Leachate Modelling
Forecasting leachate generation, treatment costs, and infrastructure requirements across the full landfill lifecycle — from active filling through closure and long-term aftercare — under multiple climate scenarios.
OVERVIEW
Our leachate models forecast water balance and leachate generation across every stage of a landfill's operational life. The models dynamically track how cells transition through stages — from initial construction and active filling, through interim and final capping, to long-term rehabilitation — reflecting how leachate volumes change as the site evolves. Climate data is integrated directly into the model, allowing forecasts under current conditions and future climate scenarios to support infrastructure planning that accounts for changing rainfall patterns. The outputs are designed for practical decision-making: quantifying treatment costs, sizing storage and treatment infrastructure, comparing onsite versus offsite disposal options, and feeding directly into financial provisions and cost recovery models.
KEY BENEFITS
- Forecast leachate volumes across the full landfill lifecycle — filling, capping, closure, and aftercare
- Dynamic cell staging reflects real operational sequencing as cells open, fill, and close over time
- Climate scenario analysis accounts for changing rainfall and evaporation patterns
- Compare treatment options — onsite treatment versus tanker disposal to STP
- Size leachate storage, collection, and treatment infrastructure with confidence
- Direct integration with rehabilitation provision and cost recovery models
- Transparent methodology with clear audit trail for regulatory and financial reporting
Monthly water balance components — precipitation partitioned into runoff, evapotranspiration, and leachate generation.
