• Expect $100,000 + capital and additional O&M
Cost
• Choose vendors who will provide training and support
Vendor Support
• Dogs and new tricksPersonnel

Evidence from 3 case studies supports that GPS can improve landfill compaction
Evidence from 3 case studies supports that GPS can improve landfill compaction
Compaction improvements can be significant
Even small compaction improvements bring large $ gains
33
Manage the GPS SystemsManage the GPS Systems
Choose a responsive vendor
Train operators
Update hardware and software as necessary
Add repeaters as needed
