Abstract: The invention includes a system for monitoring the performance of an automatic dosing siphon utilized in reservoir which is a part of a wastewater treatment system. The siphon includes a bell type cover, a fluid trap having one leg extending upward into the bell, and an outlet discharge pipe connected to said trap. A flow detect switch is located in the discharge pipe. Upon siphon activation the switch is opened and a countdown timer is reset. After draining the reservoir, the switch closes and the timer starts counting down a predetermined time period. If the siphon doesn't activate, time expires and an alarm is triggered. A second system utilizes a solenoid drain valve located above the outlet portion of the siphon trap such that upon time expiring the valve opens, the tank drains, and the timer resets. The valve automatically reprimes the siphon. The system continues to monitor the siphon and initiates an alarm upon subsequent siphon failures.
