Rain can also be collected in man-made reservoirs. A reservoir is like a very large bowl. The reservoirs benefit from all the nearby hills that can make the level of a reservoir rise by 3 or 4 inches when the rainfall has only been 1 inch. Anne Arundel County draws water mostly from underground aquifers and deep wells. We have 58 wells that supply water to our Treatment Plants.
Water is purified by many different processes.
Anne Arundel County has 12 Water Treatment Plants to protect us from diseases and to supply water for drinking, bathing and fire protection. Clouds are made up of evaporated water. The clouds will hold the water as long as they can, then it will rain. These tanks ensure water pressure and water volume are sufficient to fight fires even during power failures. They also provide an extra source of drinking water during the day when water use is high.
