Capitalizing on Flow Monitoring with Trimble Raven Eye

WRA chose Trimble's Raven Eye for its durability and ability to survive harsh conditions, and also for its dependability in flow monitoring that works for both open channel and sewer flow measurement.


The Des Moines Wastewater Reclamation Authority (WRA) is the regional wastewater facility for the Des Moines metro area, providing water services to 18 metro area municipalities, counties, and sewer districts in the Des Moines area. WRA is an award-winning clean water agency, having received the National Association of Clean Water Agencies (NACWA) Peak Performance Silver Award ten consecutive times.

WRA has 110 flow meters placed throughout the metro area to assist in monitoring flows within the city’s water infrastructure network. They also use these flow meters to determine each community’s share of WRA expenses depending on the flows from different sections of the city.

Flow monitoring data is instrumental in tracking the inflow/ infiltration that comes from each community. The data collected is used to implement plans for reducing extraneous flows and informs various aspects of community development such as master planning and strategic planning initiatives for future growth.
