Final workshop on rainwater harvesting in South Morocco

Final workshop on rainwater harvesting in South Morocco

A circular path has been completed in order to present measures for strengthening the agricultural sector in the region Souss-Massa-Draâ in December 2015. Rainfalls are less frequent and single events often heavier in these oases that are highly affected by climate change.

Due to poor and infrequent water supply traditional agricultural activities have declined significantly and heavy rainfall events are cause of erosion in many areas. A combination of various decentralized and small-scale measures was set up to improve the situation. One example is the construction of several ground sills / small dams that have been built in the long branched valleys above the oasis Tidrheste to reduce erosion.

Water retention measures increase the infiltration rate and usable water is directed into small channels. As a result of the collection of water in Negarim microcatchments and decentralized cisterns the olive tree cultivation is now possible without usage of (scarce) groundwater.

The successful international cooperation of AKUT Umweltschutz Ingenieure Burkard und Partner, Schulze-Matthes Ingenieure, the Association Ennacer de Développement (AED) of Tidrheste and the GIZ shall be continued. Further information about the project, irrigation, erosion protection and Rainwater Harvesting in arid climate zones may be obtained from Heribert Rustige.

AKUT optimizes energy efficiency of water supply systems in Brazil

AKUT is part of the developing team to establish Berlin`s central river pool

The 1,8 km long river arm “Kupergraben” in Berlin’s central district will be awakened after a deep sleep. The river arm will undergo renaturalization measures and parts of the section between Fischerinsel and the Bode Museum will be used as a swimming pool. The conversion will revitalize this UNESCO World Heritage Site as one of Berlin’s historic lifelines whilst the ecological rehabilitation of urban waters yields the way to a general sustainable urban transformation.

AKUT is assigned to draft and plan a pilot plant for a treatment of the river waters in a constructed wetland. AKUT will work on this assignment in cooperation with Dr.-Ing. Pecher und Partner Ingenieurgesellschaft mbH and Kompetenzzentrum Wasser Berlin gGmbh.

Final dimensioning and site-specific adaptions will be possible after different filter types (constructed wetlands) are analyzed in the pilot plant. Starting off with the construction of the plant in the first half of 2016, sampling and optimization is going to terminate in the end of 2018.

AKUT optimizes energy efficiency of water supply systems in Brazil

On behalf of GIZ in Brazil AKUT is commissioned to develop a new framework for improved energy efficiency in urban water supply systems.

Water resources management in Brazils is one of the sectors with a energy demand in relation to other public services. The water supply system is characterized by low efficiency. Supply systems are mostly outdated and in ailing condition.

The project is structured into four fields of activities: (1) support of the Brazilian Ministry of Cities (MCid) in developing new funding instruments with the goal of energy efficiency; (2) organization of interinstitutional and intersectoral dialogues; (3) Elaboration and application of technical and economical energy efficiency instruments   and measures and (4) Extension and qualitative improvement of consultancy services for the water management sector concerning energy efficiency.

The project timeline is scheduled from beginning of 2016 until the end of 2018. AKUT has organized a close collaboration with the swiss engineers “Skat Consulting AG” (specialized on energy efficiency measures) and the Portuguese Laboratory for Civil Engineering (LNEC, Laboratório Nacional de Engenharia Civil) whose experience in the national initiative for loss control (iPerdas, Iniciativa Nacional para o Controle Eficiente de Perdas) will be essential for the success of this project.
