Abstract: During the summer of 1979, wastewater was applied 10 times to the Deer Creek Lake, Ohio, land treatment site. Wastewater distribution on the ground during spray application is not uniform; some locations receive less than 70% and others more than 130% of the mean amount applied. The saturated infiltration rate ranges from moderately slow (0.6 cm hr^-1 after 1 hr) to slow (0.3 cm hr^-1 after 12 hours) and can be expressed by /≈ 0.6^-1/4 cm hr^-1. The underdrain flow rate increases approximately as the cube of time until 1 hour after the end of application and then decreases as the reciprocal of time squared. The rate and amount of drainage increases with an increase in the initial soil water content and can be predicted from soil tension measurements. It was possible to calculate the mass water budget at the end of a typical application to within 88% of the actual water applied.
