R&d : PROJECT Mechanism of climate change and paleo climate Decision system (on GIS)for selecting an alternative solution Strategic tool for resources planning and development Complete the system with others data ( pipelines and others hydraulics infrastructure To put system on the web
R&D PROJECT : WATER RESSOURCES DEVELOPMENT AND CLIMATE CHANGE • The project outputs are:- A detailed paleoclimate of Morocco to understanding The mechanisms of groundwater recharge deep south of Morocco in the precipitation of Morocco does not exceed 100 mm.- Development of a climate prediction system based on global sytems (World clim, FAO Clim, NASA)- Development of a GIS water containing several thematic layers: spatial data, administrative boundaries, infrastructure, land use, satellite imagery, digital terrain models, Geology, Climatology, Hydrology, Hydrogeology

R&D PROJECT : WATER SUPPLY OF TANTAN USING BRAKISH WATER INSTEAD OF SEA WATER • The objective of the project was the feasibility study of using Brakish water (15 g/l) to supply the city of Tantan instead of using sea water desalination. • The project was conducted with EMI and consisted on Geological, hydrological and hydrological studies, completed by isotopic analysis long term pumping test.
R&D PROJECT : WATER SUPPLY OF TANTAN USING BRAKISH WATER INSTEAD OF SEA WATER
R&D PROJECT : WATER SUPPLY OF TANTAN USING BRAKISH WATER INSTEAD OF SEA WATER • The finding of the research is : • The large reserves of brackish fossil water in the Cretaceous basin constitute a real alternative, much more interesting than the desalination of sea water • This project has resulted in savings more than US $ 2.5 million in terms of investment and more economic in terms of operating • The solution is also environmentally interesting: - Less Brine - Less GHG Emission
Conclusion • ONEE as water utility is impacted by CC • ONEE’s strategy to cope with CC is based on • Demand Management • Use of unconventional water resources • R&D and capacity building • ONEE strategy is part of an overall government strategy for IWRM and CC
