Watersupply for St. Mary’s Hospital in Isingiro (120 beds)


Country: Isingiro, Tansania
Task: Spring preparation and gravity-fed water supply
Scope: Turnkey (planning, delivery, construction) beginning with supply network, including pipelines, reinforced concrete tanks, (domestic) connections
Project Partner: BSI Innsbruck
Duration: February 2010 to February 2011


St. Mary’s Hospital is now supplied with drinking water from Isingiro via a pipeline of about two and a half kilometres. The project followed an ecological rehabilitation strategy with work commencing in early 2010. First of all, a spring had to be located and made accessible; this was achieved by digging horizontally into the mountain at the spring outlet. A shaft consisting of three chambers is used to purify the water. The steep decline required the construction of an intermediate tank about 150 metres below the spring in order to reduce the pressure within the pipeline. Along the pipeline two additional control shafts were created which are used for inspection and maintenance.

The water is collected in two newly created tanks of reinforced concrete with a capacity of about 200 cubic metres. Beginning from there, about 800 metres of plastic pipes were installed to provide the separate buildings – as well as the flats of the employees – with drinking water. At the hospital itself, ten water taps were installed for patients and their relatives.

Watersupply for Mary Immaculate DOR Hospital, Mapuordit (150 beds)

Country: South Sudan, Diocese of Rumbek
Task: Drinking water excavation from two wells fed into a steel tank, newly laying the supply grid (1,250m), construction of 30 domestic connections in the hospital and another 10 water collection points
Solar pumps: 2 solar generators, each with 16 solar panels, 1,280 watts total power
Water storage: Water tower with a capacity of 20,000 litres, mounted on a steel frame at a height of 6m
Project partner: Comboni Missionare of Rumbek Diocese
Duration: September 2010 to February 2011


At the turn of the year 2010–2011 there were great fears that the impending division of Sudan into a northern and southern part could again lead to political unrest and armed conflicts. This had a large impact on projects within the region: all efforts were focused on swift completion. Likewise, the water supply project for the Mary Immaculate Hospital in Mapuordit (Rumbek) was to be implemented within the least amount of time possible. BBM was involved in a planning and executive role.

Despite the urgent situation, the system was installed with all due diligence. Drinking water from two wells is fed into a water tower via two solar pumps. The hospital’s diesel generator ensures that the pump can also be operated during the less sunny wet season. The water collected in the water tower is fed through plastic pipes (total length 1,250 metres) to the building connections and water collection points. In terms of quality standards the components for the new water supply system were not available either locally or regionally. Consequently, the pipe material was imported from Uganda, plug cocks and sliders came from Austria.
