Findings are summarized of surveys at three winter sports areas to determine basic wastewater characteristics and recommend criteria for use in the design of treatment facilities. The tree sites selected were Crystal Mountain Ski Area near Mt. Rainier National Park, Washington, Timberline Lodge on Mt. Hood, Portland, Oregon, and Bachelor Butte Ski Area, Oregon. The quantity of various wastewater parameters discharged is a linear function of number of full-time employees, and either or both total visitors and overnight guests depending on the facilities. This relationship was vertfied by multiple linear regression analysis techniques. Statistically significant but highly variable relations were developed for COD, BOD5, suspended solids, total Kjeldahl nitrogen, and total phosphates. It is recommended that the maximum value of the 95 percent confidence limit be used in selecting design values. Methods for estimating design organic loading and design solids loading were developed.
