Water shapes communities in profound ways. It sustains life, drives growth, and supports healthy ecosystems. It also floods neighborhoods, erodes infrastructure, and threatens the natural systems that make communities livable. Ardurra's water resources professionals work at that intersection — protecting people and property while restoring the natural systems that support them.

We provide comprehensive watershed services across the full project lifecycle, from initial planning and modeling through final construction and monitoring. Our teams combine rigorous engineering with sound ecological thinking, delivering solutions that reduce risk, improve water quality, and create lasting value for the communities and environments we serve.

Our Approach

Water resources challenges rarely arrive in isolation. Flooding, stormwater quality, aging drainage infrastructure, regulatory mandates, and degraded natural systems often overlap — and solving one without considering the others creates new problems downstream. Ardurra takes a whole-system view, integrating hydrology, hydraulics, ecology, and regulatory strategy into solutions that are technically defensible, cost-effective, and built to last.

Our water resources practice draws on deep expertise across stormwater master planning, flood control, watershed management, drainage design, green infrastructure, stream and channel restoration, NPDES compliance, TMDLs, and FEMA coordination. We work with municipalities, counties, state agencies, and regional authorities — bringing the same rigorous analysis and responsive partnership to a neighborhood drainage study as we bring to a regional flood control program.

Ardurra serves municipalities, county and regional water districts, stormwater utilities, private developers, airports, and agricultural clients. Our ability to scale, from local on-call support to large multi-year master plans and construction programs, means clients get the right level of engagement for their project, not a one-size-fits-all approach.

Water systems do not get a day off. They protect public health, support growth, meet evolving regulations, and perform reliably for the people who depend on them — day in, day out. Ardurra partners with utilities, municipalities, and public agencies to plan, design, and improve water infrastructure with the urgency and care these systems deserve.
Our teams bring an entrepreneurial spirit, local insight, and national technical depth to complex water challenges. From source protection and treatment to reuse, conveyance, wastewater, and resource recovery, Ardurra helps clients build solutions that protect critical resources and support resilient communities for generations to come.

Our Approach

Today’s water challenges are layered. Aging infrastructure, climate pressures, population growth, emerging contaminants, tightening regulations, and funding constraints all compete for attention simultaneously. Ardurra's low-bureaucracy, client-driven model lets our teams work directly alongside yours — evaluating options quickly, cutting through 
complexity, and moving from strategy to implementation without losing momentum.

Our water and wastewater practice covers the full range: planning and modeling, funding strategy, design, construction management, design-build, and operations-focused solutions. We look at the full system, not just the immediate project need — helping clients modernize assets, improve performance, manage risk, and make decisions that align with long-term community priorities.

Whether modernizing treatment systems, advancing reuse, improving conveyance, addressing new contaminants, or planning for long-term resilience, Ardurra delivers technically robust, practical-to-build, and efficient-to-operate solutions. We help clients evaluate emerging technologies and delivery methods to improve performance, accelerate implementation, and create lasting value — from initial planning through design, construction, and operations support.

Other Ways We Make an Impact

Water infrastructure decisions have long consequences. Ardurra brings specialized depth across the disciplines that help clients plan smarter, operate better, and stay ahead of what's coming.

Hydrologic & Hydraulic Modeling

Hydrologic and Hydraulic (H&H) modeling is the cornerstone of modern, resilient water resource management, offering a proactive, data-driven approach to understanding and managing water behavior. As urban areas expand and environmental regulations tighten, precise hydraulic modeling is essential to optimize the performance of water distribution and wastewater collection systems. State-of-the-art models enable our experts to simulate real-world conditions, identify system bottlenecks, and test infrastructure improvements in a virtual environment. By simulating these dynamic scenarios, we empower decision-makers to anticipate, analyze, and mitigate system risks before they occur. Ardurra’s modeling services provide the critical insights needed to design regulatory-compliant, sustainable infrastructure for our clients as well as support them in proactively managing their utility systems.

Regulatory Permitting & Compliance

 Ardurra’s regulatory permitting and compliance for water and wastewater constitutes a critical, legally-mandated framework designed to protect public health and environmental integrity by regulating the treatment, transport, and discharge of water resources. Compliance involves maintaining stringent, approved standards through rigorous monitoring, reporting, and maintenance of treatment and conveyance facilities, ensuring that all treated effluent discharged into navigable waters or sent through the distribution system meets or exceeds safe, legal parameters. We staunchly represent our clients’ interests, expertly guiding them through relevant policy, risk, cost, technical, public acceptance, and service objectives.

Utility Master Planning & Asset Management

Ardurra applies strategic, data-driven processes to ensure long-term infrastructure sustainability, reliability, and cost-effective operations. Our proven approaches extend the useful life of equipment and facilities that are essential to public health. We focus on proactive maintenance to prevent failures that could trigger costly emergency repairs or permit violations. Our comprehensive capital improvement plans are phased and aligned with your budget; we include energy optimization and resiliency factors that can often provide funding opportunities.

Emerging Contaminants (PFAS)

Ardurra is on the forefront of researching, developing and implementing solutions and treatment processes and strategies to address emerging contaminants, including forever chemicals such as polyfluoroalkyl substances (PFAS). Our research includes quantifying concentrations and classifying PFAS in source waters across the country to determine regions most affected by PFAS. We have conducted studies and pilot tests to identify the appropriate treatment processes to reduce PFAS to cost-effectively meet the EPA’s limits.
