Retention ponds are used in a number of situations to remove pollutants prior to discharge into receiving streams. Small ponds are often seen near parking lots, gas stations, or neighborhoods where the ponds are used to treat for oil sheen, fertilizer run-off, and other pollutants. Larger ponds are often found at the end of wastewater treatment systems and are vital for "polishing" the effluent by removing residual TSS while removing small quantities of BOD, ammonia, phosphate, or other criteria pollutants.

While the ponds are effective and easily managed for much of the year, algae related TSS can become a treatment issue during summer months. The algae bloom is related to long days, warm temperatures and the residual nutrients (N & P) in the water. This algae related TSS increase can create problems with effluent permits, disinfection with UV or chlorine, and odors/appearance issues.
