Abstract Treatment performance of three rapid infiltration basins receiving primary treated municipal wastewater is evaluated for optimum total nitrogen control using a series of manual operational techniques and by remote control computer operation. Three types of loading sequences were used; flood loading every three and one-half days, flooding daily and sprinkler system loading based on soil moisture sensors and computer analysis and control. The influent and effluent quality variations were increased substantially compared with previous studies. Under optimum conditions, sustained removals above seventy-five percent were achieved with values for individual weeks in the mid-eighty percent range. Nitrogen removals were somewhat less for the automated sprinkler loaded system with a maximum four-week average of sixty-five percent.
