Modern landfills are designed to be much more efficient and provide more air space for longevity even as we endeavor to recycle and reuse waste in new ways.


Dr. Ali Khatami, PE, is SCS Engineers’ National Expert for Landfill Design. Over his 40-year career, he has developed countless innovative engineering solutions to improve landfill design and function. Dr. Khatami generously shares his wealth of knowledge and expertise with clients and colleagues. He prepared a series of in-depth videos to explore various landfill design components. In this first blog, we introduce Dr. Khatami’s videos that cover modern landfill design and best design and construction practices. These modern approaches provide greater efficiencies and financial savings, with elegant and often simple solutions to issues that challenge landfills.

Modern Landfill Design

This webinar covers the advantages of modern landfill engineering and system design. Today’s modern landfills offset inflation and labor costs through transformative reduction, recycling, and reuse programs while turning methane into renewable energy. Advanced remote monitoring and control technology and data capture provide many efficiencies and insight to landfill operators and owners running increasingly larger collections of plants and facilities. This trend necessitates more landfill design sophistication and master planning to recoup the growing capital investment. In this webinar, Dr. Khatami discusses modern landfill design, focusing on optimizing site layout and maximizing air space – a landfill’s golden egg. [Run time 1:10:03]

Temporary Caps over Landfill Slopes

Dr. Khatami explores the benefits of placing temporary caps over landfill slopes and provides best practices. Advantages include delaying construction of the final cover, allowing additional settlement before final cover (thus increasing capacity), temporarily eliminating percolation of rainwater into waste (thus reducing leachate), improving gas collection, improving odor problems, and improving aesthetics.

Surface Water Swales and Downchutes in Landfill Final Covers

Dr. Khatami explores a surface water management system for landfill final covers that SCS Engineers has used for many facilities. The system is very effective and efficient and is simple to construct. It easily channels water from the slopes to the perimeter ditches without causing erosion or slope problems. Dr. Khatami walks through the components of the system and takes us through the construction step-by-step. [Run time 40:50]
