Project Profile: In Tulsa, Using Multi Sensor Inspection (MSI) Platform System Helps Provide Solutions

Like most cities across the U.S., the City of Tulsa is dealing with the maintenance and operation of an aging sanitary sewer infrastructure. One facet of the aging infrastructure of significant concern is the City’s vast array of large diameter concrete sanitary sewer interceptors.  The City was quickly finding it difficult to determine the remaining lifespan of a concrete interceptor from traditional close-circuit television (CCTV) methods alone.  This is when they reached out to RJN Group, Inc. for assistance with advanced pipe inspection technologies and RJN’s knowledge of utilizing these technologies to determine the Remaining Useful Life (RUL) of each section of concrete interceptor.… Read the rest

Project Profile: Major Stormwater Mapping Project Locates Many Previously Unknown Structures

At this point, you are probably very familiar with RJN’s capabilities when it comes to wastewater services, including condition assessments like manhole inspections, smoke testing, dyed water flooding, and building inspections as well as flow monitoring, hydraulic modeling, master planning, SSES, and remediation and design. What you might not know is that RJN can apply our impressive skill set and use of advanced technologies to stormwater systems as well.

For example, over the last three years, RJN has been using advanced technologies to map and assess the condition of the City of San Antonio’s stormwater collection system with stellar results led by RJN’s Stormwater Lead and Project Manager Noelle Gaspard, P.E., GISP, CFM.… Read the rest

Project Profile: For RJN and Richardson, Proactive Maintenance Is Key to Success

These days, it has become much more important to be proactive with underground infrastructure maintenance as opposed to reactive. Ultimately, it saves time and money to take preventive measures as opposed to fixing issues as they arise. One of the ways RJN is able to do this is by effectively using risk analytics to determine the best course of action for its clients.

Recently, RJN worked with the City of Richardson, Texas, to support its ongoing CMOM and master planning efforts by conducting a risk-based sewer study. The program focused on evaluating existing CCTV footage, identifying hydraulic capacity issues, and assessing the risk of asset failure.… Read the rest
