Treatment Ponds and Lagoons
Ponds and lagoons have been used for hundreds of years and for a variety of purposes. In ancient times, organic wastes were intentionally added to ponds to stimulate the growth of algae, which acted as a food supply to increase fish populations for harvesting. Initially, the first wastewater collection systems simply discharged wastes into the nearest body of water. The volume of wastewater increased as populations increased, and clean water bodies were negatively impacted. The need to isolate wastewater from other water sources became apparent. Therefore, treatment ponds were created to protect clean water sources by separating wastewater.
