Sewer Laterals Pilot Project Notice of Construction

Project Notice

York Region, in partnership with The Town of Aurora and The City of Vaughan, is implementing a pilot project for the inspection and repair of sewer laterals (the underground pipe connecting a residence’s sanitary pipe to the City’s sewer line). A contractor hired by York Region will be working in your neighbourhood to replace or repair deficient sewer laterals.

In May 2014, a closed-circuit television (CCTV) survey was conducted. An assessment of the sewer laterals was completed based on the CCTV data and those requiring replacement or repair were identified.

Construction will begin May 2015. The sewer laterals from the mainline to the property line will either be repaired or replaced based on the condition of the pipe. Work may include open cut replacement or trenchless cured-in-place-pipe repair.

During construction, residents are asked to limit their use of showers, baths, dishwashers and washing machines. A notice, with specific instructions based on the work required, will be provided 24 hours prior to rehabilitation work taking place.

Work will be completed on the following streets:


The Town of Aurora

  • Allaura Boulevard
  • Beckzy Street
  • Connaught Ave
  • Cousins Drive
  • Dunning Avenue
  • Edward Street
  • Gurnett Street
  • Harrison Avenue
  • Iber Court
  • Metcalfe Street
  • Royal Road
  • Temperance St
  • Tyler Street
  • Victoria Street
  • Wells Street
  • Wenderly Drive
  • Yonge Street

Frequently Asked Questions

 

What is the purpose of the Sewer Laterals Pilot Project?

The purpose of the Sewer Laterals Pilot Project is to reduce the amount of inflow and infiltration entering the sewer system through defective sewer laterals connections.

What is a “sewer lateral?"

A sewer lateral is the underground pipe connecting a residence or business to the sewer system, typically located in the street in front of your property. 

Leaking or broken sewer laterals are more common on older properties.  It is the property owner’s responsibility to keep the laterals on their property in proper working order. 

What are the benefits of the project?

  • Avoid sewer backups and costly maintenance due to tree roots growing into pipes or broken sewer lines
  • Increase the efficiency of our sewer system and contribute to reducing the overall cost of managing our system
  • Reduce possible environmental and safety hazards associated with sewage backups and overwhelming existing sewage treatment plants
  • Reducing the amount of clean water in our sanitary sewage sewer system helps increase the capacity of the system, leaving more for existing residents and helping to accommodate future growth

What is the timeline for the inspection and repairs?

We anticipate sewer connection repairs to take place in 2015.

What is the cost of the repairs?

There is no cost to participate in the Sewer Laterals Pilot Project at this time.  The Regional Municipality of York funds the project.

Do I need to be home during the inspection and repairs?

No, it is not necessary for you to be home during the inspection or repairs because our team will access the sewer connections underground from the main sewer line located on public property. If you do plan to be home or working during the inspection or repairs, our team will ask you to reduce your use of water including taps, washing machines, and dishwashers during the inspection period.  We will inform you of the inspection schedule and provide you with a notice 24 to 48 hours in advance of inspections occurring.   

Do you anticipate any impact on property owners during inspection or repair work?

During inspections, you can expect to see a truck and trailer parked in front of manholes on your street. Inspections of the laterals will take place one-at-a-time along an entire street.

The contractor will complete the inspection using a closed circuit television (CCTV) to survey the sewer lateral up to the property line and connection to the municipality’s sewer mainline. The camera is non-intrusive and will not result in impacts to local property owners. 

Minor, localized traffic disruptions may occur, however, traffic control measures to minimize any impacts on local residents. 

If you have a manhole located at the end of your driveway, you may experience temporary blockage of your driveway.  Prior to inspection or repair, the contractor will notify you if a temporary blockage will occur.

To avoid inconveniencing property owners, inspections or repairs will not start before 7 a.m. and will finish before 7 p.m., from Monday to Friday.

Could future repairs cause sewage back-ups or smells?

The inspection and repair methods used will not cause sewage backups. Rather, they aim to help prevent sewer backups from occurring.

Will the repairs damage my trees, shrubs, garden or lawn?

Impacts to existing landscaping are not anticipated. Many sewer laterals will not be in need of repair or will require a simple trenchless repair which does not require digging.

How will York Region inform me of inspection and repair impact or road closures?  

We will inform property owners within the community about any activity in advance, so you are aware of our work and any potential impacts that may occur. 

Information about the project will be provided through the following channels:

  • York.ca
  • Door hangers distributed to homes in priority areas
  • Toll-free hotline 1-877-464-9675 gives you the opportunity to discuss the project with a member of our team
  • Project email: sewerlaterals@york.ca

How will you manage noise impact during the inspection and repair process?

The inspection and repair process does not require the use of heavy equipment and therefore very little noise will be generated.

What is York Region doing to ensure safe inspection and repairs?

Health and safety is paramount to how we work at York Region. Appropriate notice, signage, and other health and Safety and traffic precautions will be in place at all times when sewer inspections or repairs are taking place.

What are the steps property owners can take to reduce sewer lateral problems?

The simple answer - do not put anything down the drain or toilet that could cause problems. This includes fats, oils and grease, medications, wipes and hazardous liquids. Fats, oils and grease clog sewer lines. Medications and hazardous liquids pose challenges for the sewage treatment process and can corrode pipe material.

What is Inflow and Infiltration? 

Inflow and Infiltration (I&I) can occur when surface and/or groundwater enters the sanitary sewage system and adds clean water flow to the sanitary sewage flows. Typical defects in sewer laterals that can cause inflow and infiltration are root intrusions, leaky connections or broken pipes, as shown in Figure 3.
