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 restContinue reading »

Flow monitoring is an initial step in improving your collection system. It helps you develop a plan for future field investigations while also prioritizing areas for study. Flow monitoring captures a clear picture of the hydraulic performance of a collection system. Flow meters, with the technology to record flow levels and flow velocity, are strategically placed throughout a system. Data is continuously recorded defining daily usage (base flows) as well as the system performance (peak flows) during rainfall/storm events.
How RJN’s Approach to Flow Monitoring
Saves Time and Money, Ensures Accuracy
Flow monitoring when done the right way with RJN – sending the results of constant real-time monitoring to a data group of experts who then analyze the data – is important mainly because it saves time and money.… Read the restContinue reading »
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 restContinue reading »

Designing large-diameter gravity sewer interceptors is challenging enough on its own, but there are often additional complications that can make completing these designs even more difficult: avoiding buried utilities. Try as we might, sometimes buried utilities can come as a surprise to the design engineer due to inaccurate, incomplete, or otherwise missing information concerning the location and depth of those facilities and more often than not, it is revenue-generating high-pressure gas lines and fiber optic cables. When this happens, the design engineer needs to be particularly resourceful in developing plans that mitigate, manage, and avoid these underground conflicts.
What makes this such a challenging problem is that the onus is on the design engineer to come up with an affordable and reasonable solution instead of making the utility company move their lines or cables.… Read the restContinue reading »
At RJN, we always stay abreast of the latest technologies in the industry. If there is a new technology available that can make our field investigation techniques more efficient, accurate, and cost-effective, then we will definitely pursue it by either acquiring it ourselves or collaborating with contractors who possess the new technology. In both cases, be it RJN or a contractor with whom RJN is working, the teams responsible for using the latest technology will be experts with it, able to maximize that technology’s capabilities.
But having access to the latest technologies and being trained on how best to use those technologies is not enough—experts like the engineers and technicians at RJN also need to exercise good judgment, strong strategies, and creative problem-solving to decide when using these new technologies would be most beneficial to our clients.… Read the restContinue reading »

Within a single study area, the rainfall levels can vary dramatically. For instance, one of RJN’s clients saw 1.56 inches of total rainfall in 50 minutes throughout the center of the study area, but during that very same 50 minutes, the eastern part of the study area had only .1 inches of total rainfall. Had RJN not been measuring at multiple rain gauge sites, the overall analysis of the entire study area would be both incomplete and inaccurate.
The video shown below depicts this rain event:
According to RJN’s Thomas Romza, P.E., “In this video, I enclosed the study area where we were flow monitoring.… Read the restContinue reading »

Numerous times in recent years, the federal government has attempted to address the problem of crumbling water and wastewater infrastructure. From funding assistance, to creating new offices to help communities, to conducting Senate hearings and publishing EPA reports, the federal government is aware of the problem and is working to figure out how best to solve it.
In January of 2015, the Obama Administration launched a new Water Finance Center at the EPA to assist cities and towns in securing funding and contractors for providing safe water, rebuilding sewer systems, and keeping rivers and streams clean. 1 Success of this new office remains to be seen, especially after recent problems surface such as the water quality in Flint, Michigan.… Read the restContinue reading »
Crumbling Infrastructure—Background and Scope
While it is easy to look at the staggering financial figures and wonder how our country could require upwards of trillions of dollars to solve these problems over the course of only a few decades, it is important to consider the scope of the work to be completed and possible solutions to the problems associated with the rising costs of crumbling water and wastewater infrastructure.
In July of 2013, a Senate hearing took place to discuss this issue. According to the testimony of Gerald E. Galloway, P.E., Ph.D., Glenn L. Martin, Institute Professor Of Engineering, University of Maryland, among the infrastructure that needs improvement are:
14,780 municipal waste water treatment facilities.… Read the restContinue reading »
The Rising Costs
Recently, negligence and possible misconduct of Flint government officials concerning the lead poisoning of that Michigan city’s water supply has brought crumbling infrastructure to the national spotlight. But this is not an isolated incident; every day, additional infrastructure problems and subsequent neglect are discovered in more and more cities across the U.S.
RJN Group, Inc., knows this too well, having been evaluating, studying, designing, and rehabilitating collection system pipelines for the last 40 years. Fortunately, from our perspective, there is no shortage of engineering workforce, talent, and solutions; unfortunately, on the other hand, there is a lack of funding in the industry to meet the dire needs of the crumbling infrastructure. … Read the restContinue reading »
RJN Group, Inc. has yet another option for manhole inspection in its growing portfolio of evaluative tools: It is called Panoramo SI, offered by IBAK, and it proves to be very helpful due to its technologically advanced capabilities.
