded Gates Foundation grants. The topics of the wining projects range from hygiene, to household  latrines, ecological sanitation, and wastewater/sludge treatment and reuse for fertiliser and energy.

On 28 April 2011, the Gates Foundation announced that 88 new global health projects received grants, each worth US$ 100,000, in the 6th round of the Grand Challenges Explorations initiative. Out of these 88 projects, there were 26 winners in the category “Create the Next Generation of Sanitation Technologies”. See the full list of 26 sanitation awards. Projects with demonstrated success in their initial phase of research have the opportunity to receive Phase II funding of up to US$ 1 million.

India, New Delhi: using Facebook and SMS to keep the city clean

With this photo on Facebook local resident Akshay Arora asks the Municipal Corporation of Delhi (MCD) to "kindly send some one and get it clean this Toilet/Urinal". One day later on 7 April 2011, MCD replied: "Your complaint reference no. is 02/0704/SP"

The Municipal Corporation of Delhi (MCD) launched its Facebook page in January 2011 and an integrated SMS service in March 2011 to enable public monitoring of garbage collection sites and public urinals/toilets in areas under its jurisdiction.The first experiences were positive as illustrated by the example of 22-year-old Piyush Goyal posted his complaint of garbage spilling over from the dump in his area.

On January 8, he clicked pictures of the seven dirty ones in South Delhi’s R K Puram area and posted them on Facebook. And the next day, he says, he saw the pictures of clean dhalaos uploaded by the MCD.

“There is lot of transparency through this way. The man who actually cleans it asked me why I uploaded the pictures. So the information is going from top to the bottom,” says Goyal.

MCD additional commissioner (engineering) Anshu Prakash added:

“This system is increasing transparency, fixing accountability and putting everything under public scrutiny. And none of us like to be ashamed in public. So people have started working at the bottom”.

Battling cholera with NFC RFID-tracked drinking water in Haiti

Deep Springs International (DSI), a non-profit organization based in Pennsylvania, USA, and Nokia Research Center (NRC), Palo Alto, California, are teaming up to ensure the supply of clean drinking water in Haiti with NFC (near field communication) technology.

DSI has been delivering water treatment systems (which essentially consist of a covered 19-liter bucket with a spigot at the bottom) and a locally manufactured chlorine solution it has labeled Gadyen Dlo (Creole for "water guardian") since 2007.. Photo: Michael Ritter, DSI

Water treatment kits are being provided to track chlorine levels in household drinking water using NFC-enabled cell phones. NRC provided the health workers with approximately 50 Nokia 6212 NFC-enabled phones while UPM RFID supplied UPM BullsEye™ NFC tags with NXP Mifare Ultralight chip. Joseph “Jofish” Kaye, Senior Research Scientist, NRC, initiated the project together with David Holstius, a student and Ph.D. candidate at the University of California, Berkeley’s School of Public Health, who developed the software application for mobile phones.

Families in the most rural areas in Haiti will have one water treatment kit consisting of a five-gallon (19 litre) plastic bucket with a lid and spigot. The RFID (radio-frequency identification) tags are attached to buckets for storing the treated drinking water and delivered to families together with a chlorine solution and written instructions for using the kit. When DSI’s water technicians visit their homes, they check whether they are using the kits properly and provide additional chlorine solutions. The technicians will read the tags using NFC cell phones loaded with software guiding them to ask relevant questions about the water being tested. They then send the data to DSI’s headquarters via SMS. The software application uses the Frontline SMS platform.

Akvopedia Sanitation portal – now in Spanish

Akvopedia_spanish.png

Through the invaluable support of our intern Niharika Joshi, our Sanitation Platform is now also available in Spanish. After we included the French version last year, this is another step on the road to making Akvopedia a true multi-language platform. We hope it will be useful to Spanish-speaking people around the world.

The new Spanish portal contains 54 detailed articles on a wide range of sanitation technologies. The material was adapted from the extremely useful Compendium of Sanitation Systems and Technologies (2008, Spanish version here), written by Elisabeth Tilley and colleagues of Sandec, the Department of Water and Sanitation in Developing Countries at eawag, the Swiss Federal Institute of Aquatic Science and Technology, Dübendorf, Switzerland. The authors eventually have plans to make that publication available in Swahili. I’ll look forward to that.

UK: Thames Water’s new “Tweet a leak” service proves popular

In December 2010, Thames Water requested its social-networking customers to start reporting details of burst or leaking pipes on Twitter.

The UK’s largest water and wastewater company urged customers to ‘tweet a leak’ to its Twitter profile @thameswater using using the #tweetaleak hash tag. In the first four weeks, the service generated over 250 reports about leakages, around 9 a day. Due to the exceptionally cold weather in December, Thames Water was reporting nearly 300 leaks a day, four times the normal number at that time of year.

When the water in reservoirs drops below 5 degrees Celsius and enters Thames Water’s mains, especially the old cast-iron ones, they contract and in some cases break. The colder it gets the worse the problems gets. [...]  More than 20 per cent of London’s water mains are over 150 years old – the oldest in the UK – and more than 40 per cent are over 100 years old.

Thames Water supplies drinking water to 8.7 million customers in London and the Thames Valley.
