On May 30, 2018, the participants of the Transition Management process, multiple actors active in different organisations and sectors such as the government, NGOs and the University, visited different informal settlements in Arusha with the aim to learn about local challenges and opportunities (e.g. innovative projects and initiatives).
Interview with Hezron Philipo, GroFutures by Sean Furey, Skat Foundation
Hezron Philipo has a BSc in Geology (University of Dar es Salaam, Tanzania), MSc in Water Resources and Environmental Management (University of Twente at ITC, The Netherlands) and is currently doing his PhD research at Sokoine University of Agriculture in Tanzania as part of the UPGro GroFutures project.
I caught up with him at 41st WEDC Conference in Nakuru, Kenya, where he explained the research that he is doing and what new insights him and his colleagues are uncovering.
The GroFutures Team, working with the Tanzanian Ministry of Water and Irrigation, expanded monitoring infrastructure in the Upper Great Ruaha Observatory (UGRO) to include interactions between groundwater and surface water.
An outstanding question regarding the sustainability of groundwater withdrawals for irrigation and drinking-water supplies is whether groundwater in the agriculturally intensive lowlands is replenished by river flow, sustains river flow, or both depending upon the season.
Arusha is one of the faster-growing cities in Tanzania. The urbanization process is causing multiple interconnected problems. The first arena meeting organized as part of the T-Group Arusha Transition Management process was held by the local transition team with the aim to identify the existing community problems in Arusha. Below we briefly describe the findings from the first Arena meeting.
We caught up with Shabana Abbas, who was part of the T-GroUP project and is second author on a new UPGro paper entitled: “The emancipatory promise of participatory water governance for the urban poor: Reflections on the transition management approach in the cities of Dodowa, Ghana and Arusha, Tanzania.“
UPGro: Where are you from and how did you get involved in UPGro?
SA: I am from Pakistan. I got involved in UPGro in 2015, when I was pursuing my MSc at IHE Delft Institute for Water Education in the Netherlands.
UPGro: What research activities did you do as part of the T-GroUP project?
SA: I was offered the opportunity to undertake my masters research under the T-GroUP project, one of the consortium projects of UPGro. My research was about urban water supply and groundwater governance in Arusha city in Tanzania. I took a multi-scale approach and collected mostly qualitative data through in-depth interviews at ward, city and at the basin level.
Some of the key actors that I interviewed were residents from six different wards (lowest administration units within the city), Ward administrators, employees of the Arusha Urban Water Supply and Sanitation Authority, Arusha City Council and of the Pangani Basin Water Board. I also interviewed selected industrial/commercial users of groundwater such as bottled water companies, breweries etc. Moreover, I interviewed drilling companies operating in the city.
Through all my research activities including document analysis, I aimed to understand who is using groundwater, where, why and what does it say about the overall use of groundwater in Arusha. I tried to explore how this use is governed (if) for both environmental and social needs.
UPGro: What were your highlights of being part of the UPGro programme?
SA: For me there were three things:
Firstly, the opportunity to collaborate with researchers from different institutes/universities such as the team at IHE Delft, Netherlands, Dr. Maryam Nastar (Lund University, Sweden) & Dr. Hans Komakech (Nelson Mandela Institute, Arusha, Tanzania), who are all part of the T-GroUP.
Secondly, the entire experience of living in Arusha for three months with two other IHE students, also working under the project. All three of us looked at different aspects of groundwater in Arusha. I enjoyed the process of finding out new details every day and discussing/comparing these with the fellow researchers.
Finally, the chance to work with Dr. Michelle Kooy & Dr. Margreet Zwarteveen, my supervisors who have inspired me and supported me throughout my research.
UPGro: What did you take away about the links between groundwater use (or lack of it) and poverty?
SA: There are two sides to it:
Firstly, most of the boreholes and wells in the areas I visited were mostly owned by people from higher socio-economic class and that prices that they charged to other households (mostly to ones who could not afford to have their own wells and boreholes) varied and were unregulated. This makes me wonder if groundwater is really for the urban poor if they have to spend quite some amount on it?
