No two Wastewater Treat Plants are exactly the same. They may be structurally the same, or even built by the same contractor or engineer, but they tend to take on their own personalities. Each WWTP will react differently to any given set of variables or conditions. This is what makes them not only unique but even harder to trouble shoot. This is why historical data that includes temperatures changes, rain events, loading conditions, and flows are so important to help with trouble shooting. This information will help us understand how the plant reacts to certain conditions. Armed with these clues we are able to statistically determine what adjustments are needed.
