|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.
|Location:||Aber, Uganda (Lira Diocese)|
|Task:||Planning and construction of three major buildings and three outbuildings, planning and implementation of infrastructure (water, sewage, energy)|
|Duration||January 2009 to November 2011|
|Project partner:||Seraphisches Liebeswerk (SLW) of the Capuchin and Lira Diocese|
BBM was commissioned by SLW with the planning, the coordination of construction and installation of all technical equipment. A BBM staff member from Uganda was responsible for supervising the local construction and the on-site coordination of companies. BBM experts from Austria supervised the progress of work via regular business trips to the project.
First, the relevant plot of land was purchased, cleared and fenced-off. Additionally, an access road to the building site had to be created. Next, a well was dug, feeding a 20,000-litre water tank via a solar-powered pump. Three main buildings were constructed: the accommodations for girls and boys, each with 108 beds and a central service building with assembly hall, kitchen and offices. There were three outbuildings: a sisters’ house and two guest houses for short-term or long-term guests. All rooms were furnished and included complete plumbing and electrical installations. BBM were also responsible for landscape development and the creation of access roads.
The complex of buildings in St. Clare was constructed according to an overall ecological concept. Greywater from hand washbasins, showers and sinks is treated in a horizontal soil filter and reused in water-efficient flush toilets. Rainwater is collected in two 20-foot containers and used amongst others for laundry. Blackwater is collected in a three-chamber plant, pre-cleaned and fed via a solar pump to a two-tiered constructed wetland, at which the second soil filter (size: approximately 100sqm) is fed by a mechanical lifting mechanism entirely without the use of electricity. The treated wastewater is collected in a tank and used for the irrigation of the plantations and green spaces.
Sensor lights with integrated motion detectors and energy-saving lamps reduce energy consumption. Various photovoltaic systems provide the electricity for all three pumps, the emergency lights within the buildings, the street lamps and three freezers. Twelve solar heating systems with a 300-liter tank provide hot water for showers, sinks and washing.
Feedback from the project partner:
“All the people are fascinated by the system since they have never seen such a big system and it works well. Everybody is very happy and I think they are thinking of other places since power in Tanzania is very erratic. Someone told me that it was a blessing because after the installation power rationing started.”
