Solid Waste Engineering
& Design Services
Practical solutions that maximize capacity, manage risk, and keep projects moving.
ARM Group provides integrated engineering and design services for active, expanding, and closed landfill facilities. Our multidisciplinary team considers permitting, constructability, operations, environmental compliance, and long-term performance from the start—helping owners make confident decisions and move projects from concept through construction.
Built for the realities of your facility
Every landfill project involves competing priorities: gain airspace, control costs, maintain operations, meet regulatory requirements, and protect environmental resources. ARM brings civil, geotechnical, environmental, hydrogeologic, structural, electrical, and automation expertise together to solve those challenges as one coordinated team.
We work with public and private owners on projects ranging from targeted system improvements to complete landfill expansions. Our designs are grounded in site conditions, informed by operational needs, and developed with construction in mind.

From Concept to Construction
ARM supports the full project lifecycle. We begin by understanding your operational goals, site constraints, permit requirements, schedule, and budget. From there, we develop practical alternatives, coordinate the required technical disciplines, and advance the preferred solution through permitting and final design.
During bidding and construction, our engineers and field professionals remain engaged to address questions, evaluate conditions, review submittals, and verify that the work meets the project documents and regulatory requirements. That continuity helps reduce surprises and keeps the design connected to what is actually built.
Why owners choose ARM for complex landfill projects
A clearer path through permitting
You gain a permitting strategy—not just a permit application. We identify regulatory needs early, coordinate the technical documentation, and work with agencies to help reduce approval risk and keep your project moving.
Designs that work in the field
Your design is developed around how the project will actually be built and operated. We consider earthwork, materials, phasing, site access, ongoing operations, and cost so you can make informed decisions and reduce construction surprises.
Continuity from planning through long-term performance
You have a team that can stay engaged from feasibility and design through permitting, bidding, construction, closure, and post-closure care. That continuity protects project knowledge, supports smoother handoffs, and keeps decisions aligned with your long-term goals.
One coordinated team for interconnected challenges
You can draw on civil, geotechnical, environmental, hydrogeologic, leachate, gas, stormwater, electrical, and operational expertise through one coordinated team—reducing gaps between disciplines and giving you solutions that work across the entire facility.
Put your next landfill project on solid ground
Whether you are planning an expansion, upgrading a critical system, evaluating remaining capacity, or preparing for closure, ARM can help you define the right path forward.
