Septic system including control and monitoring system
A method of operating a septic system to facilitate maintenance and avoid damage to property and/or the environment. A septic system that collects and monitors data to provide information to a user about the nature of a problem condition, or to warn a user of potential problems in advance, or to recommend courses of action to avoid costly repairs, or property damage, or damage to the environment.
1. A septic system comprising:
a septic tank configured to receive sewage from a structure;
an effluent receiving area;
a pump configured to move the sewage from the septic tank to the effluent receiving area; and
a control and monitoring system configured to:
operate the pump to begin pumping the sewage from the septic tank to the effluent receiving area when a fluid level in the septic tank reaches an upper pump level setting, and continue pumping until the fluid level in the septic tank falls to a lower pump level setting, at which point pumping is discontinued;
measure one or more performance metrics comprising at least one of the following:
an elapsed time of pumping from the upper pump level setting to the lower pump level setting; and
a number of events of pumping from the upper pump level setting to the lower pump level setting; and
alert a user of a condition of the septic system based on the one or more performance metrics exceeding a predetermined setting.
2. The septic system of claim 1 , wherein the septic tank comprises a first chamber and a pump chamber, and wherein the pump is disposed in the pump chamber.
3. The septic system of claim 2 , wherein the fluid level associated with the upper pump level setting and the lower pump level setting is measured in the pump chamber of the septic tank.
4. The septic system of claim 1 , wherein the one or more performance metrics further comprises an electrical current used by the pump when pumping from the upper pump level setting to the lower pump level setting, and wherein the septic system further comprises a processor configured to store data regarding the one or more performance metrics, and to alert the user when the one or more performance metrics exceeds the predetermined setting.
5. The septic system of claim 4 wherein the processor is further configured to calculate additional information based on the one or more performance metrics.
6. The septic system of claim 5 wherein the additional information calculated by the processor comprises one or more of an average value, a maximum value, a minimum value, and an event counter associated with the one or more performance metrics.
7. The septic system of claim 6 wherein the additional information about the one or more performance metrics further comprises identifying an alarm condition based upon a variance of the one or more performance metrics from the average value, the maximum value, the minimum value, the event counter, or a logical combination thereof, wherein the variance is greater than a predetermined threshold.
8. The septic system of claim 1 wherein alerting the user of the condition of the septic system comprises providing an audible alarm.
9. The septic system of claim 1 wherein alerting the user of the condition of the septic system comprises providing a visible alarm.
10. The septic system of claim 9 wherein the visible alarm comprises one or more of the following: a colored light, a code, and a text description.
