Practical Stormwater Treatment From A-Z:
A Special Training Opportunity for Stormwater Managers and Consultants

Monday, August 2, 2010
8:00 a.m. – 4:00 p.m.
0.5 Continuing Education Unit

Course Description
Selecting the right Best Management Practices (BMPs) is crucial for achieving water-quality goals. Understanding the array of choices and the conditions in which different BMPs are most effective is equally critical. This comprehensive workshop guides program managers and engineers through the criteria necessary to make appropriate selections. It begins with a discussion on the types of pollutants and their sources and moves onto an overview of the pollutant removal unit processes.

Discussion will address impaired waters and TMDLs, and the difference between new development BMP design and retrofitting existing development for TMDL compliance. A detailed description of 33 BMPs will be given—from ponds, alum injection systems, and constructed wetlands, to various types of media filters, inlet devices, sand filters, hydrodynamic devices, and more. A section on selection criteria provides participants with a list of factors for making the best choices, including pollutant removal effectiveness, types of pollutants, available space, groundwater level, soil type, and maintenance costs.

The workshop will also include discussions of first flush, monitoring of BMPs, BMP databases, and the role of low-impact development practices and stormwater reuse. Various models of pollutant loading calculations for TMDL compliance and pollutant removal calculations for BMPs and treatment trains will be demonstrated along with a method for designing pre- versus post-pollutant loadings. An in-depth look at BMP inspections and maintenance will also be presented along with a method to track sediment removals from street sweeping and maintenance activities to achieve reductions in TMDL allocations.

Stormwater Pollution Modeling for LID, TMDL, and Retrofitting Analyses— An Overview of WinSLAMM

Monday, August 2, 2010
8:30 a.m. – 4:30 p.m.
0.5 Continuing Education Unit

**This course requires all attendees to have a laptop computer with them for use during the course. If you plan on attending with someone from your organization, you may also share a computer.

Attendees with their own laptop may use a temporary license of the model during the course.  WinSLAMM can be run on a PC with Windows XP, Vista, or Windows 7, and will need a CD drive and/or a USB port to load the program. You will need administrative privileges for the computer if the program is not pre-loaded.

Course Description
This hands-on computer-based course will demonstrate how to use WinSLAMM to utilize source area stormwater controls to maintain or create a hydrologically functional landscape that mimics natural watersheds’ hydrologic functions (volume, frequency, recharge, and discharge). By integrating source area controls into site design, you can approach the pre-development sites ability to retain water and pollutants. 

You will learn to:

• Quantify pollutant sources in complex urban watersheds
• Predict the performance and impact of many interacting development and control options
• Calculate pollutant loads and runoff volumes from various structural and non-structural management scenarios
• Estimate and compare the costs of stormwater control practices.

About WinSLAMM
WinSLAMM is a Windows-based, continuous simulation computer program, that helps water resources professionals make effective decisions by modeling the stormwater impacts of new or existing developments and evaluating the benefits of various control measures. The WinSLAMM model has been used for over 15 years to calculate urban stormwater runoff volume, pollution loads, and assess a wide range of management measures. The model enables accurate planning-level and design-level analyses. Wisconsin’s Department of Natural Resources has adopted the model for regulatory compliance purposes. The WinSLAMM batch processor provides data for decision makers to select the most cost-effective alternative stormwater control practices. WinSLAMM is typically used in continuous simulations of at least one year of local rain events to examine these issues over a wide range of actual site conditions.

The 1-day course will cover:

• Modeling terminology and preparing to model
• WinSLAMM theory and practice
• WinSLAMM model features and navigation
• Base file setup
• Grass swale & filter strip modeling/design
• Biofilter modeling/design
• Analyzing an example LID subdivision development for stormwater volume & TSS loads

**This course requires all attendees to have a laptop computer with them for use during the course. If you plan on attending with someone from your organization, you may also share a computer.
