St. Francis Hospital in Marial Lou is the major hospital in the region. The hospital has changed their activities from an emergency hospital to become a permanent hospital for the surrounding communities. And also the number of patients has constantly increased over the last years.
The handed over structures from MSF (Médecins sans Frontières) are all non- or semi-permanent structures. The life span of such structures is normally between 3 to 15 years. Within this period, all buildings must be renewed or renovated.
The existing operating theatre is a non-permanent structure using mud bricks as walls and inadequate floor, ceiling and roof constructions. Open windows are the only ventilation system.
It is not possible to fulfil minimum hygienic standards with this situation.
The new operating theatre is planned based on international hygiene standards and norms. The major technical aspects are:
Patient handling cycle:
There is a separate patient handling cycle which allows
Equipment / Material cycle:
High quality building standard:
The building has basically two different sections: one is the centre with air condition and all other rooms are with natural air flow. The walls are made of burnt clay bricks (Uganda clays) isolation from the outside heat. The cold part of the building is made out of double walls in order to keep the cold inside the rooms. All floors are with special floor tiles and the walls with wall tiles. The inner height of the operating theatre room is 3 mts standard height in order to keep space for the special installations and head lamps.
Roof – partly a flat roof
The flat roof covers the higher part starting from the preparation room until the exit room. All auxiliary rooms are covered with a high quality corrugated iron sheet. Photovoltaic panels are covering the flat roof fully for supplying power to the cooling unit as well as the operating theatre battery system. Doors and windows: from Europe for a perfect closing and air tightness
Operating theatre ventilation system:
European standard ventilation system for operating theatre. The air pressure inside the operating theatre rooms is controlled and excess pressure does not allow inflow of dust from outside. Photovoltaic system: The proposed operating theatre is fully self-reliant, no need for the generator or any other power generation apart from installed solar array. The system is composed of 14400 WP solar field supplying 3 grid interactive inverters. For larger solar systems that generally supply to AC consumers, it is more efficient to immediately invert the solar power into AC. Therefore we call these systems “AC systems”. AC systems have higher energy efficiency in comparison to other systems. The Grid Inverter directly converts the solar energy into AC. All excess solar power which isn’t used by the AC consumers is used to charge the batteries.
The operation time in the operating theatre will depend on the scheduled and unforeseen emergencies within the hospital. Technically, electrical energy can only be harvested during sunshine, mainly between 8 am and 5 pm of a day. During this time, PV electrical energy can be used directly (light, ventilation, OP equipment, cooling compressors etc.) or can be kept in an electrical storage = battery. Cooling takes normally a lot of energy and therefore in the concept of this operating theatre, the cooling energy will be kept as cold water in a 5000 lts water storage under the floor of the operating theatre building. Night operations can be done without any need of electrical power for the cooling compressor / air conditioner.
Flicker free lights are foreseen for all rooms (energy saving)

Water and wastewater:
After independence from Sudan in 2011, peace lasted only a short period of time. Since December 2013, a civil war has been raging in the country. Simplified viewed, it is a conflict between two ethnic tribes.
Since 2011, around 18 Sisters of the organization DMI have been living in the region of Wau and in the capital Juba. They help to raise awareness for peace and reconciliation between the two tribes.
The off-grid PV-solar system was designed to enable the DMI sisters uninterruptable power supply. It consists of 48 solar panels, 10 stacks of Greenrock AIB solar batteries (of 48 Vcd 2.7KWh), a backup generator, solar charger, inverters and all required accessories for installation & grounding.
The old food store was modified in order to accommodate the batteries. AIB solar batteries were chosen as they are long lasting, environmental friendly and resistant to high outside temperatures.
The Power room is including:
All equipments were connected, programmed and tested in line with the regulation. The power outputs to the different buildings are through underground cables to the different buildings and all cables are marked for easy identification.
The centre was supplied with Grundfos submersible pump SQE 1-35 for constant water supply. The pump is controlled by CU 300 together with a Potentimeter for grundfos CU 300-SPP1 to control the flow in order control the water level. The initial PVC riser pipes were reused and the whole activity was successful.
The centre was supplied with a GENMAC Generator Urban RG8PS (8.0KVA-230Vac) as a back-up power supply for the solar system as well as for the centre on by-pass. The generator is set to automatic mode with the signal from the programmable relay of the victron color control GX. The generator was supplied with the most important spare parts.
The school is situated in Rumbek, Lakes State, in South Sudan. It is the world’s youngest nation that became independent in 2011 after a war with Northern Sudan.
Due to the ongoing civil war, started in 2013, many of the already insufficient educational infrastructures have been destroyed. There is a lack of schools, qualified teachers and materials.
In March 2018 the La Salle Brothers opened outside of Rumbek a Secondary School.
BBM delivered for the school a PV-system consisting of 110 solar panels of 300Wp, carefully mounted on special roof assembly with special Schletter roof mounting accessories supplied in the consignment. One of the classroom blocks nearest to the power house was selected as it was strong enough to carry the weight of the panels.
From left to right in the above picture, there is:
The equipment is mounted in one of the offices, on a steel plate which is secured on the metal structures of the prefab building.
This consists of 9 AXI storage Lithium battery sets of 10Kw connected in parallel in a Dc combiner box mounted on the wall as close as possible to the SMA inverters.
