GSI to host webinar on pond liners, GMA members get discounted rates

The Geosynthetic Institute (GSI) will sponsor a webinar “Pond Liner Design and Performance,” on Jan. 10, 2019, from 11:30 a.m. to 1 p.m. EDT. GMA member companies and their employees receive discounted rates on all GSI webinar and short course registrations.

The first ponds lined with geomembranes were installed in the 1930s. That said, the application has grown enormously to the present. For example, of the many types of contained liquids, the hazardous types alone represent 206,000 as estimated by the U.S. EPA. Other liquids being contained are potable water, architectural ponds, industrial water, sewage sludge, dredged sediments, agriculture wastes, slurried coal combustion residuals (CCR), etc. This webinar focuses on design of such facilities (which are fully illustrated) and their performance (which is shown to be “dicey.”)

The webinar proceeds in discrete design stages whereby the output of one stage feeds directly into the next. In this regard, an overview is first presented followed by eight design stages. These design stages contain both numeric examples and past failures so as to focus upon specific aspects of the entire process. Indeed, proper pond liner design leads directly to fully acceptable results provided that proper construction quality control and assurance are subsequently implemented.

Participants will understand that pond liner design is not a simplistic process of selecting a geomembrane, getting a warranty, and subsequent installation in a cavalier manner. Conversely, it is a prescribed methodology that will be fully explained and illustrated. Many of the design aspects utilize geotechnical, hydraulic and polymer knowledge, which are illustrated by numeric examples. The ultimate objective being a safe and secure system properly functioning for the intended lifetime that is envisioned.

This webinar will be beneficial to public and private owners of liquid impoundment facilities, including potable water reservoirs, architectural ponds, shutdown water, industrial water ponds, process waste water, sewage, industrial sludge, agricultural waste, slurried CCR and hazardous liquids; regulators and agency personnel; consultants and designers; soil and geosynthetic testing organization employees; contractors and installers; academic and research groups; and laypeople who are desiring technical related information on this important topic.

The webinar’s instructor, Dr. Robert M. Koerner, is professor emeritus of civil engineering at Drexel University, and founder and director emeritus of the Geosynthetic Institute.

Webinars cost $200.00 for GSI and Geosynthetic Materials Association (GMA) members, and $250.00 for nonmembers. Successful completion of a multiple-choice test after the webinar carries 1.5 professional development hours (PDH).
