Pump test

During this weekend a nine hour long pump test was made in the existing borehole by the company Wedeco Ltd. The pumping started at 13 and finished around 22. Also a recovery test was made by me and Daniel for one hour after the pumping was finalized. Conducting the pump test during a weekend was the best solution since the water supply will be very limited. The hospitals need of water is less in the weekend compared to a normal weekday. 

A meeting with the company is planned on Thursday to discuss the results. Wedeco Ltd also works with fluoride removal from drinking water in other regions in Tanzania and a possible study visit will be discussed on Thursday.

Unfortunately one of the pipes broke when the old pump was inserted into the borehole again, causing a limited water supply for the past few days. However, spare parts were obtained from Shinyanga yesterday and the pump was back running by the evening.

Our plan for this week is to start with the electricity-part of the project. On Wednesday, Dr. Katani will show us the Eye Theatre, including machines which have a need for an uninterrupted power supply. A more extensive inventory will be on-going during the following weeks.

Also, on Wednesday there is a football game between Shinyanga – Kolandoto which we will attend to, and this weekend we will visit the Ngorogoro crater together with our neighbor, Lotta.

Advances in the water issue

So, the last week the work has been pretty hectic for me and Andrea (yes for most of the time that is his name here, the “s” doesn’t really come through for the Swahili speakers). Almost from the day we arrived, it was clear that the hospital was in need of a new pump for the drilled well that supplies the hospital and parts of the village with water. The current pump is old, ineffective and often breaks, which results in water shortages for the users. A new pump could for the short term ensure a more stable (and hopefully increased) water supply, even though a further increase in the supplied volume has to be established for the long term. Therefore, the recent work has mainly focused on finding an entrepreneur that can carry out the tests we need to be able to decide on the specifics for a new pump.

Yesterday we reached a conclusion regarding which company to work with, and in the end the choice was fairly simple. Out of three entrepreneurs found, one company did not have a pump of sufficient capacity, and another (a governmental agency for drilling and dam construction) gave a sloppy and unprofessional appearance. Needless to say we decided to work together with a third option, a local water and environmental developing company based in the regional capital Shinyanga (only 15 km from our village Kolandoto) called Wedeco. At the moment we are waiting for Wedeco to confirm the details in the contract we proposed to them. Then we will find Dr. Katani, the medical doctor in charge, to sign the contract before we have a ride arranged by the hospital for us to visit Wedeco a fourth time this week to finalize the deal. If everything goes according to the plans, the pump test will be done tomorrow, updates on that later.

In other news, the recent two days has been some of the hottest yet, well over 30 degrees at midday. Also, our next door neighbour has one or several roosters that remind us – load and clear – once ever other minute that it is still there. The lust for Coq au Vin has never been greater...

A need for a new eye clinic

A new exciting development of my task here in Kolandoto has happened! During the first day almost two weeks ago, we were showed around at the hospital and also had a meeting with some of the management and the people working with water. At that meeting it turned out that the hospital is planning to extend its eye department with a new building containing an eye clinic. The hospital was looking for funding to be able to construct this building, and were supposed to write a justification document showing why this eye clinic building is needed, and then pass the document on to an NGO that will start fundraising. So, I did a short and intense consultancy task of improving a draft of this justification document with more illustrations, pictures and texts over the weekend. This whole situation of a donor asking for a convincing and illustrative document justifying a need, is to me a clear example of that an architectural masterplan would be of great use for the hospital management to have ownership over the long-term development of the hospital.

Part of the problem is that the inpatient ward and the outpatient clinic for eyes currently are located within the same building. First, this causes a severe shortage of space to be able to accommodate all the eye health care services and it causes a lot of congestion in the entrance to the building. Second, the layout compromises infection control due to that inpatient and outpatient flows meet which could lead to easy transmission of diseases and infections among patients.

In the beginning of the following week we had a meeting with the whole management team at Kolandoto Hospital and Kolandoto College, where we discussed the whole collaboration project concerning infrastructure of water, buildings and electricity. The project was very well received among the management team. Matters ranging from the set-up of the project, to details of installing a new pump, and to concerns for the design of the new eye clinic building were adressed.

After some more in-depth discussions that has taken place the last few days, I have been asked to make a proposal for the design of the new eye clinic building. I am very happy to do this. And with a bit of luck there might even be available funding for constructing the building, depending on how the fundraising goes. Exciting times!