The school system consists of three Sunny Island, 8Kw inverter/charger that provide sufficient power for two water pumps and to the school buildings i.e Class blocks, Dormitories and teachers quarters. The Monitoring is done by Powerdog and using a tablet mounted next to the inverter/chargers.
This consists of two Grundfos submersible SQE 7-40 water pumps installed in two different boreholes to the East and West of the power house. The pumps have their controllers CU300 installed inside the respective pump chambers. The pumps supply water to locally welded tanks that have their main supply to the school linked so that they are drained equally. The power supply is controlled by photocell which stops the pumps from draining the battery during night hours.
The Loreto Primary Health Care Unit is the newest of the core programs at Loreto Rumbek.
The components of the care provided at the LPHCU include:
The Pv system consist of three sections which include:
The Pv power for the internal circuits consists of 21 Axitec solar panels of 300Wp mounted on the roof using schletter mounting materials. The system is connected through string connection boxes which have surge protection devices. The Cooling unit consists of 4 Axitec solar panels of 300Wp and 2 Victron Gel Batteries. The Pv power for pumping system consist of 7 Axitec solar panels of 300Wp.
One of the rooms in the health unit was taken up for the equipments to be installed. On the wall from left to right, Ac distribution panel, Victron Multiplus 48/5000/70 – 100 230 inverter/charger, lynx DC distributor (for inverter and solar chargers), two string connection boxes, Greenrock DC combiner box ( for the AIB batteries) and finally two Victron Blue solar MPPT 150/85 charge controllers
There are 5 stacks of Greenrock AIB Aqueous ion exchange batteries (salt water batteries) 48Vdc, 2.7Kwh each that are assemble at the corner behind the entrance door for this particular room. The advantages of this battery type are that they are environmental friendly (containing no hazardous materials) and they are resistant to high outside temperatures.
This consists of two independent sets of Steca solar fridge/freezer type PF240, 12/24Vdc powered from two Victron Gel 12V 220Ah Deep cycle batteries placed on a locally fabricated battery stand. Two batteries are connected in series for 24v system. The battery sets are charged independently through Victron Blue solar MPPT 150/35 charge controller and all Pv power are surge protected in the string connection boxes mounted next to individual charge controller. The two sets of batteries are monitored independently from Victron battery monitor BMV – 700 mounted on the box.
The cooling units were programmed for the intended usage. One is programmed for freezer mode for ice blocks and other items and one programmed for fridge mode for temperature 2°C to 8°C for vaccines and drugs.
The pump control system consists of the Grunfos IO 101 Control unit and Grundfos CU 200 and surge protection devices for the float switch signal line and the Pv power. The borehole in which the pump is lowered is about 25 to 30m from the building and a separate grounding for the pump was made. The pump was lowered down the borehole by local St Peter Claver students together with their instructors both electrical and plumbing. The required training was done to St Peter Claver training centre and the management staffs of Loreto School.
The installations were done using local students of St. Peter Claver training school and a solar expert from Uganda. After installation the system was commissioned in the presence of a BBM technician.
45 packages of bananas, filled with donations in all kinds. (Bed linen, towels and dishes) In summer 2019 the filled container left the port Hamburg into the direction of Mombasa in Kenia.
Furthermore goods like solar systems and water pumps were transported in the consolidated container.
Just before Christmas the container arrived in the Guest house in Rumbek after a truck route of 2100 km and a two week long trip on partly dirt roads. With great joy and a big thanks the donations were handed over to the team of the guest house.
The St. Daniel Comboni TB, Leprosy and HIV infirmary Marial Lou is located in the north of South Sudan in the administrative district Tonj East. The catchment area has in approximately the size of Upper Austria. The focus of the infirmary is on patients with highly infectious Tuberculosis, Leprosy and HIV. The infirmary has a bed capacity of 42.
The buildings are in a very bad condition and in need of a renovation. The infirmary has no own water supply but has an unusable fountain. For power supply they have a little generator, but the generator sometimes does not work and does not guarantee a continuously power supply. Furthermore they do not have a Beamer for showing videos about tuberculosis and their effects. Therefore they have a lack of health education and sensibility.
(7,5x bigger than Austria)
|Population density||19,45 inhabitants/km²|
The St. Daniel Comboni infirmary exists since 1994 and is one of 14 hospitals of AAA (Arkangelo Ali Association) in South Sudan. AAA is involved in the strengthening and improvement of life quality for pupils in undersupplied and difficult to access regions (e.g. Marial Lou) through provision of a free of charge health service, including TB-care, TB/HIV and Leprosy treatment.

Delivery from Austria in October 2019
Installation and Commissioning in December 2019
The project objectives at the Sisters of Loreto in Rumbek required both to provide the Sisters with an independent power supply and also to reduce the running time of the diesel generator.
The installation was completed in August 2011 by BBM experts. The photovoltaic system with 45 modules was mounted on two primed 20-foot maritime containers. The previously constructed battery room was converted into the power control centre, housing the new batteries (12 units, 2V cells) along with other equipment (solar charge controllers, power inverters, power distribution).
For the power supply of the office a smaller system (4 solar panels, 1 power inverter, 1 solar charge controller, 2 solar batteries of 12V) was additionally installed. This ensures that office routines can be maintained independent of the main system.
