Drinking water supply in prosperous water shortage regions (TRUST)

Drinking water storage in a village in the Peruvian Andes

In the BMBF joint project TRUST, new planning tools as well as integrated water supply and wastewater disposal concepts were developed together with experts from various disciplines using the example of the Lima/Perú region.

In the joint project TRUST, TZW developed new planning tools and integrated water supply and waste water disposal concepts together with experts from various disciplines, using Lima/Peru as an example. This region is representative of many areas with water shortages around the world. An additional challenge for sustainable water resource management was the inadequate database on the quantity and quality of waters. The work in TRUST should help to achieve the sustainable development goals for water set by the United Nations (Agenda 2030).

TZW created the database in the collaboration with the Institute for Water and River Basin Management (IWG), the Institute of Photogrammetry and Remote Sensing (IPF) (both KIT), the company OTT and local stakeholders. This culminated in a decision-making support and risk management system for water suppliers developed by TZW and disy. The catchment area of a reservoir in Saxony served as a test area to develop the methods and to investigate the transferability of the results with the Landestalsperrenverwaltung Sachsen (Reservoir administration of Saxony).

Together with the Institute for Sanitary Engineering, Water Quality and Solid Waste Management at the University of Stuttgart (ISWA) and the engineering firm ipp, water supply and water recycling, TZW developed concepts to use the available water resources as efficiently as possible.

The ZIRIUS institute at the University of Stuttgart coordinated the project and identified the actors in the Peruvian water sector as well as possible conflicts of use. Together with the consulting firm decon international, the project partners developed training measures and further opportunities to disseminate the project results.
