Leachate Head definition
Leachate Head means a pressure head on the leachate liner.
Leachate Head means the depth or height of leachate accumulated on the impervious layer beneath the landfill (i.e. geomembrane, engineered clay, other bottom liner, or natural aquitard). Leachate head, as discussed in guidance Section V.A., does not account for the depth of leachate in manifold trenches and sumps.
