Priority

Description Place Parshall flume(s) directly downstream of the grit tank channel isolation valves including ultrasonic measuring. This will require channel modifications, flume and sensor installation and programming into the headworks PLC. Justification Flow measuring was changed from a Parshall flume to an in-channel area velocity sensor/meter in the last plant upgrade. That sensor/meter failed and subsequent efforts at flow measurement lack staff confidence in being greater than 80% accurate. Parshall flumes have been used in the wastewater industry for decades with 99+% accuracy and confidence. Total Project Cost: $251,000 Status Active
