The Holy Family Hospital Nyapea is located in the district of Zombo in Uganda and exists over 31 years. In cooperation with Eine Weltkreis we want to improve the water and power supply of the hospital.
This hospital is one of a few places of the world where patients get regularly medicated. The pest is not exterminated in this area. Furthermore a lot of caesarean sections are carried out as women have very narrow pelvis in this region.
Because of the rural location in the West Nile region in the north of Uganda, there is no reliable power and water supply. So far a small single phase solar system supplies the main loads, but for a perfect function it would be necessary to switch to a three phase operation. The present inverter is unable to supply the load peaks. In case of a breakdown the hospital does not have suitable spares. The existing lead acid batteries which are on the limit of their living duration have to be switched very fast. A perfect alternative for the replacement would be new salt water batteries which are perfect for hot climates. Also the duration of living is more than 10 years.
The existing borehole should be operated with a solar pump to decrease operating costs. Because of troubles in operating the pump system on government compound the hospital was forced to relocate the whole equipment. A new compound was buyed and fenced. The equipment should be installed on a new building where also the emergency generator can be kept. Furthermore it serves as accommodation for the secret service.
|Occupancy rate||in average 78%|
|Outpatients||19.500 (Sept. 17 – Sept. 18)|
Two volunteers (students) have under the supervision of BBM installed digital electricity meters in eight catholic hospitals in Uganda. The evaluation helps hospitals to save energy and shows the profitability of existing solar power systems.
In the installed electricity meters the technicians of BBM integrated a data storage which plots the consumption of power. Financier is DKA (Dreikönigsaktion). The target of the project was to offer the technicians of the hospital a possibility to overview the electric systems and to recognize and correct diverse problems early. In a few hospitals this power monitoring system was used earlier. In this way a comparison with the data was possible in the latest years.
In addition, the staff were interviewed on site. The target was to find out the energy consumption for the near future. From information about the actual energy consumption and the planned future development, the BBM calculated a load profile. The basis to this is a strategic development plan for the next five years. The aim of the project was, on the one hand, to raise awareness of the actual electricity consumption and to find potential savings. On the other hand, to determine the investment costs for a partial or complete power supply using photovoltaics (PV). The results of this study were passed on by the BBM to the hospitals and their umbrella organization in order to be able to react to the savings potential found and to convince potential donors of the sensibility of new investments in this area.
The load profile of St. Joseph’s Hospital in Kitgum shows that around 25% of the total electricity requirement (orange area in the diagram) is already covered by the PV system installed in 2017. The remaining approx. 75% (gray area in the diagram) – depending on availability – is provided by the power grid or a diesel generator. Another result of the study was that there is a relatively large potential for savings by switching off devices that are not required, as well as by replacing traditional lamps with economical LED lights. This is especially true in the evening and night, when there is no solar energy available to reduce the electricity required from the grid or a diesel generator. It was also determined what additional solar power would be required to cover the hospital’s electricity needs as fully as possible in the future with solar power. The installation of another PV system with 25 kWp is expected to be carried out as early as 2019 to 2020. According to this calculation, the solar power will then be able to cover around 40% of future electricity needs.
In spring 2017 BBM received the order to support the St. Josephs Hospital in Kitgum (UGANDA) with the installation of a photovoltaic system.
The unsteady electrical power supply and breakdowns handicapped the hospital work enormously.
On November 28th 2017 the PV system was successfully tested and handed over to the hospital. Already on the following day, a Sunday, from 09:00 a.m. on, the hospital was fed entirely by the PV system. On weekdays the feed-in of the PV will be between 25 and 30 %. A first and important step for a smooth, efficient and economic electrical power supply fort the hospital.

The St. Luke Hospital in Angal, north-west in Uganda, is for 180.000 people the only place, where qualified medical care is possible. But the infrastructure of the hospital is outdated. The income of the “Community Hospital” can hardly pay the regular costs, like salary, power supply, etc.
To make sure that the quality of medical care is safe a restructuring from parts of the hospital was indispensable – implanted by BBM as the general contractor. The restructuring was made in 2 years (2015 – 2016) in the following sectors:
The BBM has been implementing ecological restructurings of Hospitals in East Africa since 1995 with donations of donor organizations. Core sectors are ecological power supply, drinking water supply as well as wastewater and waste Management.
