The goal of this work is to present a suitable tool or model for the evaluation of the internal landfill water discharge, in relation to the basic design parameters of internal landfill drainage system and other processes. De Zeeuw-Hellinga’s drainage theory fulfils those requirements. De Zeeuw-Hellinga’s drainage intensity factor takes in basic design parameters of internal landfill drainage system and also hydro-physical properties of the collected waste. The drainage theory calculates with landfill internal water recharge to the drainage system within a certain time interval. In practice this method was successfully verified in a sanitary landfill of solid domestic waste in Osecna (a region near Liberec, Czech Republic). The comparison of the real data of the measured values of the internal landfill water discharges with calculated values, demonstrated eligibility of the use of De Zeeuw-Hellinga drainage theory as a good instrument for approximation of the internal landfill water discharges. This tool needs only a minimum of information and can be applied for the evaluation of basic design parameters of the internal landfill drainage system, for the design of the landfill reservoir capacity, and also for description of the landfill hydrology processes.
