Landfill Design Considerations in the Age of Sustainable Development

APRIL 6 – 7

1st Half of Course (Koerner)

This training course is to advise both design engineers and regulators as to the engineering design challenges related to capacity optimization at today’s landfills. It is harder than ever to site new green field disposal facilities. As a result, many existing landfill operators seek engineering solutions to help maximize the disposal capacity of their existing landfills.

  1. Introduction and overview
  2. Liner system
  3. Filtration and drainage
  4. Instability
    1. Liner
    2. Waste
    3. Cover
  5. Lateral and vertical expansions
  6. Landfill performance
  7. Concerns and functional longevity

In light of the new emphasis on carbon footprint, this course revisits the sustainable landfill concept. While the concept is not new, it can be viewed in terms of today’s focus on sustainability and how it relates to reduction of emissions and reducing environmental impact. This course takes a look at how landfills can achieve the goals of being environmentally friendly and cost-effective at the same time. This course will show how geosynthetics can improve landfill performance, and how they are the key to eventually fulfilling the promise of a sustainable landfill.

2nd Half of Course (Gilson)

Intended for owners, design engineers and construction quality assurance personnel, this portion of the class will focus on Electrical Leak Location (ELL) as a tool for ensuring containment facility performance.  The class will cover every aspect of ELL surveys, including how the methods work, ASTM standard practices, factors in leak detection sensitivity, how to prepare a site for an ELL survey, and method specification.


1. Significance of Electrical Leak Location
Hole Statistics
3. Available ELL methods
          a. Exposed Geomembrane Methods
          b. Covered Geomembrane Methods
4. Performance and Material Specification
5.  ELL specifications
6.  Artificial leaks, actual leaks and blind leaks
7. Case Histories
