Presented by Jason D. Ross, P.E. of S&ME, Inc.
Webinar recorded June 25, 2019.

Dedicated to advancing the use of fabricated geomembranes through education, research, and technology transfer.

WHY?
Factory fabrication reduces field welding, reduces installation time and costs, allows modular construction and provides consistent seam and liner quality.

The FGI Pond Leakage Calculator
Geomembranes v. Compacted Clay Liners

Fresh water is a precious resource with demands rising daily and supply greatly fluctuating. Only two (2) percent of all water on Earth is fresh water with the other 98% being salt water.  This 2% of fresh water is comprised of: 87% ice, 12% groundwater, and 1% rivers and lakes.  Thus, only 13% of the available freshwater is readily accessible.  Therefore, it is imperative that we capture and hold these limited water resources for agriculture, domestic use, and industry and also protect valuable groundwater from surface or subsurface contamination.

The FGI’s Pond Leakage Calculator is a Microsoft EXCEL spreadsheet based on Darcy's Law of Seepage and provides a comparison between leakage rates from a canal, pond, or reservoir constructed with compacted fine-grained soils and a geomembrane liner system. The Leakage Calculator allows the user to input the size of the containment basin (including length, width, depth, side slope angle and freeboard), the anticipated level of hydraulic conductivity of the compacted soil or geomembrane liner, and the relative cost of water in dollars per acre-foot of water.

The Calculator then calculates the volume of the basin in gallons, a comparison of leakage rates between the compacted soil and geomembrane liner systems in gallons, and the cost of the leakage based on the cost of water per acre-foot to replace it. This Calculator is designed to help consultants, engineers, architects, and end users decide how to line their canals, ponds, reservoirs, and basins to capture and/or protect valuable fresh water.  The Calculator does not consider variances in construction quality and operational techniques on the long-term effectiveness of the chosen liner system. The FGI has additional research and publications to help with other aspects of successful water containment applications.

Types of Geomembranes
Four (4) popular types of geomembranes are available for pond liner systems.  These four (4) geomembranes in ALPHABETICAL order are: (1) EPDM, (2) reinforced polyethylene (RPE), (3) Polypropylene (PP), and (4) Polyvinyl Chloride (PVC). EPDM (Ethylene Propylene Diene Monomer) geomembranes are unreinforced and have been used for the construction of ponds of varying kinds. EPDM geomembranes are made from rubber and can be welded together with tape and primer. EPDM can be reinforced or unreinforced.  RPE geomembranes have a high tensile strength and puncture resistance because they are reinforced. RPE geomembranes also can be welded with heat.  PP geomembranes can be unreinforced or reinforced depending on the application. Reinforced PP geomembranes also have a high tensile strength and puncture resistance because they are reinforced. PVC geomembranes are also unreinforced and have been used successfully for decades in water canals, ponds, and reservoirs. PVC geomembranes can be welded with heat and/or solvents.

FGI Creates FREE Online PDH Credit Program

Earn PDH Credits Online

The FGI has created a program that will offer engineers one (1.0) Professional Development Hour (PDH) of credit for each FGI webinar that is viewed from the FGI Online Webinar Library. The FGI currently has thirteen (13) webinars in its online library and is offering an additional four (4) live webinars this year: CCR Regulations and Policy (August 6), Temporary Landfill Covers (September 10), Lightweight Aggregate (October 15), and Geomembrane Wrinkles (November 12). A PDH certificate will be issued to anyone who attends a live webinar or views a pre-recorded webinar in its entirety. Each live webinar will be added to the FGI's online library after the initial airing date.

FGI To Offer Coal Combustion Residuals Short Course

The Fabricated Geomembrane Institute is offering a one day short course on Coal Combustion Residuals (CCRs): Current Regulations and Solutions.  The short course will take place on Wednesday, November 6, 2019 at the Center City Building near the University of North Carolina Charlotte campus. Attendees will gain a broad knowledge of current and emerging CCR regulations, local experience managing CCRs, and the advantages of using geosynthetics to manage and dispose of CCRs.  Course attendees will earn seven (7.0) PDHs. Lunch and break refreshments will be provided. The short course is offered in collaboration with S&ME, Wood, University of North Carolina Charlotte (UNCC) and the University of Illinois at Urbana-Champaign. The short course will feature dynamic presentations from representatives of Consumers Energy, Duke Energy, American Electric Power, UNCC, The Ohio State University, Wind Defender, Wood, TRI, DemTech, Leister and S&ME.
