Hamburg Wasser – Miyahuna LLC Water Company

Plant visits via video conferencing

German-Jordanian utility partnership gets going with an online meeting.

Miyahuna, Jordan’s largest water utility, and three German water supply and sanitation companies have entered into a long-term partnership to promote the transfer of know-how. Their objective: to reduce the serious water losses in the Miyahuna pipe system, make the sewage treatment plants more energy efficient and improve water quality management.


The project participants

International partner


Miyahuna, a public company owned by the Water Authority of Jordan, is responsible for water supply and wastewater management for around 760,000 people in the Jordanian capital Amman as well as in the governorates of Madaba and Zarqa and in part of Balqa Governorate.

Lead partner

Hamburg Wasser

Hamburg Wasser, the German lead partner of the project, is the largest municipal water utility in northern Germany. It supplies over two million people in Hamburg and the surrounding area with safe drinking water and reliable wastewater management services.

Co-lead partner


hanseWasser is part-owned by the City of Bremen and operates municipal and industrial sewage plants and wastewater systems. In recent years, work has focused on energy-efficient wastewater treatment processes and optimising the disposal of sewage sludge.


The project

Miyahuna and its German partners wish to sustainably improve the operation and maintenance of the water works operated by Miyahuna. In addition, they plan to increase the energy efficiency of  the sewage treatment plants while putting greater emphasis on renewables. The partners will also be looking at water quality management and providing support, primarily in the area of auditing, monitoring and benchmarking.

Energy-efficient operation of sewage treatment plants

Sewage treatment plants use a lot of energy, and this is very expensive. Miyahuna therefore wants to benefit from the experience gained by the German water utilities in reducing energy consumption and using renewables more intensively. In the first instance, this involves the transfer of know-how, as the transition to renewable energy would require large-scale investments and corresponding financing, for example via development banks. However, small-scale measures, such as changing aeration procedures in sewage treatment plants, can also produce results, and the project should focus its activities here.

Optimising processes at water works

The water Miyahuna supplies to its customers meets stringent quality standards. Nevertheless, there is still scope for optimising the operation of the water works. The project partners are looking at drinking-water filtration and want to jointly discuss how Miyahuna – with little extra work or expense – can provide clean drinking water, for example by modifying flushing cycles or flocculant dosage levels.

Water quality management

As part of its water quality management system, Miyahuna tests for various chemical and microbiological substances in drinking water and wastewater. These laboratory tests are conducted to ISO standards. To further improve Miyahuna’s water quality management system, various measures are planned: exchanges on quality and laboratory-related issues; support with audits, monitoring and benchmarking; and training courses.


As a result of the COVID-19 pandemic, the German partners have yet not been able to inspect Miyahuna’s plants and systems. For the start of the project, regular online coaching sessions are planned for small groups of experts. Creativity is called for: the partners could show details of their plants and systems via video calls and so compensate to some extent for the lack of face-to-face meetings.

Using diverse case studies, partners will be able to gain an overview of the specific areas in which cooperation would be most productive. A peer-to-peer approach will be important here, with those involved communicating on equal terms.

Comments on the project

“In our visit to Hamburg, I was most impressed that the sewage treatment plants generated more power than they consumed. In future, we at Miyahuna want to use all available and practicable options offered by renewables in order to improve our energy efficiency. This also includes biogas and solar energy.”
Haitham Kilani, Miyahuna, Amman, Jordan

“Hamburg Wasser has over 40 years of experience in international projects. For us it is important to help achieve the United Nations Sustainable Development Goals in the water sector – both in Germany and abroad. With this commitment, we are highlighting our attractiveness as an employer and offering our staff the opportunity to gain experience outside the normal work context.”
