Hebrew University, pt2

Our next visit on Tuesday was to the Shafdan Rishon Wastewater Treatment Plant. The world's largest wastewater treatment plant, the Shafdan plant treats almost 500 million cubic feet of water annually - serving a population in the Dan Region (which includes Tel Aviv) of over 2 million people. Operated by Mekorot, this plant's reused water is transferred in large quantities to the agricultural regions in the Negev.

As we came to find out during the tour - Israel reuses almost 75% of their water. The next closest country is Spain at 12%. The USA only reuses a little under 1% of our water. What makes these figures the most appalling is that most wastewater is 99.9% water, and only 0.1% waste. We obviously have a lot to learn from Israel in terms of water management.

On Wednesday, the team had a final class with Dr. Gilad Axelrad, another professor in residence at the School of Agriculture. Over about two hours, Dr. Axelrad discussed the various innovative structures for creating partnerships between government and private industry in order to address public infrastructure projects. Following this class, the team was accompanied by Dr. Axelrad to Palmachim Desalination Plant - the second largest desalination plant in Israel - and one of the largest desalination plants in the world. Our on-site host at Palmachim was Avram Tenne the head regulator for water plants in Israel.

The visit to the desalination plant was for me the most interesting of the water company visits we had while at Hebrew University. As we had at the previous facilities, we were given a full tour of the plant, seeing the entire operation from start to finish. At the end of the tour, we got to taste the end product (i.e. purified salt water) which had been in the ocean only 20 minutes previously. Interestingly, the taste wasn't quite what I expected - apparently having to do with the fact that many minerals that are normally in drinking water hadn't been added back yet. Still it was very cool!
