Abandoned pools tend to be unattractive and may smell bad. They also act as inadvertent rainwater harvesting devices, with a small, algae-laden puddle in the deep end. Without chlorine and filters, the water in an abandoned pool becomes an ideal mosquito breeding ground.
These mosquitoes are not only a nuisance to the homeowner and their neighbors, but they can carry serious, even life-threatening illnesses like Zika and West Nile. In addition, abandoned pools may attract snakes and other creatures. Droppings from these creatures and birds can also breed disease.
Thus, a major benefit from filling an abandoned pool is removing a public health hazard. The financial benefits of removing an abandoned pool include reduced homeowners insurance and lowering your property taxes. You also get the benefit of making your yard safer for children, vulnerable adults and pets, as well as freeing up the space for other uses.
