Project Limits: Various locations throughout the Village, but a significant number of manholes will be treated in the in the area bordered by Wilson Avenue (north), Edgewood Avenue (west), Westmore/Meyers (east) and Roosevelt Road (south).
The Purpose of the Project is: To rehabilitate sanitary manholes that are deteriorating structurally, subject to corrosive hydrogen sulfide gases (H2S), or have inflow and infiltration (I & I) issues. I & I is groundwater and/or storm water that flows into a dedicated sanitary sewer.
Project Schedule: May - October
Traffic Impact: Very low impact. There will be short term lane reductions at some sites.
Notify Me: Residents /Business Owners within construction areas are highly encouraged to sign-up for Notify Me. Notify Me will provide a more specific timeline as to when the structure in the vicinity of the property will be repaired. To receive timely updates regarding construction your area sign up for Notify Me.
Newsletters & Notices: One notice will be mailed to affected residents and businesses to inform you of a structure in the vicinity of your 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 as 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.
