Water storage tanks can often be exposed to extreme sunlight which encourages algae growth. This quickly leads to polluted water that cannot come in contact with a human or an animal without causing harm or sickness. This would include everyday applications such as drinking, washing the clothes, playing in sprinklers on a hot summers day. The bottom line is, once algae grows in your water storage tanks, the water basically becomes useless if you are a long way from a water source.
Water storage is becoming more and more important to the environment. Water is the most important natural resource we have, so harvesting and storing rainwater to preserve it, is a must. One of the most common problems you will run into when storing rainwater is the algae growth in water tanks . The presence of algae growth in water tanks will make your harvested water nearly unusable. Algae is a bacteria that can carry toxins that are harmful to animals, humans and plants.
