Frequently asked questions
Q: How far back do you look when reviewing data? Five years? Ten years? Will you miss changes in plant in last 2 years?
A: We typically look at the most data that we can. More data points reduce variability. If we know something happened—a large industry moved out, WWTF changed equipment—that we can document, then we look at data after that. For flow, we look at 30 years. But if we know a dam was removed, then we look at data since then.
