As part of the World Bank project "Faecal Sludge Management: Diagnostic Tools and Guidelines for Service Delivery in
Poor Urban Areas" AKUT was commissioned in May 2014 with the implementation of surveys related to
faecal sludge management in Lima, Peru. These surveys are part of a worldwide investigation that takes place in
five cities on four continents.
This involves conducting a household survey (720 households) and focus group discussions, collecting and analysing faecal sludge samples and undertaking and documenting transect walks and field observations.
The project runs until September 2014.
Since October 2013 AKUT is active on behalf of GIZ in Brazil within the German Climate Technology
Initiative (DKTI). The project takes place until September 2015 and promotes the energetic use of biogas in the
The project supports the Brazilian energy planning authority EPE (Empresa de Pesquisa Energética) in the analysis of the biogas potential in Brazil, as well as in the identification of successful biogas business models for and barriers to the economic utilisation of anaerobe technologies, so that this information can be used for key stakeholders in the biogas sector. Throughout of the project four pilot and demonstration projects will be initiated.
Information on energy demand and gas potential of the systems is required in order to improve energy efficiency and the energetic use of biogas in sewage treatment plants. To determine the biogas potential and to develop proposals for future wastewater treatment projects a measurement campaign at ten selected wastewater treatment plants will be carried out.
AKUT has elaborated in the working group ZUSIE together with the engineering firm Prof. Dr. Sieker mbH,
Hoppegarden and the Water Department of the Faculty of Agricultural and Environmental Sciences, University of Rostock an
expert report on regional development scenarios about urban water management considering the conditions of demographic
change in the state of Brandenburg.
Safe drinking water supply and sanitation are very important aspects of the general public services. With this study the administration, the municipalities and the public should be made aware of the possible consequences of demographic change. The consequences for the expenses, the financing and the organization of water supply and sanitation are to be developed as part of a process model.
The summary of this study from November 2013 is published on the website Leitbildsiedlungswasserbb.de.
The first stage of extension of the Finlays CHP Biogasplant started working in April 2014 in Kericho, Kenya.
Customer is Finlays an international company, principally focused on tea, but although on rubber, flowers and fresh produce in Africa and Sri Lanka.
The plant is designed to use waste from flower and tea production and slurry from septic tanks. The first stage is laid out to substrate feeding of about 28 to per day with electrical installation of about 160 kW. About the same amount of heat will be used to pre-heat the water for steam-production. Extension will be for 70 to per day with electrical installation of about 600 kW.
Beside the production of electricity to stabilize and support the local grid the plant will avoid the emission of greenhouse gases like methane from dumping waste. Together with the use of the digested slurry as fertilizer in the wood production (closing loops) the plant aims to contribute to Finlays sustainable development goals like ‘zero net impact’ as minimum environmental standard.
AKUT stepped into the project from the very beginning (in 2007) with a feasibility study followed by a trial for digesting the specific wastes (2008–2010). Based on these results and according to the Kenyan specifics on construction prizes the design and the final calculations were done in 2013. Also in AKUT organized a training program in Germany for the two designated operators of the plant.
At the end AKUT was also responsible for the delivery of machinery and pipes, supervision of construction and put in operation. Now support for first period of operation starts April 2014.
The digester is constructed as combination of lagoon with about 22 m diameter and ring wall out of reinforced concrete. In total the depth is at 7 m and the filling level at about 6.30 m. The lagoon and the walls are sealed with a fabric reinforced PE-foil. The digester is covered with a gas tight plastic membrane; air inflated for protection against heavy rains and wind and integrated gas holder.
All technical equipment is located in a single 20' container: pumps for mixing and feeding, equipment and panels for measurement and control, the compressor for pressurized air, the register for hot water of heating system, the distribution register for feeding and transport pipes, heat exchanger, compressor systems and electrical supply devices. Moreover the control system is automated.
For using the gas a new efficient biogas dual-fuel CHPS is implemented. The CHPS is preinstalled in a container. The electrical energy will be fed into the internal grid. Some of the thermal energy will be used to warm up new substrate and to maintain the temperature of the digester. A heat-pipe will be laid to the nearby Tea-factory to use the rest for pre-heating water in the Central Steam Station.
Feeding is done with a central feeding pump following a substrate conditioning with crusher and septic slurry storage.
Feeding devices are already prepared for extension to full capacity, so it will be easy to go further with the digester 2 3 4.

Since December 2012 AKUT is part of a PPP-Project for rainwater collection in Morocco:
"Rainwater Harvesting in Tidhreste, Morocco"
The project is conducted in cooperation with the Berlin landscape planning office Schulze und Matthes, the local association AED and GIZ.
The objective is the development and introduction of methods for rainwater collection in conjunction with measures for the prevention of erosion.
To be used are systems for rainwater collection, such as terraced collection areas and mini-reservoirs, the so called Negarim, which enable targeted soil moisturising in the form of water storage and erosion prevention, as well as systems for the collection of water on the sole of dried-up water courses, called Oueds. For the irrigation systems particularly resource-saving technologies will be combined with traditional practices. As a result all participant local partners should be able to plan and build such systems on site.
The project has a duration of two years.
Since June 2012 AKUT is active on behalf of GIZ in Nicaragua.
The aim of the TC-project is to improve the energetic efficiency of the water supply and sanitation systems. The main focus will be the institutional strengthening of the national water supply and waste water disposal company Empresa Nicaragüense de Acueductos y Alcantarillados (ENACAL).
AKUT is responsible for improving the organisation, the main operations and cost structure of the two branch offices of ENACAL in Boacco and Chontales.
In addition to increasing the service quality (supply duration and customer service), the project it also about establishing a system of result-oriented and effective planning, monitoring and evaluation tools, as well as the introduction of standardized processes and procedures (SOP).
In order to cover the operation costs the following aspect are to be implemented: reduction of physical water losses, reduction of energy costs and increase of revenue by developing and maintaining a customer register.
The project has a duration of two years.

