Separating stormwater from wastewater is better because it:
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.
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:
We have a separated sewer system in the following areas:
By 2020, we plan to install separated sewers in:
If you are a property owner in these areas, you will be notified when we begin to replace the sewer system in your area. You should plan to upgrade the sewer connection on your property at that time, at your own expense.
The City of Vancouver performs yearly sewer maintenance and sewer replacement, find out what to expect from construction in your area.
When the City of Vancouver installs separated sewers in your area, renew your home's sewer connection to be a part of it.
Find out the process for booking City of Vancouver inspectors to ensure that your sewer connection meets the current standards.
