Water Storage Systems This is the VOA* Special English Development Report. Each year, millions of people in Bangladesh drink ground water that has been polluted by naturally high levels of arsenic poison. Finding safe drinking water in that country can be a problem. However, International Development Enterprises has a low-cost answer. This nongovernmental organization

ensures it can provide highly-efficient transport links. To capitalize on these geographic advantages, Saudi has set itself three strategic targets: * to become the global capital of energy. Up and downstream petrochemicals, minerals, power and water are all vital to the Saudi and global economy. * to act as a transport and logistical hub between east and west. KSA’s roads, railways and air links create a potential consumer base of more than 250 million, all within 3 hours’ reach. * to

Almost the entire Israeli increase in the demand for fresh water since 1967 has been met by pumping in water from the Occupied Territories

of the systems which can lead to waste disposal issues. Re-circulating aquaculture needs to have excess nutrients removed from the system, normally this means that a percentage of the water is removed, generally on a daily basis. This nutrient rich water then needs to be disposed of and replaced with clean fresh water. While re-circulating aquaculture and hydroponics are both very efficient methods of producing fish and vegetables, when we look at combining the two, these negative aspects are turned
