Specifications include, but are not limited to: a. The intent of this Proposal is to establish a contract to perform temporary System Wide Flow Monitoring (system flow and rain) for the City of Kingsport. 1) Flow Monitors. 35 locations to be monitored for a minimum of 60 days (30 days of additional time may be required if sufficient rain events are not logged during the monitoring period) 2) Rain Gauges. 14 temporary rain gauge installations (timing to be coordinated with Flow Monitoring). Flow monitoring services shall include site selection, equipment installation and calibration, operation, maintenance and data collection for each flow monitoring location listed on Attachment A for a minimum period of 60 days beginning on or about February 3, 2020. Flow monitoring devices must use solid-state electronics with the capability of measuring and recording wastewater depth and mean velocity at five-minute intervals. Ultrasonic Doppler technology (or equivalent) is acceptable for measuring velocity. Pressure transducers or ultrasonic technology (or equivalent) is acceptable for depth measurements. CONTRACTOR shall recommend the most suitable flow monitoring equipment/technology to fully meet the temporary flow monitoring objectives. ENGINEER shall approve the final selection of the proposed flow monitoring equipment
