Scope of the Project

• Soil Lost 2500 cubic yards
• ERE Maps, Tape Measure
• Estimated Dimensions and Volume
• Primary Sludge 25,000,000 lbs
• 1 cubic yard soil weighs 2000 lbs
• 1 lb soil creates 5 lbs primary sludge

9
Scope of the Project

• Yearly Sludge Production 1,250,000 lbs
• 25,000,000 lbs total
• 50 of erosion occurred in past 10 years
• 10 of WWTP Sludge in 2005
• 2005 WWTP Sludge 13,540,022 lbs

10
Recommendations

• Armor Stormwater Channels
• Groundcover
• Global Fill
• Rock
• Protecting Inlets and Outlets
• Procedural Changes

Cost Estimate

• Total Cost 170,000 - 300,000
• High-Priority Areas (170,000 - 200,000)
• Entire Area (250,000 - 300,000)
• Soil makes up 95 of this cost
• Cost varies according to material use

12
Benefits of Erosion Control

• Decreased Primary Sludge Generation
• Improved WWTP Efficiency
• Increased Capacity to Recycle Other Sludge
• Decreased Storage Needs
• Improved Stability of Pipe Rack Foundations
• SWP3 Compliance
