Water Main & Street Work to Begin on July 15 on Clark, Austin & Keeney Streets
Starting July 15 for eleven weeks, the city will be contracting the water main replacement and street resurfacing CIP II project, which consists of three street segments on Clark, Austin and Keeney Streets. Parking restrictions will be required in order to complete the work. Any sprinkler system should be identified and marked with a flag by the property owner prior to the start of construction to prevent damage to the sprinkler system.
This project includes replacement of the existing deteriorated water main with new ductile iron pipe as well as replacement of the existing water services.
The street resurfacing portion of the project involves curb replacement, as needed; roadway base repair; replacement of asphalt surface from curb to curb; and selected replacement of sidewalks and driveway aprons.
As part of this project, the sidewalk on the west side of Chicago Avenue will be widened to ten feet between Church Street and Clark Street. The water main work and street resurfacing are part of the cty’s continuous program to renovate and improve the water distribution system and roadways throughout the community. The funding for the project will be from the city’s Water Fund and Capital Improvement Fund.
The locations which have been included as part of this contract, in sequence of construction, are:
Construction will begin the week of July 15 on Clark Street with the entire project expected to be fully completed by the end of September. The actual date when construction is planned for each street will be noted on the temporary NO PARKING signs posted 48 hours prior to the start of work. The construction activities will create some inconvenience for abutting residents, but workers will attempt to minimize these inconveniences. Construction zone daytime NO PARKING restrictions will be intermittent throughout the duration of the project; evening and night time parking (5:00 p.m. to 7:00 a.m.) will always be available. Street sweeping and/or neighborhood parking restrictions will be waived for a one-block radius around the construction zone when temporary daytime NO PARKING is in effect.
Sewer Work Set to Begin July 22 on Prairie Ave.
The City of Evanston Utilities Department has contracted with Insituform Technologies USA, LLC (Insituform) to rehabilitate approximately 2,175 feet of 48” diameter brick sewers on Prairie Avenue between Central and Grant Streets. The work will take place in stages from July 22 to August 15, weather permitting. Parking restrictions will be required in order to complete the work.
The rehabilitation work includes installing a cured-in-place pipe (CIPP) liner inside the existing sewer main. When completed, there will be a new fiberglass pipe installed within the old existing brick sewer. This process is generally less disruptive and the work can be completed much faster than if the sewer were excavated and replaced.
The resins used in the lining process are not new. They are the same resins used in the fiberglass industry for many years. These resins contain a chemical called styrene that hardens when heated. Although styrene is not a pleasant odor, it is not dangerous at the levels at which people can detect it. If a resident smells the styrene while the contractor’s personnel are working in the area, do not be alarmed. To help prevent the smell from occurring in buildings and houses, pour a gallon of water into each basement floor drain. This keeps the “trap” full and prevents sewer gases from coming into the buidling/house. Because the water in the drain trap evaporates, this practice should be done regularly.
The sewer segments will be rehabilitated starting at Central Street and working south towards Grant Street. In general, the contractor’s work area will be at the manholes located on Prairie Avenue at the alleys mid-block between the east/west streets. No parking will be allowed in and around each work area for 2 to 3 days including nights. Residents are asked to please pay particularly close attention to the city signs to minimize the impact to traffic.
On each block, the contractor will insert the liner through the manhole to rehabilitate the sewer to the north and then the next day insert the liner through the manhole to rehabilitate the sewer to the south. It will take approximately 16 hours each day from the time they begin the installation of the liner until the liner is fully installed. When the liner is inserted into the sewer main in front of each property, it will seal the building/house sewer service connections and prevent them from flowing into the public sewer. The contractor will perform by-pass pumping of the sewer services as necessary to prevent any sewage from backing up into properties. Once the liner is completely installed, the contractor will cut the liner where the sewer services are located, thereby reestablishing flow from each property to the public sewer.
