Stiftelse CSDI WaterTech is a non-profit research foundation established in Norway in 2015. It operates as a Centre for Sustainable Development and Innovation of Water Technology (CSDI).

Our goal is to contribute to safer society and better quality of life through sustainable and innovative development and dissemination of water technologies in the areas of Storm water management, Renewable energy, Environment technology and Rehabilitation of ecosystem services and repairing and rehabilitation of concrete hydraulic structure by using robust materials. The goal of CSDI will be achieved through close collaboration with universities, research institutes, public and private sectors in Norway, Europe and developing countries in the world. Coordination and participation of EU and national R&D projects is one of our major activities.

Role in the project:

CSDI’s main tasks in this project is to develop a Rainwater Harvesting (RWH) unit for the replenishment of the water supply of the textile closed-loop wastewater recycling plant through collaboration with the other partners. ERAK is the demonstration site. Key project tasks for CSDI include:
Participate in Task 2.2. Review of ERAK factory requirements. A statistical analysis based on the historical rainfall data from the gauged stations in the catchment area will be performed in order to know how much rainwater is available for the Rainwater Harvesting (RWH) subsystem.
2). Lead Task 4.8 Develop Rainwater harvesting subsystem. In this task, we will use technical specifications from WP2 to design and develop an adequate rainwater harvesting unit that will be integrated into the large-scale Waste2Fresh system prototype to enable the use of rainwater (or fresh water added to the system provided rainfall does not coincide with ERAK device) to demonstrate the prototype system at ERAK. A process simulation model covering all process steps will be developed in combination with rainfall analysis from WP2 to inform the size of the rainwater and the operation condition of the RWH subsystem vis-à-vis the operation of the overall closed-loop system. A conceptual approach of the RWH unit and fresh water or potential wastewater recycling is illustrated in Figure 1.

Relevant Projects:

Integrated urban storm water management, urban hydrology, hydraulic modelling and development of sustainable urban drainage systems are our central areas. Focuses of our recent research projects and other activities are on the assessment and adaptation of climate change and urbanization impacts, while reducing of flood risk, increasing rainwater reuse when it is appropriate, protection and improvement of water environment and rehabilitation of urban ecosystem services by the implementation of sustainable green solutions. CSDI key participants have experience in national, bilateral and international R&D projects, such as:

  1. EU-FP7 PREPARED (2010-2014): Enabling urban water and wastewater system to climate change.
  2. EU-FP7 FloodProBE (2009-2013): Technologies for Cost-effective Flood Protection of the Built Environment.
  3. EU-FP7 PEARL (2014-2017): Preparing for Extreme and Rare Events in Coastal Regions (PEARL). EU-FP7 project.
  4. Water JPI RainSolutions (2019-): Research-based Assessment of Integrated approaches to Nature-based SOLUTIONS.
  5. Development of technical guideline of stormwater management in local areas and design of different measures for infiltration and detention or storage of rainwater for flood mitigation and /or for reuse, e.g. SINTEF Byggforskserier 311.015; 514.114.
