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.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
