The treatment of wastewater to alleviate our freshwater needs and protect the environment at a reasonable cost is a major problem in the world today. The application of partially-treated wastewater to the land may be one method of solving this problem. Land application is neither a new concept, nor one that will solve all treatment problems, but it is likely to play an ever-increasing role in water pollution control planning. The Water Resources Institute at SDSU sponsored the project in its initial year of 1974. During this time much of the construction of the three infiltration percolation basins was completed. The EPA then provided funding in 1975 and the unit began operation in June of that year. The areas of investigation were divided into several parts. The objective of this portion of the project were: 1. To determine the ability of the infiltration percolation pilot unit to produce an effluent that will satisfy present and future effluent standards in terms of biochemical oxygen demand, suspended solids, ammonia nitrogen, and fecal coliforms. 2. To compare effects of the type of basin surface and hydraulic loading rate on the quality of the renovated water. Other areas of the EPA project included: determination of the hydraulic loading rates acceptable to the soil, determination of the nitrogen and phosphorous removal accomplished within the soil, and establishment of limitations of the system due to climatic conditions.
