40 Years of RJN Innovations (Part 3 of 3) In celebration of our 40th anniversary, RJN is reflecting on its contributions to the collection systems industry as a pioneer of new techniques and early adopter of breakthrough technologies for greater accuracy and efficiency.
In the early 1980s, RJN made a discovery during a sewer study in Fayetteville, Arkansas. The same drainage basin was inadvertently smoke tested twice, once by a consultant using a single blower and once by RJN using dual blowers. The results could not be ignored: 69 defects were found during single blower testing and 234 with dual blowers.… Read the restContinue reading
40 Years of RJN Innovations (Part 2 of 3) In celebration of our 40th anniversary, RJN is reflecting on its contributions to the collection systems industry as a pioneer of new techniques and early adopter of breakthrough technologies for greater accuracy and efficiency.
By the mid-1970s, the study of sewer system hydraulics and stormwater drainage were based on the century-old Manning’s Formula and Rational Method, and other core principles of hydraulics, such as Bernoulli’s Equation which was older still. The EPA had released its Storm Water Management Model (SWMM) earlier in the decade, which refined upon these principles, and computers were available to run complex dynamic models of sewer networks.… Read the restContinue reading
40 Years of RJN Innovations (Part 1 of 3) In celebration of our 40th anniversary, RJN is reflecting on its contributions to the collection systems industry as a pioneer of new techniques and early adopter of breakthrough technologies for greater accuracy and efficiency.
Back in the 1970s, the Clean Water Act and the microcomputer were both brand new. Civil engineers were in hot demand, with municipal clients eager to conduct Sewer System Evaluation Surveys (SSESs) to qualify for 75% federal grant funding to build wastewater treatment facilities. RJN Group, Inc. opened its doors in July 1975 and was performing sewer studies, but with the ultimate intent of developing new engineering methodologies to inspect, analyze, and rehabilitate sanitary sewer systems.… Read the restContinue reading

June 26, 2015—In Part 1, Vincent Bergl, P.E., discussed whether or not conserving water on rainy days could help prevent overflows in separated sewer systems. Here he explores combined sewer systems, which were primarily constructed in the early twentieth century when the goal was to convey both untreated sewage and stormwater to the nearest river or stream as quickly and cheaply as possible.
By design, combined sewers are significantly larger than sanitary sewers, so in a well-functioning combined sewer system, pipeline capacity is rarely the primary constraint. Rather, it’s the capacity of downstream treatment facilities that’s easily exhausted. Most urban treatment plants were built prior to the Clean Water Act.… Read the restContinue reading
June 12, 2015—Project Engineer Vincent Bergl, P.E. recently caught up with an old college friend who mentioned she was refraining from using water during heavy rains so that she wouldn’t contribute to overloading the sewer system. It sparked an impromptu lesson on urban hydrology (lucky her), and after hearing similar concerns expressed elsewhere, Vinnie decided his thoughts were worth sharing:
No one welcomes beach closings or basement backups, but can water conservation during storms prevent sewer overflows? The answer is maybe sometimes, but not really, depending on context. Let me explain.
SEPARATED VS. COMBINED SEWERS. Let’s start by distinguishing separated from combined sewer systems because the difference affects the answer.… Read the restContinue reading

We are using a simple surcharge gauge monitoring system to measure sewer flows and alert us when manholes surcharge and/or overflow. This monitoring system does not require equipment to be installed within the pipe where it is at risk for fouling by debris. Furthermore, installation of the equipment is easy and quick.
The surcharge gauge consists of a pressure sensor that measures depth of flow in the manhole and a telemetry device to send data to a server. This photo shows the monitoring equipment when looking down into the manhole.
The pressure sensor is attached to a bucket installed on the manhole bench.… Read the restContinue reading

