Effluent Reclamation as a Sustainable Solution Eng. Yossi Shmaya – District Manager International Seminar “Water & Effluent Reuse” Sao Paulo, Brazil, March 19, 2013 The Mekorot Group Effluent Reclamation as a Sustainable Solution Mekorot – Facts and Figures Revenue Supplies 80% of 1,200 Water $1 billion per annum drinking water in Israel well drillings Investments Supplies 70% of total 3,000 Facilities $350 million per annum water consumption Employees Reuses 60% of Israel’s 12,000 km of 2,400 treated wastewater water lines Effluent Reclamation as a Sustainable Solution Mekorot Supplies 70% of all Water in Israel Brackish Desalinated Effluents 12% 16% 22% 50% Fresh Water: Sea of Galilee & Aquifers 1.5 Billion m3 water per year Effluent Reclamation as a Sustainable Solution Mekorot – A One Stop Shop Water Desalination Quality Water Water Supply Treatment Water Command Security & Control Rain Operational Enhancement Models Wastewater Hydrology Treatment & & Drillings Flood Reclamation Catchment Effluent Reclamation as a Sustainable Solution From Vision to Reality “In order to be a realist in Israel, one needs to believe in miracles” - David Ben Gurion, Israel’s first Prime Minister Effluent Reclamation as a Sustainable Solution The First Innovative Solution Effluent Reclamation as a Sustainable Solution 1. The Arava Region A desert and arid region Remote and disconnected from national water systems Low water quality requires complex water treatment The national water carrier 65% of Israel’s vegetable export comes from the Arava Arava Region Effluent Reclamation as a Sustainable Solution The Negev Region 30% of Israel’s agricultural crops are grown in the Negev Region (desert area) using effluents Effluent Reclamation as a Sustainable Solution 2. Desalination – The Water Revolution in Israel 2014 75% 2010 30% 2004 The National 3% Water Carrier In 2014, 75% of the drinking water will be from desalination facilities Effluent Reclamation as a Sustainable Solution 3. Water Loss Mitigation Average Water Loss: Developing countries 35% Developed countries 15% Israel 10% Mekorot 3% Effluent Reclamation as a Sustainable Solution 4. Energy Saving & Efficiency Mekorot has reduced its electricity costs by 1.5% in each of the past 20 years by: Reducing energy loss in water transmission systems Using advanced command and control systems and operational models Integrating renewable energy technologies Effluent Reclamation as a Sustainable Solution 5.
