Lebanese drawing of Wazani River waters, which stream into the Israel-bound Hatzbani River, could begin as early as next week. The Lebanese have completed placing the appropriate piping, and construction of the water-pumping installation was expected to begin today. Defense Minister Binyamin Ben-Eliezer, visiting the north yesterday, said that the new plant will take 10% of the water bound for Israel. Agriculture Minister Shalom Simchon echoed previous remarks by Prime Minister Sharon, saying that Israel could not accept Lebanon's diversion of the water.
