The WASHTech project has published a literature review  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

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.

UNICEF has published WASH technology information packages (TIPs) , a practical set of guidelines and selection tools for WASH programme and supply staff.
The following WASH technologies are covered:
- Hand pumps for drinking water
- Boreholes and drilling equipment for rural water supply
- Solar powered pumping
- Motorized and small piped systems
- Faecal sludge emptying equipment
The TIPs are linked to Excel spreadsheets giving selection tools and bills of quantity.
Originally written for UNICEF WASH Programme Officers (each of whom have received the package on a USB stick), the TIPs have now been made available on the UNICEF web site. They are free to be reproduced as long as UNICEF is credited as the source.
