<p>A landfill (10) is lined with an impermeable liner material at (12) and filled with waste, such as household waste. When the landfill is full, it is capped by a cap (14). Degradation of the body of waste material within the landfill creates leachate liquid as a byproduct. Without intervention, the leachate will form a layer (16) of saturated waste material at the bottom of the landfill (10). An extraction well (22) allows leachate to be drawn from the landfill (10) by a pump (26). Injection wells (24) allow leachate to be reintroduced into the landfill (10). Various sensors (36, 38, 40) take measurements associated with the wells (24). Leachate delivery is controlled in accordance with the values obtained. The obtained values may include the leachate head in the well and/or the volume or rate of leachate delivery to the well and/or the elapsed time since commencement of leachate delivery to the well and/or the rate of dispersion of the leachate into the landfill from the well.</p> |
