Sanitary Lateral Lining Program in Silver Springs

Water Services is conducting a pilot project in Silver Springs called the Sanitary Lateral Lining Program. This project will take place from April to November on select streets in the communities of Silver Springs. Please note that on the week August 10 – August 18, 2018, the streets that will be affected are Silver Hill Cres NW, Silverthorn Rd NW and Silver Hill Road NW
 
Program Summary
The Sanitary Lateral Lining Program is an innovative program that will install liners inside existing sanitary service pipes to extend the life of these assets. This trenchless process means that Water Services can rehabilitate these sanitary service lines without digging up streets and sidewalks.
The contractor for this program is LiquiForce who have 9 years’ experience performing this work in Canada. 
 
Why this program is necessary? Aging sewer infrastructure in older communities in Calgary is vulnerable to tree root intrusions, sewage backups, and costly repairs. The Sanitary Service Lining Program is a pilot to rehabilitate the existing pipe by using trenchless technology to install a liner. This method is less costly overall and less disruptive to the community rather than traditional dig and replace methods. 
 
Impacts on residents Liquiforce crews will give impacted residences project information and an estimated start date 2-3 weeks prior to installation beginning.  On the day of installation LiquiForce will notify residents in person 30 minutes prior to work starting. Homeowners and residence will be required to refrain from flushing their toilets, showers, bathtubs, washing machines and dishwashers for approximately two to three hours. That will help ensure that work can be completed efficiently, and reduces the risk of a sewer backup into the resident’s home. 
 
Residents may experience smells like plastic or glue coming into their homes. This will be a temporary issue and the smell should fade quickly. We are advising residents who have asthma or other respiratory issues of this scenario and asking them to take precautions during the work. 
We are asking residents to do two things before work begins in their neighbourhood:
 

1. Please pour about four liters of water into every floor drain, laundry tub, bath tub and shower drain in your home.  This may help eliminate fumes from entering your home. This can be done around 2 weeks after the homeowner or resident receives the estimated start date or the morning of if they are home when they receive their 30-minute notification of installation. 

2. If the homeowner or resident is home during the installation, they cannot flush toilets, use the shower, bathtubs, dishwashers and washing machines. Homeowners or residents could experience sewer backup in their homes if appliances are used during the installation window. 
Water Services in working with the Contractor will do our best to make sure sewer backups do not happen. In case they do happen, to limit The City’s liability, Water Services has worked with Law to incorporate the following statement in the literature, “Any resulting damage that occurs at or to the home form the homeowner or resident failing to follow the instructions in this Notice, will be at the sole cost and expense of the homeowner.” 
 
This information will be made available to residents through notices, 311 and online at calgary.ca/waterprojects. If you have any questions or concerns about this pilot program, please feel free to contact me.
