World Water Day 2023 – Accelerating change to solve the water and sanitation crisis

Water distribution networks play a critical role in protecting the resource of drinking water. Drinking water is a scarce resource, and it is essential to protect it from contamination, pollution, and overuse. A safe and adequate water distribution network is designed to capture, treat, and distribute water from the source to the end-user, while minimizing the risk of contamination and waste. This is essential to protect public health and prevent the spread of waterborne diseases.

Well maintained water networks are also crucial for the sustainable use of the resource by ensuring that water is delivered efficiently and that losses are minimized. This is achieved through measures such as leak detection, pressure management, and water metering, which help to reduce the amount of water lost through leaks and unauthorized use. Finally, water networks are essential for ensuring that drinking water is accessible to all members of society. This includes safeguarding that water service is affordable and that households have access to safe and reliable water sources, regardless of their location or socio-economic status. In conclusion, water networks play a critical role in protecting the resource of drinking water. For us the water and sanitation crisis is a complex and multifaceted challenge that requires a collaborative effort from all stakeholders. We believe that an essential component of solving the water and sanitation issues is connected to functional water networks. Therefore, we are proud to be of service to local communities and state agencies during their efforts to construct new and/or to rehabilitate existing water networks.

World Engineering Day 2023 – Engineering Innovation for a More Resilient World

Inhambane and Maxixe are two cities located in the Inhambane Province of Mozambique, and they are highly vulnerable to the effects of storms, flooding, and sea-level rise due to their coastal locations. The goal of the project is to develop a comprehensive plan for these cities which will improve their infrastructure and provide protection from the effects of these natural disasters.

Our services include an analysis of the existing infrastructure and systems in place in both cities, as well as a review of the current coastal protection measures. In addition, we are conducting a detailed assessment of the social and economic impacts of the proposed coastal protection measures. The project considers developing economic opportunities and stakeholder participation. The study will provide to our client a comprehensive plan for the implementation of the proposed coastal protection.

International Day of Education – Malawi Education Joint Fund Project

Following heavy rains, floods and hurricane winds over the past years in Malawi around one million people were affected with deaths and injuries in large number reported. The global warming and climate change have contributed to the returning disasters and have triggered significant damage to Malawi’s educational infrastructure including public primary schools, teachers’ houses, furniture and textbooks. Where buildings were left standing, many classrooms were converted to shelters for approx. 90,000 displaced people, whose homes had been swept by the floods.

To restore effective teaching and learning in the affected areas, CES Consulting Engineers is supporting Malawi Government to rebuild school facilities with an emphasis of “building back better” with new more resilient structures and WASH facilities more responsive to the safety needs of boys and girls with financial support funded by the German Financial Cooperation through the Education Services Joint Fund.

CES wins FIDIC award for Outstanding Project of the Year

At a gala dinner event held in Geneva on 12 September 2022, the International Federation of Consulting Engineers FIDIC announced the three winners of the Award “Outstanding Project of the Year” in the three categories small, medium and large. Our Managing Director Dr.-Ing. Ralf Meyerhoff participated on behalf of CES and had the honour of receiving the coveted trophy for small projects.

Despite the seamless and highly successful implementation of the project and the great impact it had on the beneficiary population, the award came a bit as a surprise, as Project Director Matthias Fritz pointed out: “The project is not a typical civil engineering project and we prevailed against major international competition. Usually, prizes go to major infrastructure projects such as bridges, airports or tunnels. In our case, however, the special challenges in the context of international cooperation were recognised. The achievement of the UN Sustainable Development Goals has also become especially prominent.

Indeed, this year’s 28 shortlisted projects were covering all the 17 SDGs goals across a significant range of project values.

FIDIC CEO Dr. Nelson Ogunshakin emphasized during his speech: “The strength of this year’s winners is a testament to the enduring excellence of the work of consulting engineers and the value that our industry brings to society by delivering excellent construction and infrastructure projects that transform people’s lives.”