However not the implementation but the human is the important aspect. Together with the Project partner and other involved Partners (e.g. the surrounding municipalities) the Project aims defined and realized. An important component of the implementation is the passing on of the Know-How to the local technicians through Workshops, for which also experts from bordering Hospitals are invited. This makes a best-practise exchange within Africa possible and the support of the local Know-How. Furthermore, besides the improvement of the Health care as well as the ecological thought is transmitted

Around 4000 people are staying in St. Mary’s Hospital in Lacor, Gulu, Uganda per day-patients, medical staff and visitors. The Hospital has water supply facilities, which get their water from a number of wells. The waste water is collected by a central sewer system and is going to be poorly cleaned in the wastewater lagoons. Especially this insufficient preparation of the wastewater requires action.
An efficient waste water preparation is important, because without it, it would be impossible to eliminate the pathogens in the waste water. Since there is the danger that resistant pathogens get from the groundwater into the drinking water. And because of that cause a disease cycle: The bacteria contaminated water is going to be pumped out of the well and gets like this back in the human body. This cycle should be stopped, so that no water based diseases could expand. The supply with clean water and the access to appropriate sanitation systems are the main challenges in this development cooperation. The enhancement of sanitation and water supply is an important component in the fight against poverty and the destruction of the environment, which is also said in the Sustainable Development Goals of the UN, as well as in the Laudato Si, the environment encyclical of the pope.
Dipl.-Ing. Josef Sperrer, a civilian engineer, planed the order of Horizont 3000 the plants for an improvement of the water supply, the use of rainwater and the preparation of wastewater according to legal requirements. After solutions were found and the planning was coordinated together with local decision makers, the needed jobs were publicly advertised. The BBM could win this tender as the best and cheapest supplier and was instructed to realize these actions.
So far the wastewater in St. Mary’s Hospital was directly brought to the wastewater lagoons without any preclearing, so that they silted as a result. From now on the wastewater is mechanically cleaned in a sedimentation tank with a usable volume of 300 m³. The sludge, which is settled down in the tank, is going to be pumped away and used for agriculture.
The wastewater lagoons clean the water only insufficient. To clean the 200 m³ wastewater per day according to legal requirements an overgrown soil filter with approx. 850 m² patch surface was constructed. This soil filter is a combination of biological sewage plant, trickling filter and a solid reactor. The wastewater is gets intermittently to the biological level and is sprayed by an extensive laid piping on to the surface.
In the hospital the rainwater is used for the lab and the washing facilities. For the storage of the rainwater underground tanks per 50 m³ usable volume were built.The plants were built very professional by local experts.
Norbert Demmelbauer: „We have worked with Dominic Ocaka and his employees since years. Because of his great competence, he makes the realisation of this project a lot easier.”
The check at the water supply network showed that around 30 % of the transported drinking water gets lost because of various leaks. Mainly dripping fittings, old sealing but also regular leaks could be found. Alain, an Austrian plumber, trained the local plumbers. From now on local plumbers could do the necessary work themselves.
Due to the efficient use of available materials, a sanitation area could be completely renewed. For the first time built in cisterns were used. And also the partly corroded iron pipes were renewed.
The experts of BBM set together with Josef Sperrer new standards for the wastewater cleaning. The newly developed overgrown soil filter can clean large amounts of wastewater with a high quality and is suitable to upgrade insufficient plants.
ASIC (Austrian Solar Innovation Centre) is a research partner of BBM. Within a new project the ASIC could help the BBM for the development of a hybrid energy management to support energy systems.
Especially in developing countries the quality of the power network is not really satisfying most of the time. Failures and fluctuations of the operating parameters make the supply of vital devices, e.g. in a hospital, to a complex task. As a substitution expensive diesel motors are used. From now on they try to integrate PV plants, which make the power clearly cheaper, into the energy systems. A variety of configurations were tested with simulations, to find out, which is the best combination of PV and diesel generators. A core element was the development of an optimised energy management system regulating the interaction of the individual components during operations and collects at the same time data for an automatic review of the system for the error detection. In the next step the energy management can be integrated into the efficient control system (PLC), because of the knowledge gained. It also can be used in affected areas and plants.
In the meantime this PCMS (Power Control & Monitoring System) is used in two radio stations and one hospital
|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.
