The City of Virginia Beach deployed an open channel flow monitoring initiative as part of a SCADA upgrade project that included the installation of new SCADAPak PLCs at 407 wastewater pumping stations.
McKim & Creed contracted with FloWav, Inc. to install, calibrate and maintain 65 permanent open channel flow meters. The City of Virginia Beach provided monthly flow data from all of its wastewater pumping stations and it was identified that 84 of the stations required the installation of permanent flow monitoring equipment. Nineteen of the stations were adapted with clamp-on style ultra-sonic force main meters and 65 of the stations required use of open channel flow monitoring equipment to accurately measure the monthly flows.
The FloWav RS-33u was the selected monitoring device, as it is capable of providing level, velocity and flow data through telemetry as well as 4 to 20 mA output.
The telemetry data is sent daily to McKim & Creed’s Enterprise server and McKim & Creed staff continuously reviews the data and directs a full-time dedicated field crew to maintain the equipment. McKim & Creed also replaced 3G modems with 4G modems to ensure faster speeds.
