Lower Mainland System Upgrades

Surrey to Coquitlam natural gas line upgrades

About this project

More than 700,000 of FortisBC’s natural gas customers rely on our Lower Mainland natural gas system to supply natural gas to their homes and businesses in the Lower Mainland, Squamish, Whistler, the Sunshine Coast and Vancouver Island.

We’re upgrading the section of gas line between Surrey and Coquitlam so we can increase its capacity, keep up with growing demand and continue the safe and reliable delivery of natural gas to our customers.

This project involves creating a backup line that will run alongside the existing natural gas lines, in the same utility corridor, in both communities. Construction began in Feburary 2017 and will continue until the end of the year.

Having a backup, or second, natural gas line means we’ll be prepared to continue to meet our customers’ natural gas needs, even as communities grow. We’ll also be able to do routine “in-line” inspections, using state-of-the art equipment, to ensure the line’s safety and reliability.

Traffic impacts

Surrey to Coquitlam map illustration

The Surrey to Coquitlam gas line essentially runs in a straight line, but the streets beside the gas line corridor don’t, so a number of road crossings are necessary during construction. 

We’re making every effort to minimize traffic impacts during construction by using trenchless—drilling under the road— construction wherever we can. Where traditional trench—open-cut—construction is necessary, some temporary lane closures will be required and traffic delays may occur.

We’ll post upcoming construction activity notifications here so you can plan your commute in advance.  For specific updates on construction activities in your area, some of which may impact traffic, refer to the Updates page. We encourage you to sign-up for our newsletter and follow us on Twitter @Fortisbc for regular updates.


  • We’re installing approximately 5 km of new 36-inch natural gas line between our Cape Horn (2300 block of Rogers Avenue) and Coquitlam (Spuraway Avenue, near Mariner Way) stations.


  • We’re installing approximately 5 km of new 36-inch natural gas line from our Nichol Station (9378-138a Street) to the south side of the Fraser River.
  • We’re also installing approximately 1.2 km of new 42-inch natural gas line between our Nichol and Roebuck stations (9081 - 132 Street).

Gas line construction methods

Open cut construction

The type of gas line construction most people are familiar with is open cut, also known as traditional trench construction, where an open trench is dug and the gas line is laid in the trench. Open cut construction is the most commonly used construction method because it’s far less expensive than other methods, and is the simplest way to install a gas line. However, whenever road crossings are involved, the preferred method is some form of trenchless construction.

Trenchless construction

To learn more about the different types of construction methods used in the upgrade project, watch the videos and refer to the infographic for a summary of the various stages. More detailed information is also available as part of the Open cut and trenchless construction page.

Safety first

Safety is our number one priority. We have rigorous plans in place to ensure the safety and security of the public, our natural gas system, the environment and our employees.

We have a comprehensive approach to safety, with regular inspections and maintenance. Our transmission and distribution pipeline system continues to have an excellent safety record, and we renew and upgrade our system in accordance with Canadian codes and standards.

Jobs and procurement opportunities

FortisBC wants to maximize the benefit of our projects in the community. Opportunities to create local jobs, opportunities for aboriginal communities and other local economic benefits always shape our approach to our projects.

Save-On-Foods parking lot construction: 2662 Austin Avenue (at Mariner Way)

Construction will occur evenings only, 7 p.m. to 9 a.m. in order to minimize disruption to Save-On-Foods and its customers. The work will be completed in two phases:

  • Night work begins on the north side of the parking lot starting at 7 p.m. on June 22, ending at 9 a.m. on June 29. The work area will be fenced while construction is underway, then backfilled and paved to ensure there are no uneven surfaces for pedestrians and customers.

Construction update in the 13800 – 13900 block of Fraser Highway, Surrey

The visitor and over flow parking lots at the Edge and Verve condos in Surrey will close to all vehicle traffic as of Wednesday, May 24, 2017 while natural gas line construction is underway. A temporary parking lot is  accessible from Fraser Highway. This lot is lit, fenced and staffed with security guards.

Workers will be on site from 7 a.m. to 5 p.m. Monday to Saturday, throughout the rest of May, June and July. Crews will be following City of Surrey bylaws regarding noise and dust, trying to minimize both as much as possible. Heavy equipment, including excavators, will be operating in close proximity to the condo complexes. Homes closest to the work zone may experience some vibration.

Our crews will work as quickly as possible to return the area back to its original state. Closure dates are subject to change.

Keeping you informed

We’re committed to keeping the public informed about the gas line replacement project every step of the way. For more than three years, we’ve been meeting with local landowners, businesses, Aboriginal communities and municipal government representatives in both Surrey and Coquitlam to answer questions and address feedback.

We’ll continue to communicate directly with municipalities, business owners and residents affected by the project and provide opportunities to share feedback and ask questions throughout construction.

Environmental management

We are committed to working in an ecologically sensitive manner and to the highest standards. Environmental consultants have been working with us at every stage of the project to help protect vegetation, fish and wildlife and their habitat. We’ve developed a comprehensive environmental management plan and qualified professionals are on site to monitor work during construction.

How the Surrey to Coquitlam Upgrade project is creating jobs and economic opportunities for BC

More than $28.3 million to date in committed local spending and significant benefits across the region.

Economic and employment benefits

socio-economic benefits


We estimate the overall capital cost of the project will be $171 million. To date, $28.3 million has been spent on this project with 120 local vendors and suppliers.

Vendors and suppliers from 12 local communities are working on the project including:

  • surveyors
  • borehole drillers
  • electrical consultants
  • traffic controllers
  • archaeological and environmental consultant

More than 6,000 hours of technical review and fieldwork was carried out on the project by local Aboriginal businesses in areas of archaeology, environment and vegetation management.

See how we're committed to hiring local businesses.

Investing in our local communities

We believe in supporting organizations that help build safe and caring communities within our service areas.

Partnerships within Surrey and Coquitlam

As part of the Lower Mainland System Upgrades, we continue to raise awareness of the projects and strengthen partnerships that exist within the communities. In 2016, we invested in our local communities and provided sponsorships, including a Surrey Board of Trade event and the Coquitlam 125 Celebration community events.
