This blog is written by RJN employees with the purpose of giving people an inside look at our collection system projects and the services that we provide. We also want to tell stories involving our office activities and charity efforts.
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.
On September 5, the Greater Chicago Food Depository (GCFD) held the seventh annual aCANemy Awards gala at Chicago’s Merchandise Mart to honor the most creative, impressive, popular, and valuable entries in this year’s CANstruction Chicago design-build competition. The gala is not only a chance to reward the participants in the competition, but it is also a fundraiser and a flagship event to kick off GCFD’s Hunger Action Month.
RJN’s Central Operations are expanding with the addition of seven (7) new employees. Our
Central Operations consists of Illinois, Iowa, Minnesota, Michigan, and Wisconsin. In the last year there has been a significant rise in workload and the higher number of projects is expected to remain a mainstay for quite awhile for this office. The new positions include a GIS Technician, an Operations Assistant, three Civil Designers, a Project Manager, and a Senior Project Engineer.
In the role of Project Manager and Field Manager, Joe Sullivan will be responsible for business development and project management duties for SSES (Sewer System Evaluation Study) projects, flow monitoring, manhole rehabilitation, sewer cured-in-place pipelining (CIPP), and field services.… Read the rest
As the host chapter, the Chicago Metro Chapter of APWA worked for over three years to help bring the event to fruition, and they relied upon the help of volunteers from the local public works and engineering communities to make the conference a success. … Read the rest
This summer, for the seventh time in the seven years of the event’s existence, the RJN Wheaton, IL office participated in CANstruction Chicago, a friendly competition among Chicago-area engineers and architects benefiting the Greater Chicago Food Depository (GCFD). If you live in the Chicago area, the 20 entries from this year’s competition remain on display at the Merchandise Mart until September 9, and the aCANemy Awards Gala (tickets available!) will take place this Thursday, September 5.
For those who have never participated in a CANstruction event or seen their often-stunning products first-hand, the objective of CANstruction is pretty simple: participating teams raise a bunch of money to buy tons (literally) of cans that they form into structures, sculptures, murals, concept pieces, or whatever best describes each massive creation.… Read the rest
This summer has not only brought along warm weather (or blazing hot depending on your location) and sunshine, but also new certifications and registrations for RJN engineers, designers, and analysts.
GIS Analyst, Matt Boyle, recently earned his GISP Certification. A GISP is a certified geographic information system (GIS) Professional who has met the minimum standards for educational achievement, ethical conduct, and professional practice as established by the GIS Certification Institute (GISCI). As a GISP, Matt had to go through an intense evaluation process where his professional background was reviewed the GISCI. The GISCI is comprised of leading non-profit associations (AAG, NSGIC, UCGIS, GITA, & URISA). … Read the rest
How does one descend a manhole when its opening is nine feet above the ground but the tripod is only seven feet tall?
RJN’s Tulsa office recently faced this dilemma while doing manhole inspections for the City of Tulsa, Oklahoma. Inspections of above-grade structures are always challenging, but when the rim is above the inspector’s head, some specialty equipment and a little creativity are necessary to get the job done. In addition to the height of the manholes, the configuration of the structures created another obstacle. The openings were typically toward the corner of the flat top slab where the tripod legs could not straddle the opening and maintain level footing on the slab, and highly uneven tripod legs make for a very un-sturdy and unsafe setup.… Read the rest
As you might have noticed from some of our blog posts, much of our work revolves around the rain. We indicated in our last update (“A new one for the record books”) that it can help drive communities to invest more in their collection systems, and in another (“Will it Rain?”) that it helps us identify problem areas with flow monitoring.
Is there, then, a time when, as collection systems engineers, we just don’t want that rain to fall?
Yes; and that time is fast approaching. We call it smoke testing season.
For those of us in the Chicago area who have worked in wastewater, stormwater, public works, and collection systems management for a number of years, there are certain dates that stick in our minds: October 13, 2001; September 13, 2008; July 24, 2010; July 23, 2011. Some of us know them better than our relatives’ birthdays or our biggest personal milestones.
To our friends and companions, these dates probably mean little, but to us, they mean rain. Rain, and lots and lots of it.
We can now add April 18, 2013 to the list.
In some Chicago suburbs, it rained more than six inches Thursday morning, and few places in Cook or DuPage Counties saw less than four inches come down.… Read the rest
