Forecasting Onsite Soil Absorption System Failure Rates

摘要

A review was made of four previous statistical studies of onsite soil absorption system failure rates in four different areas of the United States. From the data base a series of forecasting techniques were developed with varying levels of accuracy for use by facility planners in evaluating comparative costs of alternative plans for pollution abatement in small communities. The required input data and expected level of accuracy to be expected for each forecasting method is also provided.