Secondly, I found the higher concentration of fluoride in groundwater in Arusha limits its use for non-potable uses only. This means that if groundwater supplied at fair price to the poor can actually lessen their overall expenses on water. . I learned that groundwater plays a big role in the different household water supply combinations. For instance, in the six different areas of the city, people (both from high and low socio-economicbackground) used 28 different household water supply combinations and about 50% of these included water from boreholes and wells.
UPGro: What did you do next, and where are you now?
SA: After graduation, I joined Aqua for All in the Hague, Netherlands. Here, I work on a water innovation programme (VIA Water) that supports innovations addressing urban water & sanitation challenges in seven countries in Africa. One of the key areas of innovation that we support is for ‘sustainable use of groundwater resources’ and we have some interesting innovations being piloted in these countries. You can find out more about these projects here: www.viawater.nl/projects
UPGro: How did being part of the UPGro T-GroUP project help you, or steer you in new directions?
SA: Prior to my masters, I worked on rural water supply projects in the north of Pakistan. There, water was mostly sourced from springs. Participation in T-GroUP allowed me for the first time to study groundwater in detail. I was able to see what groundwater means for urban water supply in Arusha and in other African cities.It was all very new for me. I was quickly able to find out how serious the issue of groundwater governance is in many developing countries. My research in Arusha made me very curious and interested in water issues in Africa. It also motivated me to take on the job I am doing at the moment.
UPGro: What advice would you give to other young people who would like to get involved in African water issues?
SA: Go out there with an open mind; Don’t be afraid to ask the ‘why?’ questions and remain critical.
UPGro: What can programmes like UPGro do to support young researchers and young professionals in their careers?
SA: Offer more opportunities to young researchers to share their work through webinars and other mediums. Moreover, after students finish their research work, offer them some sort of fellowship for translating their work into knowledge products for wider/non-academic audiences.
UPGro: Finally, what changes would you like to see in the way that groundwater is managed across Africa?
SA: First, I would like that groundwater be recognized as an essential resource that needs to be governed in a socially equitable and ecologically sustainable way.
And second, I would like that local actors take responsibility of ensuring that groundwater is not overexploited. They should make efforts to utilize the UPGro/other research work and see how policy level changes on groundwater can be informed by that.

The GroFutures team in Tanzania has just completed the data collection component of the Participatory Rural Appraisal (PRA) exercise in the Great Ruaha Basin of Tanzania. The team comprised Andrew Tarimo, Devotha Mosha Kilave, Gebregziabher Gebrehaweria and Imogen Bellwood-Howard. Following initial training at Sokoine University of Agriculture, the team moved to the study site in Mbarali District and worked in three villages (Matebete, Ubaruku and Nyeregete) between 23rd August and 2nd September 2017. During the PRA exercise the team carried out a range of activities including seasonal calendars development, long-term trend analyses, wealth indexes, technology rankings and a well inventory (see photos below).
The team documented a range of groundwater and other water use strategies involving dug wells, shallow and deep groundwater wells alongside surface water and natural springs. With the well inventory, the team was able to locate geographically groundwater sources within the study areas. The PRA exercises allowed the team to make qualitative characterisation of different water sources. Preliminary data include the observation that wealthier people were often beginning to invest in more expensive, private infrastructure. Quality was a concern as much as quantity, which was highly relevant in the light of recent health scares. A detailed analysis of the entire survey dataset is curently being carried out by the team.

The GroFutures team at Sokoine University of Agriculture (SUA, Tanzania), led by Japhet Kashaigili (SUA) with support from PhD students, Hezron Philipo (SUA) and David Seddon (UCL), established in July (2017) a groundwater-level monitoring network in the Upper Great Ruaha Basin Observatory in southern highlands of Tanzania. This area is part of the Southern Agricultural Growth Corridor of Tanzania (SAGCOT) where increased use of groundwater and surface water is anticipated to support agricultural production. Constructed monitoring wells at depths ranging from 18 to 32 m below ground were drilled using a PAT-DRILL 421 rig. The team also instrumented monitoring wells recently constructed by project partners at the Rufiji Basin Water Board (RBWB) in the Tanzanian Ministry of Water and Irrigation.
