Landfill Design & Engineering Services

Comprehensive Expertise for Landfill Development

The siting, design, and construction of sanitary and hazardous waste landfills demand a deep understanding of complex regulatory requirements and technical challenges. We bring decades of experience to landfill projects, offering tailored solutions that ensure compliance, efficiency, and community acceptance.

Since 1972, we have supported major landfill companies, municipalities, and independent operators, with landfill siting, design, construction, and post-closure monitoring. Whether developing new facilities or managing vertical and horizontal expansions, we provide the expertise needed to deliver high-quality, regulatory-compliant landfills.

Siting and Design

NTH’s experienced team excels at navigating the complexities of landfill siting and design. We optimize the use of available land and materials while ensuring full compliance with federal, state, and local regulations. Our services include:

• Site selection and evaluation
• Cell design and optimization
• Leachate and gas control system design
• Closure and post-closure planning

Our goal is to create facilities that maximize operational efficiency while minimizing environmental impact and meeting community expectations.

Construction Monitoring

Construction monitoring is essential to the successful development of landfill facilities. NTH provides rigorous oversight to ensure that all components are built to design specifications and regulatory standards. Our expertise includes:

• Monitoring clay liner compaction
• Overseeing flexible membrane liner (FML) installation, including HDPE, LDPE, and PVC systems
• Conducting field and laboratory testing for quality control

Our team enforces strict QA/QC protocols and prepares comprehensive documentation for regulatory compliance. NTH has also developed state-approved quality assurance programs for synthetic liner projects, ensuring the integrity and performance of these critical components.
