RJN Engineers Presenting at WATERCON 2017 on March 22

Wheaton, Ill., March 16, 2017 - RJN Engineers Michael Young, P.E., and Owen Dean will be presenting at WATERCON 2017 on March 22, 2017, at the Crowne Plaza Hotel in Springfield.

Details about these presentations are as follows—
Presentation Title: The $4 Million Subdivision: The City of Joliet Solution to the Backyard Utility Easement Problem
Date: Wednesday, March 22, 2017
Time: 9 AM
Presenters: Allison Swisher, P.E., Civil Engineer II, City of Joliet, and Owen Dean, Staff Engineer, RJN
Location: Collections Track - Ruby Room, Crowne Plaza Hotel, 3000 S. Dirksen Parkway, Springfield, Illinois 62703
Description: The City of Joliet was looking to prevent emergency backyard repairs in the Haldemann Terrace Subdivision. Many of the water and sewer mains in need of repair were located in backyard utility easements with overhead electrical. To work around this issue, RJN and the City of Joliet decided to relocate the water main and rehabilitate the sewer mains. During water main relocation, homeowner education was critical. Approximately 8,500 LF of new 8-inch ductile iron water main was installed in the road right of way while backyard water mains were abandoned. During the sanitary sewer rehabilitation, RJN conducted SSES investigations and developed rehabilitation design. Overall, the total cost of this water main relocation and sewer main rehabilitation was a little more than $4 million, a price well worth it to put an end to emergency backyard repairs and resident dissatisfaction.

Presentation Title: Utilizing Storage to Supplement Flow Reduction and Reduce Basement Backups
Date: Wednesday, March 22, 2017
Time: 10:30 AM
Presenter: Michael Young, P.E., Vice President, RJN
Location: Collections Track - Ruby Room, Crowne Plaza Hotel, 3000 S. Dirksen Parkway, Springfield, Illinois 62703
Description: Following numerous spring storm events, the Village of Wilmette experienced extensive basement backups. Data from flow monitoring showed that the primary cause was reverse flow from the downstream interceptor. The recommended plan included installing a check valve on the existing sewer to stop the reverse flow, a pump-over lift station, and a 5.5 million gallon underground storage tank to hold excess flows when the discharge rate is limited. For a quick turnaround, the Village elected to use a design-build procurement process. RJN Group and Boller Construction formed a joint venture to provide comprehensive design and construction services. The project was completed in November 2015 ahead of schedule and under budget. Village residents benefit from both basement backup protection and an improved park facility.

In addition, RJN staff will be in the Exhibit Hall at Booth 419 to discuss municipal infrastructure solutions with conference attendees.
