Achieving optimum output and return on mining projects requires balancing operational efficiency with the requirements of good environmental stewardship. We believe in the smart use of water during mining operations through attention to both the environment and the bottom line. INTERA offers specialized expertise in developing and applying system-level models and other quantitative tools that incorporate a project’s complete water balance and allow informed decision-making with respect to overall water management. Our group of civil, geotechnical, and geological engineers bring the capabilities to evaluate existing mine infrastructure and design and oversee the construction of new or expanded water, sediment, and waste control systems. We also excel in establishing optimized monitoring plans and systems for collecting the data necessary to maintain regulatory compliance.
