Stormwater Infiltration Basin Design - Design Consideration and Example Projects

*Open only to Central Ohio Section Members
*Seating is limited to the first 25 people
*Bring your own lunch

Purpose and Background
As the National Pollutant Discharge Elimination System (NPDES), state and local water quality management regulations increasingly limit impacts to receiving water, stormwater management and the use of Best Management Practices (BMPs) have become a primary design consideration for most civil engineering projects in the U.S. Many states provide stormwater BMP design guidance documents to aid engineers with the selection and proper design of many types of structural BMPs. However, with the variability of soils, topography and other design constraints that occur between sites, it is often difficult to determine which BMP will be the most appropriate and cost effective solution. This webinar will review guidance documents and use example projects to demonstrate how to determine when a site is appropriate for the utilization of dry bottom infiltration basins that rely on in-situ soils for stormwater quantity and quality treatment.

Webinar Outline

• Determine your regulatory requirements
• Design criteria
• Soils and seasonal high water table evaluation
• Topography and other site constraints
• Design volume determination
• Bypassing excess volumes or over size the basin
• Advantages and disadvantages
• Maintenance considerations

Learning Outcomes

• Identify sites that are well suited for the use of infiltration BMPs that rely on appropriate in-situ soils
• Understand primary design considerations
• Determine treatment volume and account for runoff volumes from storms that exceed the design storm
• Learn limitations of the use of infiltration basins through design examples and real world challenges

Webinar Benefits

• Learn how to find sources for design guidance
• Improve understanding of infiltration basin design
• Gain understanding of how soils, water table and other site constraints govern design
• Become familiar with treatment volume determination and bypass methods
• Solidify concepts through example projects

Intended Audience
This webinar will benefit stormwater and civil-site engineers, Engineers in Training (EITs), environmental planners and scientists, designers and technicians who work in both the private and public sector by providing a better understanding of the use and limitations of infiltration basins for the management of stormwater quantity and quality from existing and proposed built upon area.

The Central Ohio Section of ASCE sponsors free continuing education webinars as a service to our members. These webinars are produced by ASCE and normally cost $250 or $300 for ASCE members. However, the Central Ohio Section is paying the registration fee and inviting any interested section members to attend for free. Just RSVP by the deadline. Seating is limited, so do not delay.

You can see the complete list of webinars available from ASCE National on their website. If you see one you like, let us know. If you and your company would like to host one, let us know that too. If you open it up to any interested Central Ohio ASCE section members to come, we will pay the registration fee.
