AWWA JAW30418 Journal AWWA - Using Regression Analysis to Project Pumpage

Journal Article by American Water Works Association, 12/01/1991

Full Description

The city of Austin, Texas, Water and Wastewater Utility has used regression analysis to project water pumpage. It is a reasonably accurate, easy to learn and use, and inexpensive technique; it does not require an unusual amount of data; the explanatory variables and regression results can be quickly checked for statistical significance; and the input data can be easily modified. The fact remains, however, that regression cannot completely explain a complicated, multifaceted process. Also, there are limits to refining the predictions. Three refinements introduced in Austin were the relationship between rainfall and pumpage, graphics, and dividing the time into months. Includes 11 references, tables, figures.