On 27th Oktober 2009 took place the inauguration of the new waste water treatment plant in Friesen, Reichenbach.
The waste water is collected in a combined sewer along the Friesener Berg. It consists of domestic waste water and rain water, which is collected on sealed surfaces and does not seep away on-site.
The method Phragmifiltre ® was developed in France by SINT and CEMAGREF for highly contaminated waste water. The use for treatment of combined waste water is an innovation in Germany.
Take a look at the first treatment stage on the plant:

"Sure thing - Spree should be cleaned" is the headline of the Berliner daily newspaper "Der Tagesspiegel" on 15th Mai 2008. The pilot module of the project SPREE2011 will be built from autumn 2008, to be lowered into water early 2009 at the Berlin East Harbour, writes Tagesspiegel.
AKUT is one of the partners in the research project SPREE2011, supported by the Federal Ministry for Education and Research. The aim of the project is the construction of a pilot plant for the storage and treatment of waste water directly into the river Spree. The plant is to be built in 2008 at the Berlin East Harbour. Using tanks fixed at the bottom of the river to catch the overflow from the combined sewer system in the case of heavy rainfalls, this will be pumped into the treatment plant. In the long term this and other measures will lead to an improvement of the water quality in the sewage network. Other participants are LURI.watersystems.GmbH and the TU-Berlin, with Prof. Dr.-Ing. Matthias Barjenbruch. AKUT conducts the technical consulting and planning services. The project runs until April 2010.
At the beginning of 2007, AKUT, in co-operation with ARGUS Berlin, took over a branch of the
continuing education program "The politics of sustainable energy". There were a total of 23 participants
from Latin America.
The client is InWent - International further education and development gGmbH. Within the framework of the field, strategies for safeguarding the sustainable energy supply of Germany and the EU were presented.
The use or regenerative energy and renewable raw materials were discussed and the basic technical and political conditions for their appropriate use were demonstrated.
The program was completed on 27 July 2007 and the participants were presented their certificates by Mr. Bernd Schleich, the manager of InWent gGmbH, and Mr. Volkmar Strauch, the state secretary of the administration for economics, technology and women.
AKUT was awarded the title "Climate protection partner" in the category
"Successful projects" for the second time on 8 May 2007. The ecological reconstruction of the
Franciscan Monastery in Berlin-Pankow was awarded.

The title "Climate protection partner of the year" was awarded for the 6th time this year. The "Climate Protection Partners" in Berlin is an amalgamation of 14 associations and institutions in Berlin. They nominate and award projects that contribute to Climate protection and use intelligent and flexible technology.
In March 2007 several participants in the InWent-continuing education "The politics of sustainable energy"
went on an excursion organized by AKUT.
The photo shows the participants in discussion with the biogas farmer, Ebeling, at the biogas farm in Wendland.
In January 2007 AKUT was present at the International Organic week in Berlin.
In co-operation with the Planning Agency for Biogas Technology and Krassuski Project Management, the booth served to inform the public about biogas facilities and advertise the optimal use of the facilities' waste heat.
Since January 2005 AKUT has been commissioned by the Association for Technical Cooperation (gtz) in Kenya. The project, which is going to be run until the end of 2007, serves to reutilize waste and sewage flow from agricultural production facilities and supply management of the treatment and processing of agricultural products. In this way, along with the reduction of environmental pollution that results from process streams, an additional source of income is produced for the farmers and production operators. The specific aim of the project is to work out reutilization concepts for specific plants/ farms, as well as to provide training toward constructive implementation of this concept at Kenyan engineering offices. The company Fa. Krieg & Fischer Ingeneers GmbH, Göttingen, is our competent partner in the anaerobic reutilization of wastes and sewage (Biogas production).
AKUT was commissioned to set up a turn key sewage treatment plant for the community of Albondón, Granada. The client is Aguas y Servicios de la Costa Tropical de Granada. A two-stage soil filter is implemented. The concept is based on the successfully implemented soil filter introduced in France by Société d'Ingénierie Nature & Technique, which functions without pre-purification. The raw sewage, containing solid matter is filtered in the first stage. By alternate loading, drying and mineralisation of the settled sludge is reached. The continued purification of the sewage follows in the second stage. The advantage of this process over the conventional plant-growth-purification method is that less ground area is used. Because of the hydraulically ideal location, a dovetail layering with the help of lift jacks is made possible. Thanks to a solar-driven automatic screen from Contec, no external energy is needed at the Albondón plant.
Since March 2004, AKUT, by order of the Association for Technical Cooperation (gtz), has been responsible for the consulting of the Peruvian cities, Puno and Huancavelica, on water supply and sewage disposal. The consulting contract was completed in 2006. AKUT's approach is refined by the exchange of experience with two similar plants in Argentina. As a competent partner, we enabled the first privately run supplier of drinking water and sewage facility in Argentina, LatinAguas, to be established.
