Saturated Rock Fill System Design & Field Performance Validation

project overview

Integrated Sustainability advanced the design and field performance validation of a semi-passive saturated rock fill system for contact water treatment. This included a detailed design basis memorandum for pilot-scale operations and a multi-month tracer test to evaluate groundwater pathways and flow dynamics.

project deliverables

• Prepared a pilot-scale design basis defining hydraulic targets, treatment objectives, and reagent dosing strategies.
• Established retention time requirements and identified supporting infrastructure needs, including mixing tanks and modular skid-mounted systems.
• Executed a bromide tracer test to evaluate groundwater flow rates and validate subsurface hydraulic behaviour.
• Measured flow velocities and confirmed stratified flow pathways and downgradient migration patterns within the treatment zone.
• Estimated effective porosity and saturated volume characteristics for the pilot-scale treatment area.
• Summarized pilot performance results and flow assessment data to support permitting activities and future full-scale system expansion.
