About this file

These are permit drawings prepared by Weaver Consultants Group for the Pitkin County Solid Waste Center's proposed Leachate Impoundment Pond, issued for bidding purposes in April 2025. The comprehensive set of technical drawings includes nine detailed sheets covering site layout, sections, piping plans, and various infrastructure details for a new leachate impoundment pond project. The drawings provide technical specifications for a proposed pond with specific design elements including liner systems, extraction sumps, detection systems, run-on diversion berms, fencing, gates, and gravel access areas.

The project involves constructing a leachate management infrastructure at the Pitkin County Landfill, with key technical specifications including a geomembrane liner system using 60 mil HDPE liner, multiple layers of geotextile materials, compacted subgrade, drainage networks, and specialized piping and extraction systems. The site appears to be located in a topographically complex area with existing contours ranging approximately between 7,460 and 7,660 feet in elevation. The drawings indicate careful engineering considerations for environmental protection, including leachate detection mechanisms, proper liner termination details, and comprehensive site access and security features like chain-link fencing with specific gate designs.
