Wet Pond Treatment Processes
• Settling
• Plant Uptake and Adsorption
• Infiltration
• Evaporation

Wet Ponds - Criteria
• Provide Quantity and Quality Control(not volume control)
• Drainage Area: Minimum of 10 Acres (>25 Acres Preferred)
• Treat Water Quality Volume• Retrofit Opportunities• Maintenance

Wet Pond – Hydraulic Design
• Design Pond Using Acceptable Methodology– NRCS…TR55…TR20– Penn State Runoff Model (PSRM)– Modified Rational Method– Other
• Hydrograph Routing Is Necessary

Wet Pond – Area Ratio
Area Ratio = Drainage Area
Pond Area
Should Be Less Than 100
For Maximum Efficiency

Conventional Detention Basins
• Designed For Flood Control & Channel Protection
large storm events (50 year…100 year)
• Do Not Control: runoff volumewater quality
• Do Not Provideaestheticswildlife habitat

Retrofitting Detention Basins - Benefits
• Pollutant Removal
• Water Quality Improvement
• Wildlife Habitat Creation
• Aesthetic Improvement
• Reduced Maintenance
