| Description |
The Lake Cannon Urban Wetlands/ Alum Injection Stormwater Treatment Feasibility Study was started in 1991. The report completed by Environmental Research & Design recommended construction of an alum injection system for the treatment of stormwater discharges entering Lake Cannon through the Lake Blue/Lake Cannon drainage ditch, which was identified as one of the main contributor of pollutants into Lake Cannon. The project was jointly funded by SWFWMD & Polk County and permitted through the FDEP. Construction was completed on January 1994. The alum injection stormwater treatment system is designed to treat the first flush of stormwater with aluminum sulfate (Alum). Test at that time show that the alum injection method is environmentally sound. Alum cleans stormwater by attacking certain pollutants and binding to them, forming an inactive sediment called "floc". The facility works by monitoring the flow of stormwater through the system. Alum is pumped or injected into the first flush of stormwater based on the rate of flow in the system. |
