Advanced Turbidity Treatment Systems

Advanced Treatment Systems or ATS has proven effective for turbidity control for several years. While all agencies are not in universal agreement on the elements of ATS or the regulations for the use of ATS this webinar introduces the required elements for successful monitoring and treatment of construction site runoff for both turbidity and pH control. ATS can involve chemical flocculation, electrocoagulation, filtration and gravity settling. This seminar will follow and build upon the flocculation presentations of Dr. Richard McLaughlin Ph.D. to incorporate the use of automated systems designed to monitor and treat Stormwater using automated chemical dosing and filtration systems to consistently treat construction site discharges to acceptable levels.

Basic Hydrology - Part 1

Knowledge of hydrology is essential for individuals interested in water quality and those involved with land use management activities including erosion and sediment control, designing and reviewing stormwater management plans, as well as local and state regulators and decision makers. This course will describe and discuss the factors that influence stormwater runoff and demonstrate the methodology and procedures to quantify runoff volumes. Precipitation, drainage areas, hydrologic soil groups, land use cover and hydrologic conditions will be explained, through a design example, to convert rainfall to runoff by using USDA-NRCS TR55 hydrologic analyses. Watershed runoff volumes will be calculated.

Basic Hydrology - Part 2

This course will take participants through the evaluation and determination of the parameters for the time of concentration for a watershed and its application in determining the peak rate of runoff for different storm frequencies in the watershed. The USDA-NRCS unit hydrograph use will be explained and its use to calculate the peak discharge will be demonstrated through a design example. Comparison of pre-developed and post-developed discharges will be made for estimating stormwater detention basin sizing.

Building Green: Atlanta's Green Infrastructure Approach

The City of Atlanta has embraced the use of green infrastructure as a means of combined sewer capacity relief, ecosystem restoration, economic stimulus, and water quality control. In February of 2013, Atlanta adopted one of the most far-reaching stormwater management ordinances in the country.Ê The ordinance helped lay the groundwork for a robust green infrastructure program, both for private development as well as capital improvement projects undertaken by the City.Ê To date, the City has permitted over 2,000 construction projects that utilize green infrastructure to reduce the volume of polluted runoff. ÊIn addition, the City is currently installing the largest permeable paver roadway project in North America - six miles - to help alleviate flooding in neighborhoods served by the City’s combined sewer infrastructure.

Changing the Development Paradigm to Embrace LID - Part 2

The Basis of Low Impact Development: In this webinar attendees will learn about the most important aspect of Low Impact Development (LID), Environmental Site Design (ESD). ESD is the cornerstone of the LID approach by evaluating the natural resources on the site and placing the development on the land which is most suitable for it. The natural environment provides many positive benefits especially related to the rainfall runoff relationship. These many benefits will be discussed and it will be demonstrated how the application of ESD for residential development can preserve many of these benefits, while at the same time mimic the natural hydrologic relationship for small, frequent rainfall events. The common hydrologic goals associated with LID will also be discussed and it will be shown how ESD can help a designer meet these goals. In addition to the hydrologic benefits of ESD, the preservation of woodlands and meadows also provide other environmental benefits such as the sequestering of carbon.

Changing the Development Paradigm to Embrace LID - Part One

The Problem with Conventional Development & Stormwater Management: This webinar will investigate and demonstrate the many impacts, associated with our current approach of prescriptive land use policies and stormwater management that have led to adverse impacts to our natural environment, particularly aquatic systems due to “the law of unintended consequences” of these policies. The webinar will also introduce attendees to the concept of Low Impact Development (LID) which is a paradigm shift in how development and stormwater is done to minimize the impacts of development on the natural environment. A history of LID will be provided as well as a discussion of how LID works and why it is a much better approach for land development projects.

Construction Site Erosion and Sediment Control: Best Practices and Low Impact Solutions

Often construction-phase and post-construction stormwater management are separate worlds (different permits, different plans, different practices, etc.); however, in terms of hydrology, water quality and the ultimate success or failure of post-construction practices, they are closely related. This webinar will briefly review stormwater regulations for construction and post-construction and will explain how hydrology is a unifying theme. The webinar will include state-of-the-practice details for common LID and GI practices and will focus on details that are important to pay attention to during construction for successful stormwater quality management for the long term.

Controlling Turbidity: Getting Flocculation to Work on Your Site

While the US EPA has withdrawn its proposed turbidity limit on construction site runoff, there are still many states have or are proposing their own enforcement levels. Construction site owners and managers are also looking for ways to avoid public outcry and potential lawsuits over muddy water leaving their site. In most cases, typical and even more advanced erosion and sediment control practices will not prevent discharges that look like chocolate milk. This two-part seminar will explore the principles behind chemical treatments to rapidly settle suspended solids and reduce turbidity in runoff from construction sites. In the second part, he will then go over a variety of methods to apply those principles to greatly reduce turbidity. After conducting research on this subject for over 10 years in both laboratory and active construction site setting, McLaughlin has a lot of data to back up his recommendations! He will wrap up with a discussion of suggested chain of command options to avoid failures.

Erosion Control in Arid Climates

When constructing in arid environments erosion and sediment control is often overlooked. Emphasis is on dust control and wind borne erosion with erosion from water and runoff left as an after-thought all too often. In arid environments when a rain storm occurs contractors are left scrambling while being reactive and developers are left exposed to risk and unaccounted for costs. Learn how to successfully stabilize soils in areas with less than 10 inches of annual rainfall (on average), as well as how to establish vegetation in such extreme climatic conditions in a proactive manner.
