The initiatives were developed in response to some of the sector’s most significant challenges, including tightening regulatory requirements, funding constraints and limited space for new treatment processes. Based across California and Colorado, the pilot projects will inform future client solutions and contribute to Stantec’s wider innovation strategy.
Advancing solutions for PFAS in drinking water
Following the introduction of new, lower federal PFAS drinking water limits earlier this year, utilities are seeking improved treatment performance and operational simplicity. Stantec is testing combinations of filtration media to maximise PFAS removal while maintaining stable operations and reducing backwashing frequency. Early findings suggest that mixed-media approaches may offer higher removal efficiencies with fewer operational interventions.
Enhancing sustainable nutrient removal
Water resource recovery facilities continue to face increasing expectations around nitrogen and phosphorus reduction. Stantec’s process-intensification programme uses a 40-foot modular treatment system fitted with advanced instrumentation to evaluate a range of nutrient-removal strategies. The research aims to reduce energy use and chemical requirements while maintaining high-value nutrient removal, providing scalable solutions for facilities with limited space or tighter discharge limits.
Improving foresight with machine learning
Stantec has also developed a machine-learning model capable of forecasting influent flows to water resource recovery facilities up to seven days in advance. Tested at 30 sites across the United States, the model achieved more than 85% accuracy using only three years of historical data and publicly available weather information. The predictive tool is expected to support staffing planning, operational adjustments and real-time decision-making.
This influent-flow model is the first in a growing suite of digital tools designed to complement Stantec’s PFAS and nutrient-removal research. By integrating findings across research streams, the company aims to help utilities strengthen resilience and respond effectively to emerging operational and regulatory pressures.
Supporting innovation in utility operations
Stantec has long supported utilities with research and technology development across the water sector. Through these new programmes, the company is seeking to help clients enhance environmental performance, strengthen public health protection and plan more effectively for future challenges.
