Cleaner Water.
Healthier Communities.

Clean water matters. It sustains ecosystems, meets regulatory requirements, and keeps communities healthy. We help you achieve all three.

Our approach combines advanced modeling with practical design to address the full range of water-quality challenges: nutrients, sediments, and emerging contaminants. We work at every scale, from retrofitting urban stormwater systems to restoring entire watersheds. The solutions we recommend don't just reduce pollutants. They often restore habitat, reduce flooding, and build long-term resilience.

Whether supporting MS4 compliance, implementing green infrastructure, or developing nutrient management strategies, we help communities achieve measurable improvements in water quality and long-term sustainability.

  • Watershed and water quality assessments
  • Nutrient management strategy development
  • Stormwater control measure (SCM) design and retrofits
  • Stream, wetland, and riparian buffer restoration
  • Green infrastructure and nature-based solutions
  • NPDES MS4 program evaluation and compliance support
  • Water quality monitoring and data analysis
  • Capital improvement planning for water quality projects

Our approach blends science, engineering, and stakeholder engagement. We start with comprehensive data collection and modeling to identify cost-effective strategies, then design solutions that integrate regulatory compliance with ecological uplift. By leveraging innovative practices and proven methodologies, we deliver projects that improve water quality, enhance community resilience, and align with local priorities.

  • Watershed Treatment Model (WTM) and PCSWMM water quality modeling
  • Nutrient and sediment reduction crediting protocols
  • Low Impact Development (LID) and green infrastructure design
  • Stream and wetland restoration engineering
  • Regulatory compliance for TMDLs and MS4 permits
  • GIS-based screening and site prioritization for SCM retrofits

Turning Water Challenges Into Lasting Solutions

Access to safe drinking water is the cornerstone of a thriving community. At Ardurra, we combine technical excellence with innovative strategies to help clients navigate the complexities of water supply and treatment: from aging infrastructure and emerging contaminants (including PFAS and microplastic), lead and copper rules to climate change and evolving regulations. With proven expertise and a forward-thinking approach, we transform challenges into resilient, sustainable solutions that protect public health, foster economic prosperity, and ensure reliable water supplies for generations to come.