Sustainable Land Management in Somaliland is a project to save the Biji catchment area from erosion, and to improve rainwater harvesting and storage of water for drinking, food security and livestock. This catchment area links to aquifers that represent the main water resource for the region’s population, making recharge of these aquifers a vital aim.

Being financed by the BMZ through the German development bank KfW the project was implemented by CES in close cooperation with the client, the Ministry of Agricultural Development. As the national construction companies worked for the first time with FIDIC contracts, CES provided permanent training contributing to a remarkable strengthening of national construction capacity. Furthermore, the challenges in this project arose less from engineering issues than from the management and implementation of the measures, taking into account local and especially social conditions: The determination of type of measures, construction method and materials, location and number required a high level of coordination with local ministries and the rural population as final beneficiaries. The involvement of all stakeholders throughout the project cycle resulted in a high level of acceptance, which was necessary to sustainably improve living conditions in the region.

For us at CES, this award is a major achievement that we are very proud of, but at the same time another spark of motivation to continue giving our best effort for the improvement of living conditions through our infrastructure projects.

We would like to thank the entire CES team, all project participants, in particular the team of the Ministry of Agricultural Development and KfW for the trust we received when implementing this outstanding project.

A detailed description of the project in Somaliland can be found in this article:


The warming stripes are a visual representation of how temperature has changed in locations around the world. They were created by Ed Hawkins, a climate scientist from the University of Reading in the UK. He also created the „warming spiral“ graphic that was used during the closing ceremonies of the Rio Olympics. Each stripe represents a year. Blue means it’s colder than average. White means it’s about average. Pink means it’s warmer. And red means it’s a LOT warmer!

World Water Day 2022

Groundwater provides almost half of all the drinking water worldwide, about 40% of the water for irrigated agriculture and about 1/3 of the water supply required for industry. It sustains ecosystems, maintains the baseflow of rivers and prevents land subsidence and seawater intrusion. Groundwater is a key resource for the achievement of the UN Sustainable Development Agenda for 2030 (UN Water). At CES, the responsible use and protection of groundwater of groundwater is deeply embedded into our understanding of implementing sustainable water supply, wastewater and hydraulic engineering projects.

Water related projects are the core competence of CES. The following examples of our ongoing worldwide projects cover the complete water cycle:

Irrigation Improvement Project (PACT II) in Tungurahua Ecuador and new Branch Office of CES in Ecuador

The project’s objective aims to achieve the modernization of irrigation systems, as well as other measures for the protection of the water resources of the province. The sustainability of the investments is intended to be achieved through the involvement and technical assistance of beneficiary groups and organizations and the establishment of sustainable marketing chains.

Tungurahua is a province with very fertile and productive lands, because of the influence of the volcano with the same name. Agricultural lands cannot be cultivated without supplementary irrigation, which farmers apply mostly in the traditional way by gravity.

Since the available water in the natural sources is no longer sufficient to irrigate all area, the provincial government promoted the change to more efficient pressurized irrigation methods since 2010. During this first phase of the project with assistance of CES, a smart methodology was developed to transform gravity irrigation systems to pressurized irrigation, through which the irrigation area was doubled without increasing water extraction from the sources in the vulnerable paramos.

Beneficiary in the Tungurahua province

The very promising results of the pilot phase led to the extension of the project with the now started second phase comprising pressurized irrigation of 2000 hectares from 4000 farmer families. The project is financed by the German Ministry for Economic Cooperation and Development (BMZ) via KfW Development Bank with 19 million Euros and contributions of €3.5 million from the province and €2.5 million from the beneficiaries.

Successful Completion of the Primary School Programme in Niger

Quality Education is one of the Sustainable Development Goals of the United Nations. Education is a key factor to escaping poverty. Despite progress made in the last decade, nearly one fifth of the global population in the relevant age group has no access to schools. The ongoing COVID-19 pandemic now jeopardizes hard won gains made in improving global education.

In this context it is even more important that in Niger, one of the poorest countries worldwide, more than 200 new classrooms could be handed over to the beneficiaries despite the pandemic in the final stage of the construction.

SDG 4: Quality Education
