| Description | The purpose of this guide is to provide permittees with detailed descriptions of a few of the easiest or most common methods for taking flow measurements, if they choose to manually collect the data on their own. The intent is to assist permittees in understanding how to meet the permit requirements in a manner that is simple yet also accurate enough to meet Ecology’s needs. Other methods, not described in this guide, such as hydrologic models, in-pipe flow meters, calculations based on pump usage, automated flow devices, and others could also be used. Any flow estimating method that meets the intent of the permit would be accepted by Ecology. |