The new monitoring network comprises an upstream location at Chimala at the base of an escarpment and a downstream location at Mbarali within the alluvial plain. A monitoring well at Chimala Secondary School was installed into coarse unconsolidated sands and gravels to a depth of 26 m. This monitoring well is linked to both an additional monitoring well at Usangu Secondary School and a river gauge. Both monitoring wells are equipped with automated dataloggers providing hourly groundwater-level measurements. A third borehole was constructed at Chimala Primary School though no groundwater was encountered up to a depth of 30 m. At Mbarali, two monitoring wells were constructed on the St. Ann’s Secondary School and now form a transect of 4 monitoring wells as the team also instrumented two monitoring wells recently constructed by the RBWB at Rujewa at Mbarali Secondary School and Jangurutu Primary School.
The new infrastructure is expected to reveal for the first time the dynamics between groundwater and surface water in the Upper Great Ruaha sub-catchment of the Rufiji Basin and answer key questions around the nature of groundwater recharge and whether seasonal river flow recharges groundwater or groundwater sustains river flow. Further work will also seek to ensure that this observatory is equipped with both tipping-bucket rain gauges to record sub-daily (hourly) rainfall intensities and soil-moisture probe arrays to better understand how intense rainfalls are transmitted through alluvial soils.
Shallow groundwater wells, are the main source of drinking water in many rural and peri-urban communities.
The quantity and variety of shallow wells located in such communities make them more readily accessible than private or government operated deep boreholes, but shallow wells are more susceptible to faecal contamination, which is often due to leaching pit latrines.
For this reason, online monitoring of water quality in shallow wells, in terms of faecal pollution, could dramatically improve understanding of acute health risks in unplanned peri-urban settlements.
More broadly, inexpensive online faecal pollution risk monitoring is also highly relevant in the context of managed aquifer recharge via the infiltration of either stormwater or treated wastewater into the subsurface for aquifer storage and recovery.
To tackle this challenge, IN-GROUND – an UPGro Catalyst Project – trialled four different types of Microbial Fuel Cell (MFC) water quality biosensor in the lab (Newcastle University, UK) and in the field (Dar Es Salaam, Tanzania).
While further work is needed, the results provided proof-of-concept that these biosensors can provide continuous groundwater quality monitoring at low cost and without need for additional chemicals or external power input.

Professor Japhet Kashaigili presented recent research from the GroFutures Site Observatory in Tanzania (Makutapora) at the 4th Annual Conference (AWAC 2016) of the Association of Tanzanian Water Suppliers (ATAWAS) held on 8th and 9thNovember 2016 in Dodoma, Tanzania. Under the theme of “Knowledge, Capacity and Learning in the Water and Sanitation Sector,” the development of water supplies and sanitation as well as the current challenges faced by organisations across Tanzania were discussed by professionals working in water sector including policy makers and those involved water governance.
Professor Japhet Kashaigili, based at Sokoine University of Agriculture (SUA), presented a paper entitled, Assessing the sustainability of groundwater-fed water supplies to intensive pumping and climate variability: evidence from detailed monitoring of the Makutapora Wellfield, drawing on collaborative research conducted by SUA, University College London, University of Sussex (UK), and the WamiRuvu Basin Water Board within the Ministry of Water and Irrigation. Key stakeholders including the Dodoma Regional Administrative Secretary and Technical Manager of the Dodoma Urban Water Supply and Sanitation Authority (DUWASA) expressed great interest in the GroFutures Team’s evaluation of the sustainability of intensive groundwater abstraction from the Makutapora Wellfield, which is currently the sole perennial supply of freshwater to the rapidly growing capital city, Dodoma. Japhet’s presentation highlighted the bias in wellfield replenishment (recharge) to heavy rainfall and the observed dependence of recharge on the duration of ephemeral river discharge to the wellfield. He also reported on the establishment of telemetry-based, high-frequency (hourly) monitoring of groundwater levels in boreholes enabling the WamiRuvu Basin Water Board and GroFutures team to download real-time monitoring of groundwater levels for wellfield management and research.