As a leading expert in wastewater collection systems, one of RJN’s strongest specialty services is the identification of inflow and infiltration (I/I) sources in sanitary sewer systems. Using a combination of smoke testing, manhole inspection, dye flood testing, building inspection, and sewer televising, detailed data on the locations and characteristics of I/I sources are collected in the field and then compiled in ways that are useful for analyzing their aggregate effects on the collection system.
A key component of this analysis and of any sanitary sewer evaluation survey (SSES) is the flow quantification process — that is, the estimation of the total flow that would be contributed by the identified I/I sources during a wet-weather event.… Read the restContinue reading
RJN Group field technicians were recently in Memphis, Tennessee performing smoke testing on the City’s wastewater collection system. While performing smoke testing it is not unusual for curious residents to come out of their house to ask questions from our field staff about what we are doing.
In one particular neighborhood that resident ended up being A C Wharton, Jr., the Mayor of Memphis, he saw RJN smoke testing and stopped to say “Hello”.
RJN staff included in the picture with Mayor A C Wharton, Jr. are Field Crew Leader, Joseph Colley; Field Crew Chief, Preston Fisher; Field Technicians Jamie Riggs, Rick Benson, and Frank Baumgartner; and two of our temp workers.… Read the restContinue reading
All across our nation, 2013 was a year during which extreme weather never seemed to take a break. It started with the northeast still recovering from Snowicane Sandy, and the disasters only mounted from there. Blizzards, downpours, floods, and November tornadoes would all top headlines before the year was out, and two months into 2014, the U.S. has already suffered a severe drought, an early wildfire season, and multiple visits from something called a polar vortex.Continue reading
In November 2013, we posted an article that was written covering the City of Hot Springs efforts in addressing and correcting deficiencies in their wastewater system under a Consent Administrative Order (CAO). The article also describes the Sanitary Sewer Evaluation Study (SSES) that is being performed by RJN Group.
The City recently released a terrific informative video that will visually tell you the story of their efforts as well.Continue reading
Safety for Cold Weather
This winter has been brutal and that is putting it mildly. Even though the temperatures are at record setting lows and the snow is piling up to heights well above our vehicles, RJN field crews still need to get out there to perform field investigations for our clients.
To prepare our field crews for the cold weather (and at times Arctic Blasts), we stock every field vehicle with an emergency kit, blankets, and hand warmers. Each crew member is supplied with snow pants, winter jackets, winter coveralls, latex coated winter gloves, and full face masks.
We don’t stop at just providing the crews with the right materials.… Read the restContinue reading
The American Public Works Association (APWA) Chicago Metro Chapter Suburban Branch recently recognized RJN’s Atrium Force Main Replacement Project with the City of Elmhurst as the Project of the Year Award Winner in the Environment Less than $5 Million Category.
The Elmhurst Atrium Force Main Replacement Project was the design and trenchless construction of 1,350 feet of sanitary forcemain in Eldridge Park, a former landfill. The City of Elmhurst had experienced numerous breaks on an 8” diameter 6,500 foot sanitary forcemain adjacent to Salt Creek, a major tributary of the Des Plaines River.

The City of Elmhurst had experienced numerous breaks on a 60-year-old, eight-inch-diameter, 6,500-foot sanitary forcemain adjacent to Salt Creek, a major tributary of the Des Plaines River. All the breaks were concentrated in an area of Eldridge Park, a former landfill in the southern part of the City. Owing to the number of breaks, the Illinois Environmental Protection Agency (IEPA) issued a violation notice to the City requiring that they construct a replacement within two years.… Read the restContinue reading
In August 2008, the City of Hot Springs was placed under a Consent Administrative Order (CAO) by the Environmental Protection Agency (EPA) due to violations primarily related to wastewater overflows in the collection system.
Wastewater system overflows are typically caused by pump station failures, inadequate pipe size, piping degradation, and from insufficient maintenance and repair over time.
The CAO required that the city:
- Eliminate dry weather overflows by January 2011. Dry weather overflows typically result from pump station mechanical or power failure.
- Eliminate wet weather overflows by January 2018. Wet weather overflows typically result from inflow and infiltration of stormwater, thereby exceeding system capacity during heavy rainfall events.
