Sewer Separation Mandate in Vancouver

As they work toward the Province of BC's goal of eliminating sewage overflows, the City of Vancouver is replacing older, combined sewer systems with a new separated sewer system. This means all properties within the City of Vancouver will eventually need to have separated sewer systems that originate at the building, extending to the city’s main sewer.

The upgrading of older, inadequate drainage systems is now mandatory within the City of Vancouver and is the responsibility of the homeowner to pay for any upgrades deemed necessary.

If you are a Vancouver property owner you are responsible for maintaining the sewer lines on your property – up to where they meet the City's sewer connection.

1. The overall sewer mains are being separated so that storm drains carry storm water runoff separately from other waste water.
2. Similar work is being done to separate the sewer mains that serve private properties.

In a combined sewer system, storm water runoff is combined in a single sewer pipe with waste water from homes, businesses, and industry.

During dry weather, both types of runoff go to the sewage treatment plant together without problems. However, during periods of heavy rain, the high volume of storm water can exceed the capacity of a combined sewer system, resulting in untreated waste overflowing and emptying directly into our waterways, flooding our streets and occasionally backing up into basements.

In a two-pipe, separated sewer system, storm water is collected through storm drains and travels through different pipes than sewage and other waste water, resulting in the elimination of combined sewer overflow as well as preventing flooding. Rainwater collection begins with the perimeter drainage systems of all buildings, including private homes.

As sewer upgrades take place, it is necessary to look at all components of your home’s drainage system, including the foundation drain tile (also known as French drain, weeping tile or perimeter drain) and drainage pipes that connect to the City’s sewer mains. Perimeter drainage systems and sewer connection pipes that are damaged by roots or are corroding due to age will probably need to be replaced.

If your property currently has only one pipe connecting to the city’s sewer, that will have to be replaced with separate pipes – one for the sanitary waste from your home’s interior and the other for rainwater removal from your property to the storm sewer main.

In particular, older properties will undergo a complete drain system evaluation, including sump pump repair, perimeter drain replacement and sewer connection pipes.

We are working toward the Province of BC's environmental goal to eliminate sewage overflows by 2050. As we replace combined sewer systems with separated sewer systems, properties will also need to have separated sewer systems.

In a combined sewer system, stormwater runoff is combined in a single pipe with wastewater from homes, businesses, and industry.

During drier weather, the stormwater and wastewater are carried to the sewage treatment plant together. But in heavy rains, high volumes of stormwater can exceed the capacity of a combined sewer system. The excess, untreated amounts overflow and empty directly into our waterways.

How we Prioritize Sewer Replacement

In a two-pipe separated sewer system, stormwater is collected through storm drains. It travels through different pipes than household sewage and other wastewater.

There are two sewer separation programs running concurrently. The overall sewer mains are being separated so that storm drains carry stormwater runoff separately from other wastewater.

Similar work is being done to separate the sewer mains that serve private properties. This project focuses on smaller areas based on the following conditions:

• There is a documented history of sewer line blockages that we were fully or partially responsible for
• An indication that a managed sewer line maintenance program we implemented is no longer effective or has become exhaustive
• The property owner has fully replaced the private property portion of the sewer line and reports that our portion is in poor condition