Studying local building methods

Now its been almost two weeks since I came to Tanzania - time goes fast when there is a lot to do! The first couple of days where spent in Mwanza. We took the opportunity to go to visit a site where they used a press to make interlocking stabilized soil blocks. Four people are needed to operate the machines, but at this production and building site they were many more to speed up the process. We got to see how the soil and cement are mixed, how the machine is operated, how the blocks are watered and cured, and also a finished example of a small building on site. 

We have also been here in Kolandoto village for some time now. I have been trying to better understand the local building traditions and techniques. At the hospital the buildings are mainly made out of concrete blocks with a plaster finish on the outside. The roofs are often made out of corrugated metal sheets laid on wooden trusses. The bricks are made by putting a cement and sand mixture in a wooden frame, and then letting the blocks slowly cure outside while watering them daily for a while. Piles of ready made concrete blocks are spread out at the hospital area. 

Yesterday I visited a more rural home and looked at other building methods. The older walls were made out of sun cured mud bricks, and they were quite visibly starting to fall apart from the outside. The roofs were made of wooded sticks and some plant material to cover. The owner of this home had started to produce mud bricks in a wooden form and then cured by burning them. However that seemed to be a tricky process since some of the burnt bricks did not get the same high quality. This was visible in the color of the bricks being more black instead of red, and it was possible to hear a clear difference in the sound of the blocks when nocking on them. The foundation on this site was made of stones and soil. 

Now I am going to leave this sofa at the guesthouse where most of the writing has happened so far and head up to the administration building where I got my own desk.

First days in Kolandoto

Almost a week has passed in Tanzania and we have started to settle in our new home. The village feels very safe and the people in Kolandoto are very friendly.  We have been assigned translators, Kassim and Robert, who have become valuable members of our team. In addition, technicians and staff responsible for the water system has helped us as well. The whole team is presented in the figure.

During the last few days we have tried to get an overview of the current situation here in Kolandoto. Our supervisor, Mikael, just left Kolandoto for other projects in Tanzania. Together we have mapped the whole water distribution system, from the borehole to the tanks. We have also investigated the current waste and sanitation systems here in the hospital.

We have also had meetings with the hospital management where we explained the whole project and discussed relevant infrastructure issues. 

The following days, me and Daniel will make assessments on the borehole in order to determine if more water can be extracted. This morning a pump test was made, where the water flow from the borehole was determined. Further test will be carried out this week to ensure the actual capacity of the borehole.

Examples of Sustainable Buildings in Nairobi

(blog post from the 4th, but posted on the 6th due to internet issues)

I, Annika, am now sitting at a hotel in Mwanza, Tanzania, and have finally found some time to write. I left Sweden 6 days ago and started my journey by going to Nairobi in Kenya to visit some friends and to do study visits to interesting examples of buildings and projects that apply some sustainable building principles. 

The first building I visited was the Learning Resource Center at the Catholic University in Nairobi. It was designed by architect Musau Kimeu, and is an excellent example of a building that adopts sustainable building techniques appropriate for a tropical climate. To create a comfortable indoor climate it combines passive ventilation through the ’stack effect’ with passive cooling through a rock bed heat exchange system. Hot outdoor air is drawn in and cooled down by a rock bed located under the main seating area before it is let out in the conference hall, in which the air slowly heats up and rises due to the stack effect before it is let out through the roof. Sun shading outside windows that are adapted to the amount and direction of sun is also used. For example, a combination of large overhangs and horizontal shading devices are used to prevent direct sun from reaching the windows and overheating the interior space. The rock bed heat exchange system.

The second project was a Skills Center for the Youth of Nairobi. It was a boarding school set up in the outskirts of Nairobi where youths could come to learn practical skills like metal work, woodcrafts and sowing. The center was built using local materials. The walls were made of stone from a local quarry nearby, and the roofs were made of bamboo from the Aberdares area in Kenya. All the furniture used in the center was of course made on site by the youths. There was also a clear systemic approach to natural resources. The toilets were separating urine and feces, and both were reused in different ways in the garden. Electricity was provided by solar panels on the roofs. 

The last study visit in Nairobi was to an engineering company that makes block presses used for producing interlocking stabilized soil blocks (ISSB), called Makiga Engineering. There are several benefits as I see it with using the ISSB press. First, is that the cost of the building will be drastically less than when building with for example concrete blocks, due to that the soil block technique will  require much less cement to make, and the interlocking building technique requires very little mortar in comparison to non-interlocking. Second, the material used for construction of a building can most often be the soil existing on the site. Third, the machine takes four people, with a little bit of training, to operate which means that you bing an income generating activity to the local community using the technique. 

Andreas and Daniel just arrived, and now we’ll go out to explore Mwanza.
