Better information about your collection, water, and stormwater systems
Explore ClarityAdvanced Vibroacoustic Analysis (AVA) provides pipe segment condition data while your mains remain pressurized and in service. Prioritize repairs, rehabilitation, and replacement with measured condition data.
Download the AVA brochure to see how pipe segment condition data supports municipal repair and replacement decisions.
The service covers buried water distribution and transmission mains, not building plumbing.
Your pipeline’s age and leak history help establish assessment priorities, but they do not show the condition of each pipe segment. Before committing capital to replacement, you need to understand where deterioration is occurring and where pipe remains sound.
RJN’s AVA service uses KenWave’s Dynamic Response Imaging (DRI) to analyze how pipe sections respond to applied sound and vibration frequencies. The assessment provides condition data by pipe segment, with resolution as fine as six feet, rather than a single average for the full pipeline.
Use those findings to distinguish which pipe segments need attention from those that may remain in service. Substantiated condition data helps public works and utility leaders explain investment priorities to elected officials and the public.
RJN captures data using vibration sensors at accessible points along your network. Your main remains pressurized and in service during testing, with no shutdown or bypass system required.
Sensors record the pipe’s response to sound and vibration frequencies. Kenwave’s algorithms analyze those responses to identify variations in condition along the assessed main.
RJN engineers interpret the findings and present pipe segment condition in clear visuals. Use the results to prioritize further investigation, targeted repairs, rehabilitation, or replacement.
Your capital improvement program needs evidence to support which assets receive funding first. RJN engineers interpret AVA findings and integrate the condition data into your asset management plans, GIS, and Clarity, RJN’s data management hub.
Pipe segment findings help you evaluate targeted work alongside broader replacement needs. Because testing occurs while the main remains in service, you can gather condition data while maintaining water service to customers.
Share the water mains you are evaluating and the decisions your capital program needs to support. RJN can discuss how AVA condition assessment may fit your asset management plan.
RJN Group, Inc. is pleased to announce that the Bloomington City Council has approved an agreement with RJN to conduct a comprehensive water main condition assessment in Census Tract 59 utilizing groundbreaking AVA technology.
Our Partnership with Kenwave Solutions
Through our collaboration with Kenwave, RJN is proud to be the exclusive U.S. provider of AVA — bringing this revolutionary Canadian-developed technology to utilities nationwide.
How do you decide whether to spend $12 million replacing a 93-year-old water main or far less in targeted repairs? AVA can answer that!
