Laramie Landfill Design & Development

Laramie, Wyoming

The Laramie Landfill supports an average annual volume of 36,400 tons of solid waste. Prior to the start of the project, the facility lacked basic infrastructure, including electricity, water, and sewer. To prepare for future cost-effective and environmentally-friendly solid waste management practices, the City of Laramie (City) requested design upgrades to the existing system and infrastructure.

Trihydro was selected to design, permit, and provide construction administration and management services for the lateral expansion of the landfill, including the design of an engineered containment system (ECS). The installed ECS provides an impermeable barrier between the waste and soils, which allows for the collection and handling of waste liquids and prevents subsurface soils and groundwater contamination.  

The project also included the construction of a new main entrance to the facility, as well as a 24,000 square foot baler building, scale house, computerized hydraulic truck scale, and Z-Wall waste diversion area. The new entrance allows the City to more efficiently handle and track incoming waste, separate recyclable materials, limit litter, and provide quicker and safer waste disposal for customers.  

The success of this project can be attributed to Trihydro’s solid waste and construction management experience and the fostering of an overall “team” mentality held by all subconsultants, contractors, and subcontractors involved with the project. The mentality lead by Trihydro personnel kept all parties working together towards the same goal: providing the client with a quality product. In the end, the City and community are benefiting from a state-of-the-art solid waste disposal facility which is designed to protect the health and safety of customers and the environment. The project was completed under budget in February 2014.

The existing landfill had no permanent utility infrastructure, requiring construction of new asphalt and gravel access roads, water supply lines to an offsite transmission main more than 1,000 feet away, connection to electrical power supply over 1,400 feet from the site, and a new septic plumbing system.
