The rainwater is filtered by the limestone rooftops and generally stored in an underground reservoir. Then, to bring a water supply inside the home, pump them to overhead tanks. Bermuda's yearly rain fall is sufficient to provide residences with a year-round water supply while also sustaining the island's beautiful green flora. There are two main water companies that serve Bermuda: Bermudagreen and Blue Mountain. Bermuda's green landscape is due to its heavy rainfall, which provides much of the island with its freshwater supply. Limestone soils filter some parts of the water table before it reaches bodies of water such as bays and oceans where it becomes saline water that cannot be used for drinking. However, if you live near a freshwater source such as a river or lake, you can use that water instead! Bermuda's unique climate requires residents to take certain precautions when out hiking or biking in the wild. Because of the high humidity and the need for air conditioning in most homes, it's not recommended to go without clothes in Bermuda. Also, because of the risk of falling into natural holes in the ground, it's important to keep an eye on your children while out in nature. Finally, bear attacks are not common but they do occur so please use caution when walking through wooded areas. In conclusion, Bermuda has a water supply system that depends solely on rain for its survival.
