To prepare for future solid waste management practices, the City of Laramie requested design upgrades to its existing system and infrastructure. Trihydro designed, permitted, and provided construction oversight for the landfill's expansion, which included an engineered containment system, a new main entrance, a baler building, a scale house, a truck scale, and a Z-Wall waste diversion area.

The Laramie Landfill supports an average annual volume of 36,400 tons of solid waste. Before 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 constructing 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 project's success can be attributed to Trihydro’s solid waste and construction management experience and ability to foster a “one-team” mentality held by all involved subconsultants, contractors, and subcontractors. The mentality demonstrated by Trihydro personnel kept parties working together toward 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 designed to protect the health and safety of customers and the environment.
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.
