Historically limited by scalability and reliability issues, chitosan-based biocoagulants are now a robust solution, made possible through advanced formulations and rigorous U.S. based manufacturing standards. With the highest rating under the EPA's Safer Choice certification, chitosan presents a non-toxic, highly effective option that consistently performs in diverse stormwater systems, providing a green pathway to reduce pollutants and protect aquatic ecosystems. This interactive presentation will dive deep into a case study involving a meat packaging facility in Georgia where stormwater is also being treated int he same system. Chitosan-based biocoagulants replaced aluminum and caustic chemicals in their onsite activated sludge wastewater treatment facility.

Detention is an extremely important factor in flood management, it is also expensive, yet we use flow control technology that is hundreds of years old to size and manage these systems. The reason? Designers are not aware that there are viable alternatives that are easy to use and very effective at optimizing detention systems. This presentation will highlight alternative flow controls that employ vortex flow control system and case study projects that have gained significant benefits from the use of these advanced passive controls, including significant cost reductions.

Join us to learn about flaws with existing detention pond design methodology and how the concept of utilizing filtration with ponds can improve pond function. This new concept can provide higher treatment rate of more of the annual rainfall and do so with a smaller pond. Sound too good to be true? Its not and we have testing to prove it!

Recent wildfires in Southern California have necessitated a rapid post-fire response to address hazards related to debris flows, flooding, and erosion. This webinar will provide an overview of post-fire hazards and mitigation measures that can be implemented to reduce risk in a post-fire setting.

Traditional stormwater inspections are often time-consuming and inefficient, leading to compliance risks, costly delays, and regulatory penalties. This session will explore how AI and automation can streamline compliance workflows, reducing errors and improving efficiency. Stormwater and erosion control expert Jessica Acosta will break down the challenges of manual inspections and introduce AI-driven solutions designed to enhance accuracy and simplify compliance. Attendees will gain actionable insights on integrating digital tools into their existing workflows, ensuring smoother operations and regulatory adherence.

Since being awarded the IECA educational award in 2022, the On-Country Soil Erosion and Sediment Control training has continued to deliver unique and geographically experiences across Queensland. The training has offered a safe, inclusive, and experiential learning base for its attendees that not only expanded upon the best practice principals and techniques from IECA but exposes all participants to landscape and cultural insights only available when leaving the classroom and walking Country. Shared and integrated knowledge of air, water, soil, vegetation, and people. The content delivery on Country takes an empowering shift away from a teacher to pupil model and embraced a collaborative and adaptive approach. This presentation will talk through our recent presentations, learnings and the next steps for the program.

Water quality and detention are becoming increasingly necessary to ensure the health and safety of our communities. Texas has beautiful and unique natural environments which include endemic and endangered species, parks, lakes and spring fed rivers that are used for recreation. With Texas growing at a substantial rate, it is imperative that we prevent pollution for our community and environment. The City of San Marcos developed a routine inspection program for permanent stormwater detention and water quality controls. If these controls are operating as designed, they will improve water quality in our waterbodies and help decrease flash flooding.

Flocculants are powerful tools that have been used for decades to control erosion, stabilize soil, and remove harmful contaminants from water. Flocculant treatments can meet very low discharge limits, allowing sites to stay in compliance, meet regulations and improve stormwater quality and clarity. Anionic polyacrylamide is the most widely accepted and commonly used flocculant due to being safe for aquatic life, and highly effective, and extremely versatile. This webinar will explore the benefits of aPAM technologies, approval and current use in New Zealand, as well as future usage in the region.

On the Takitimu North Link Project there is a complex set of stream diversion and culvert installation works being undertaken which have provided numerous erosion and sediment control challenges. A new stream channel is being diverted adjacent to an existing closed out landfill. However, it was discovered that there was a large volume of rubbish outside the footprint of the leachate line which turned a straight forward stream diversion into a complex contaminated land remediation exercise whilst working beneath the water table and within large volumes of leachate runoff.

The objective of this class is to review and gain an understanding of the RUSLE calculation (Revised Universal Soil Loss Equation, and its impact on sediment and erosion control in the construction industry.

Steve Polk and Ted Hartsig team for this Two Session program that will inform attendees about existing knowledge gaps that are plaguing designers and contractors of post-construction stormwater BMPs/SCMs. During professional careers spanning more than 40 years, Polk and Hartsig have seen far too many projects badly because key participants in the stormwater compliance industry still doesn't "know what they don't know," and in many cases "don't have the time" to investigate. During this program, Steve and Ted will inform you about some of the most frequent problems that drive teams to an unfulfilling project results.

Join Aaron Harper and Donald Pearson as they share four decades of experience highlighting the significance of groundcover and vegetation in linear construction, particularly from the Piedmont to the Coast of North Carolina.

Join our webinar on "Regenerative Ecological Fitness in Erosion Control" to explore how integrating Indigenous wisdom and sustainable practices can transform erosion control into a cost-saving and ecologically beneficial strategy. Learn from Townsville's success in creating its own SESC products and services, showcasing practical applications and new business opportunities that enhance ecosystem resilience and reduce costs.

Since 2001, GTC has used “shredded” wood material generated from tree clearing activities to immediately stabilize transmission line rights of way. The shredded wood material degrades in a mosaic pattern which extends protection from erosion and sedimentation as vegetation re-establishes.

Increased rainfall intensity with climate change is being incorporated into design rainfalls and runoff guidelines which can be used for erosion and sediment management on construction sites. Erosion and sediment controls are beneficial for construction sites impacted by increases in high intensity rainfall events to meet legislative requirements and reduce the burden on sediment basins.
