SERVICES INTERNALLY REINSTATED
This project was apart of the City’s yearly watermain rehabilitation program to address it’s aging and failing watermains. This contract included both cast iron and ductile watermains including a large amount that contained insitu-lined cement mortar that required removal.
The majority of this project was located residential neighbourhoods with a small amount of work located in commercial areas. The residential neighbourhoods that were included within varied in density stretching from Pleasant Ave, Glendora Ave, Glen Long Ave and Forest Heights Blvd among many others. Several of these neighourhoods included schools which required additional coordination with the City as well as the schools themselves. The commercial locations of this project included Alness Ave as well as a section of The East Mall and Bloor St. The residential neighbourhoods included within this contract contained mature tree lined streets where a large amount of water service replacements were required. Through coordination with the City, their consultant and the City’s forestry department, FER-PAL was able to avoid damaging or the removal of well over 50-trees. This is in addition to the trees that would have been removed should CIPP Lining not have been chosen as the method of construction.
One of the largest challenges within this contract was that over 42% (3,521m) of the watermains required the removal of cement mortar lining prior to the installation of CIPP lining. Ensuring a quality product was installed meant that the cement lining required full removal. FER-PAL was able to successfully remove all of the cement mortar coating. This success of this removal was evident as the project was completed with a defect ratio of .14%.
