Tentative Start Date: Week of July 24th Tentative Completion Date: October 2017 Project Manager: Ray Schwab, Civil Engineer II Bid Opening: June 6, 2017 Bid Award: June 15, 2017 Contractor: National Power Rodding Awarded Contract Amount: $110,605.00 Funding Sources: Construction Fund
Project Limits: 30 manhole locations will be rehabilitated at various locations throughout the Village.
This Project Includes: Rehabilitation of sanitary manholes that are deteriorating structurally, subject to corrosive hydrogen sulfide gases (H2S), or have I & I (inflow and infiltration) issues.
After Hours: Lombard Police Department
Notify Me: Residents /Business Owners within construction areas are highly encouraged to sign-up for Notify Me. Through Notify Me Village staff will provide a more specific schedule as the contractor progresses.
Newsletters & Notices: One notice will be mailed to residents/businesses. The notification will inform residents/businesses that a structure in the vicinity of their property is part of the project and will be repaired sometime over the next sixty days.
Why is this project necessary? Just like any other asset structures deteriorate over their service life and need to be periodically maintained. By lining manholes, corrosion due to H2S is significantly reduced and the service life of the structure is extended. Grouting the structure serves to eliminate inflow and infiltration (I & I). I & I increases waste water treatment cost because all of the water entering a water treatment facility must be treated. Therefore as additional wastewater is treated, operational costs increase.
How does this benefit the Village? By rehabilitating the structure, two benefits are incurred. A) I & I are reduced and in turn treatment costs are reduced. B) Installing an epoxy lining system weathers the corrosive environment within a structure and therefore extends the service life of the manhole.
Will there be detours? There will be short term lane reductions and some parking spots may be utilized by the contractor during working hours.
7/24/2017 - The Contractor plans to start work on July 27th . The first structure to be addressed is located at N Vista and E Berkshire Ave. The second structure is located in a rear yard off of N Grace and E Berkshire.
