Diseases That Commonly Arise if Tanks Are Not Cleaned Regularly

Bird droppings, debris, dust, dead animals, and twigs from nearby trees can easily make their way into your rainwater tank.

And if you do not clean your rainwater tank regularly, this debris can spread the growth of some very harmful bacteria and parasites. Using such contaminated water can often increase the risk of health diseases.

Still not convinced about scheduling regular tank cleaning?

Here are some diseases that contaminated water from unclean tanks can cause and their effects to make you reconsider.


Salmonella infections are a type of bacterial disease of the intestinal tract. Symptoms of an infection may include nausea, diarrhea, fever, abdominal cramps, vomiting, and headache.
