Abstract
A reservoir management system for a water reservoir having inlet and outlet piping and means for adding chemicals in controlled amounts to the water within the reservoir. One or more eductors are positioned within the water reservoir to mix and circulate water within the reservoir. A recirculating pump is located externally to the reservoir and has an inlet line that taps into the outlet piping from the reservoir. One or more sample lines remove test streams of water from the reservoir which are analyzed to determine the level of at least one of chemical in the test stream to provide a chemical-related signal. A controller receives the signal and compares the signal to a set point indicative of the level of chemical desired within the reservoir to maintain, increase, or decrease the amount of chemical added to the water within the reservoir in controlled amounts. A flow meter monitors the rate of flow into the reservoir and retention time of water and generates one or more signals to the controller as the rate of flow varies from a set point.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
