GSI to host webinar on pond liners

January 20th, 2020 / By: / Events

The Geosynthetic Institute (GSI) will sponsor a webinar, “Pond Liner Design and Performance,” on Feb. 19, from 11:30 a.m. to 1 p.m. EST. Geosynthetic Materials Association (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. In addition to hazardous types, other liquids being contained are potable water, architectural ponds, industrial water, sewage sludge, dredged sediments, agriculture wastes, slurried coal combustion residuals, 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 discrete design stages. These design stages contain both numeric examples and past failures 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 which 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.

The webinar is intended for public and private owners of the following types of liquid impoundment facilities:

  • potable water
  • architectural ponds
  • shutdown water
  • industrial waters
  • process wastewaters
  • sewage sludge
  • industrial sludge
  • agricultural wastes
  • slurried CCRs
  • hazardous liquids

As such, regulators and agency personnel, consultants and designers, soil and geosynthetic testing organizations, contractors and installers, academic and research groups, and lay people who are desiring technical related information on this important topic are welcomed.

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