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 rest
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.

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 rest
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.
