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 OFFERS FIRST EVER LIVE STREAMING SHORT COURSE

FGI OFFERS FIRST EVER LIVE STREAMING SHORT COURSE ADDRESSING GEOSYNTHETICS IN CIVIL ENGINEERING APPLICATIONS

The Fabricated Geomembrane Institute (FGI) presented a live-streamed short course at the University of Illinois at Urbana-Champaign (UIUC) on 3 August, 2018.  The short course was organized by the FGI and was streamed on-line by the Geosynthetic Materials Association (GMA). The short course was offered as a set of six continuous webinars, with a one-hour lunch break separating the three morning sessions and the three afternoon sessions.  The all-day short course drew 210 registrants, with over 100 attendees streaming at any one time.

The excellent and timely presentations focused on the challenges and environmental concerns with containment and engineering technologies and how geosynthetics and geomembranes can be used to mitigate the concerns and risks.  Andy Durham of Owens Corning served as the emcee for the short course; introducing each speaker, as well as moderating the live question and answer section at the end of each presentation. The beginning portion of the short course focused on geomembrane life and performance.  Dr. Kerry Rowe, of Queens University focused on service life of geomembranes, while GlenToepfer, of CQA Solutions provided insight into the latest advancements in geomembrane testing and certified quality assurance (CQA) procedures.  Finally, Dr.Kerry Rowe concluded the morning sessions with an informative presentation on the effects of wrinkles on geomembrane performance.  

The second half of the presentations focused on various applications of geosynthetics in civil engineering applications.  For example, Sam Allen, of TRI Environmental reviewed the best practices for zero leak containment.  Gary Zych, of American Electric Power in Columbus, Ohio gave an informative presentation on effective disposal techniques for Coal Combustion Residuals using PVC geomembranes.  Finally, Dr. Timothy Stark, of the UIUC wrapped up the live-streamed event with a presentation detailing elevated temperatures in containment applications.  

Many attendee questions, comments, and experiences made the course a great success. The topics and speakers from the successful short course are shown below:

FGI Accomplishments and Current Activities – A Midterm Review

This article highlights a few of the accomplishments of the current Officers and Board of Directors, as well as the projects in which the FGI is currently engaged.

It has been over a year since the Fabricated Geomembrane Institute (FGI) inducted new Officers and a new Board of Directors, which occurred in March of 2017 at the ASCE Geo-Frontiers Conference in Orlando, Florida.  Officers and Board of Directors currently serving are: 

President – Patrick Elliott (Raven Industries, Parker, Colorado), Vice President – Laura Storey (Consumers Energy, Saginaw, Michigan), Treasurer – Ed Silva (Engineered Polymer Technologies, Hillside, New Jersey), Secretary – Andy Durham (Owens Corning, Granville, Ohio), Dale Kemnitz (Leak Location Services), Ray Peebles (Cooley Group), Bill Shehane (Seaman Corporation), and Duff Simbeck (Simbeck & Associates).  A few accomplishments of the current Officers and Board of Directors are highlighted below:
