Once a year Google hosts the ‘Geo for Good User Summit‘ where they invite mapping and technology specialists in the public benefit sector, who are actively working on projects related to mapping. SamSamWater was invited to join this event to learn, share and meet with the Google Earth Outreach team and other mapping specialists.

Sander de Haas gave this ‘lighting round’ presentation on how SamSamWater and Justdiggit are using geo information and mapping tools for their work in Africa.

We’re glad to announce that VIA Water has approved the Improving Sustainable Groundwater Exploration with Amended Geophysics (ISGEAG) project proposal.

Together with Acacia Water and KenGen (Kenya Electricity Generating Company Limited) we will try out and compare different geophysicial groundwater exploration methods at three sites in Kenya and set up new guidelines for exploration.

In Kenya, current groundwater exploration methods do provide insufficient information and are poorly applied. Hence, conclusions and recommendations are often ambiguous, inconsistent, sometimes incorrect and even misleading. These errors lead to high numbers of dry and saline wells, unnecessary deep drilling, unexplored groundwater reservoirs and poor groundwater management.

This project aims to apply traditional, existing and new geophysical methods in three reasonably well researched areas (Mombasa, Kajiado and Kakuma) to show the limitations of different geophysical methods, study their best combination for each different context and improve the interpretation of the measurements. An on-the-job training trajectory runs parallel to the research programme.

The project leads to better drilling results and more sustainable abstraction of groundwater. Hence, the burden of fetching water is alleviated and occurrence of water-related diseases reduced. This particularly benefits the urban population, the poorest, women and children. The project is proposed by a team of Kenyan and Dutch experts.

Op 30 oktober 2015 heeft een benefietavond plaatsgevonden voor de bewoners van Mude in Nepal. SamSamWater heeft hier het waterproject nader toegelicht.


In de droge periode kampen de dorpen met een gebrekkige watervoorziening. SamSamWater heeft in april 2015 een missie uitgevoerd naar Mude Nepal om het watersysteem in kaart te brengen en de watervoorziening te verbeteren. Met de benefietavond, georganiseerd door stichting Tashi Delek, is geld ingezameld om de bestaande watervoorziening te repareren en te verbeteren.

Presentatie SamSamWater watervoorziening Mude Nepal



We sympathize with everyone who is directly or indirectly affected by the terrible earthquakes in Nepal.

Lucas Borst and Cedrick Gijsbertsen just returned a few weeks ago from a field survey in Nepal for our project in Mude. They brought back a Geological Map of the Eastern part of Nepal which we have scanned and made available online for anyone to use.

We have several options to view or download the map:

If you have any data that might be helpful to others: please let us know and we can help you to make it available by digitizing, processing or hosting the data!

The SamSamWater team is getting busy. It shows that our specialized water knowledge and enthusiasm are more and more needed in the projects in developing countries. To keep leading the organisation and projects  in the right direction, the board is strengthened. Lucas and Maarten had been a partner and now join the board. A new step in the development of SamSamWater!


From 30 November to 5 December 2014 a team of SamSamWater experts participated in a Knowledge Exchange mission of the SUSWA project in Kajiado, Kenya.

The presentation with concluding remarks is shown below. For the mission report and presentations of this week visit the SUSWA website.

Today Sander de Haas gave a presentation on Low-cost innovations for water and sanitation.

The presentation is in Dutch (but contains mainly pictures!) and can be viewed below:

The latest mission to Wiggins Primary School in Kumi Uganda resulted in 2 successful boreholes. The boreholes are both fitted with handpumps. The water from the boreholes will be used as drinkingwater for the 1000 pupils of the primary school. The first results of waterquality- and capacitytests of the boreholes are positive.


For the next 6 months the quality and capacity of the boreholes will be monitored by the schoolstaff and -children. After these 6 months the results of the monitoring and the possibilties for an upgrade to a solar powered system will be evaluated.


Backgrounds of the project can be found on:




Terrameter in progress

The Wiggings Primary School is located in the East of Uganda. The Foundation ” Kyoga Steunfonds” has supported the school since 1980 by providing educational material and renewing the school classrooms. The school has an increasing number of pupils (up to 1000 pupils in 2011). For drinking water and sanitation these pupils and the school staff more heavily rely on the town water system, which is subject to power losses and mechanical problems. Mainly in the dry season this causes shortages on drinking water for the school pupils.

Supported by the foundation “Steunfonds Kyoga”, SamSamWater carried out a hydrological field study in 2012 to gain information on different possibilities in accessing safe and clean drinking water for the school. The field study resulted in a technical advice and recommendation for the most suitable and sustainable option for the school. For the school a (low capacity) borehole appeared to best option to be able to provide save drinking water. At first the borehole will be fitted with a handpump and will be upgraded to a solar powered system at a later stage (when the usage and maintenance of the system is regulated).

In october 2013 a new mission will be carried out. SamSamWater will assist and supervise the geophysical survey, the drilling and testing of the borehole.

To train the AMREF and other Kenyan WASH Alliance (KWA) members in their efforts to provide
sustainable water access a Knowledge Exchange mission was carried out. This mission is part of the SUSWA (Scale up of Sustainable Water Access) project by WML, Aqua for All and AMREF.

During this Knowledge Exchange mission SamSamWater gave a training on using Google Earth, GIS tools and GPS functionality for water projects. The participants were trained in using Google Earth and other tools to prepare for field visits and siting of 3R water projects. Furthermore the participants were trained in using GPS apps on their Android smartphones to measure and collect data in the field.

All participants were enthusiastic about the possibilities of these tools in making their work more efficient. The mission report and links to all the websites and Android apps can be found here: http://www.samsamwater.com/suswa/.
