Wastewater Collection System Rehabilitation

The project involves the rehabilitation of public mainlines and public laterals, and reconnection of each homeowner’s private house service line to those rehabilitated public laterals or mainlines.  The project does not include work on privately owned house service lines, except for reconnection to the public lines.

Bids for the rehabilitation work were received in January 2018.  Construction is expected to begin spring 2018, and take about three months to complete.  Additional notifications will be provided to property owners and residents about one to two weeks prior to the beginning of construction work within each respective area.  Construction is expected to take about one or two weeks for each area of work.

Allowable construction hours are Monday to Friday, 7 a.m. – 6 p.m. and 8 a.m. – 6 p.m. Saturdays. Construction is not allowed on Sundays or holidays.  There will be temporary road lane closures during construction; traffic will be controlled with appropriate signage and/or flaggers.  When needed, emergency access will be accommodated to any property, even during working hours.  Roadways will be opened at night and other non-working hours.

Project Background / Summary:

July 9, 2018 - Contractor's Construction Schedule

Below is a tentative schedule subject to change based on unforseen site conditions. 

Street/Alley Dates
The Alley between 2nd and 3rd Streets from D Ave. to E Ave July 12-30
South Shore Blvd. near the Fire Station   July 12-30
Within an easement between 455 and 475 Furnace St.     July 2-13

The duration of work within each area is anticipated to be 2 to 3 weeks.  Repair and rehabilitation work will be one of three different methods.  One method involves placing a Cured In Place Pipe (CIPP) liner within the old existing pipe.  Another method involves bursting the old pipe while inserting a new High Density Polyethylene (HDPE) pipe in its place.  The third method involves excavating a trench and laying new pipe parallel with the old pipe, then abandoning the old pipe in-place. 

March 22, 2018 - Inspections of sewer lines in April 2018

In early April, the contractor (James W. Fowler Company) expects to conduct closed circuit television inspection of all lines to be repaired and rehabilitated.

This work will not involve excavation, but placement of their television van and workers may require some traffic control signage or flagging. 

Once the initial inspection work is completed, the contractor expects to start the repair and rehabilitation work.  Their preliminary schedule indicates they will proceed as follows, however, schedules are subject to change:
