Septic tanks are a form of on-site wastewater treatment. That is, if you have a septic tank, you are treating sewage in your backyard instead of sending it through the sewer system to be treated at a sewage treatment plant.
Septic tanks – even when working properly – do not function well in South Florida. Septic tanks are a threat to both public health and the environment. In particular, septic tanks contribute to nutrient pollution – a type of pollution that occurs when too many nutrients accumulate in our waterways, leaving the waterways vulnerable to algae blooms and fish kills.
