Numerous large drainfield/mound systems have been proposed in Minnesota. These systems are popular because of the apparently low design, construction, operation and maintenance costs. However, design costs may be higher than expected due to the quality and quantity of data required. Criteria for individual on-site systems has been improperly applied to large systems in Minnesota. Specific site evaluation related concerns such as hydraulic operation and contaminate transport have not been adequately addressed when locating large systems. Further, the cost to perform the site evaluation will likely be much higher than the cost associated with an individual on-site system. Several evaluation techniques are discussed with respect to specific site proposals. Direct and indirect data collecting methods, and modeling techniques are discussed for three geologic settings.
