Results are presented from an investigation of the efficiency of three chlorination schemes used for the disinfection of municipal wastewater treated by overland flow. In experimental studies conducted during the summer and fall of 1984 at the University of California, Davis Overland Flow Field Research Facility the levels of disinfection achieved by chlorinating primary effluent and oxidation pond effluent both before and after treatment by overland flow were compared. Additional studies monitored the performance of overland flow slopes treating primary effluent and oxidation pond effluent. Based on the findings, overland flow treatment of primary effluent followed by chlorination is recommended as a reliable and efficient treatment process for municipal wastewaters.
