Water Infrastructure

Comprehensive Solutions for Resilient Water Systems

We are committed to delivering innovative and sustainable solutions for water infrastructure projects. Our multidisciplinary team works across all aspects of water infrastructure development, offering expertise that integrates engineering, environmental science, and regulatory compliance. From initial planning and feasibility studies to detailed design and construction oversight, we ensure that projects are optimized for performance, cost-efficiency, and environmental stewardship.

By addressing challenges such as aging infrastructure, climate change impacts, and stringent regulatory requirements, we help municipalities, utilities, and private clients create resilient systems that support community needs and protect valuable water resources for the future.

Planning and Management

Effective water infrastructure starts with thoughtful planning and management. NTH develops comprehensive strategies to ensure that water systems are efficient, sustainable, and adaptable to future challenges.

Stormwater and Watershed Management Plans: Tailored solutions to manage water flow, reduce flooding risks, and protect natural resources within urban and rural environments.
Hydrogeologic Studies: Detailed evaluations of groundwater and geological conditions to support sustainable water sourcing and infrastructure planning.
Infrastructure Assessments: Condition assessments and asset management strategies to help clients prioritize investments and extend the life of their water systems.

Environmental Compliance and Permitting

Navigating complex regulatory landscapes is critical to water infrastructure projects. NTH provides expert support to ensure that all projects meet local, state, and federal requirements.

NPDES Permitting: Assistance in obtaining and maintaining National Pollutant Discharge Elimination System permits for water discharges.
