This publication provides background on select EMAS household water supply technologies to the wider sector audience. It assesses and presents experiences with these technologies as used in Bolivia. The document provides: (1) an overview of EMAS household water supply technologies (specifically the EMAS Pump, a percussion-jetting-rotation manual drilling method, and rainwater harvesting systems) and of EMAS’s approach to im-proving water supply, and (2) an independent assessment of these EMAS technologies as used in Bolivia. Reference is given to other available resources related to EMAS technologies, including EMAS training videos that are available on the internet.

Evaluation of Hand Augered Well Technologies’ Capacity to Improve Access to Water in Coastal Ngöbe Communities in Panama MSc thesis submitted to University of South Florida 2014

In Panama, the indigenous Ngöbe people in the ÑöKribo coastal area are a group disproportionately affected by a lack of improved access to drinking water and challenges to the feasibility of piped gravity fed water systems that typically serve the rest of the country. An NGO aiming to ameliorate this situation introduced two improved groundwater supply technologies to the region: bailers and EMAS hand pumps. This study assesses the comparative performance of these systems while evaluating the respective performances of existing water sources, using the wide variety of quantitative and qualitative data obtained.

The 2016 Rural Water Supply Network Forum in Abidjan was the first global gathering to consider the practical challenge of how everyone worldwide can get access to safe, affordable water by 2030. It was also the first RWSN Forum to take place in a francophone country, in the 25 years since the creation of the network.
The Forum gathered 467 rural water sector practitioners from over 300 organisations from 64 countries in Africa, Asia, Americas, and Europe, in a bilingual (English/French) four day event. It was opened by the Prime Minister of Côte d’Ivoire, Mr Daniel Kaplan Duncan. We were joined by HE State Minster James Dengchol Tot, Minister of Water, Irrigation and Electricity of Ethiopia, as well as a delegation from AMCOW.

This Forum proceedings compiles all peer-reviewed materials. Separate downloads and links to the films can be found at: https://rwsn7.net/content/

RWSN Handpump Survey 2013 Summary of Findings

Downloads: 747


Author: FUREY S. G.
Year of Publishing: 2013
Publisher: Skat Foundation
Institution: Rural Water Supply Network

Manual pumps have been used for centuries but this simple technology remains the mainstay of rural water supplies in many countries. The Handpump Technology Network (which later became RWSN) was set up in 1992 to promote collaboration and standardisation so that handpumps could provide more reliable and better quality rural water services.

This survey is aimed at practitioners in government, NGOs, private sector and development partners who are directly involved in rural water service implementation, or who are involved in the procurement of handpumps or spare parts (as either a buyer or seller).

Handpumps: where now? A synthesis of online discussions (2012-2014)

In 2012, RWSN established Dgroups.org as its online electronic platform for membership and discussion. The groundwater and handpump groups have been among the most active communities. The number and depth of contributions has been rich, and several members have asked for a synthesis of the discussions. They main topics that emerged were:
1. Water Quality - particularly iron and pump corrosion
2. Procurement, Quality Control and Installation
3. Sustaining handpumps - what is the average lifespan of a handpump?
4. Handpump component failures and the need to redesign public domain designs
5. The politics of new pump designs: the Squirrel Cage Pump

Baptist Drilling

Author: CLOESEN, P.
Year of Publishing: 2007
Publisher: unpublished
Institution:

Baptist drilling is similar to hand sludging, with some percussion drilling combined. The main difference is that while sludging relies on a person's hand at the top of the drill pipe as a valve, the Baptist method uses on a valve at the bottom of the drill pipe.

Institution:

The drilling method developed by the Escuela Móvil de Agua y Saneamiento (Mobile School for Water and Sanitation) in Bolivia is a hybrid between washboring, percussion and rotary drilling. It permits to drill through all kinds of loose soils, as ell as consolidated materials and light rock. It will not, however, penetrate hard original rock or boulders (e.g. ancient river beds underground)

What’s Working, Where, and for How Long A 2016 Water Point Update to the RWSN (2009) statistics

• An average of 78% of water points are functional across the 11 countries analyzed.

• The high failure rates early after installation are troubling: almost 15% after one year and 25% of water points are non-functional by their fourth year after installation. This indicates widespread problems with poor quality water point installation, due to a range of problems that may include professionalism and skills around contracts, construction and supervision; borehole siting; lack of quality control of hardware; or lack of post-construction monitoring and problem resolution.

• Handpumps are often singled out as technology that fails, but analysis of other water point types show similar functionality levels, and that tens of thousands of handpumps are providing a service
