Is there a long term plan for sewers in Colwood?

See the map of existing sewer lines in Colwood (updated November 2016).

Colwood's Sewer Master Plan shows how sewers could be built throughout Colwood, but the major funding required is not available at this time. As new developments are built in Colwood, there will be more opportunities for property owners to connect.


Septic Systems

The majority of Colwood households (about 70% of the current population) are on septic systems. When properly maintained and situated, septic systems are an environmentally friendly and economical option. Properties with septic systems pay the Capital Regional District Onsite Sewage Parcel Tax which allows the CRD to monitor for safety of septic systems. Read more about Septic Systems in the CRD.

Municipal Sewer Service

Just 30% of existing Colwood households are currently hooked up to sewer service. These property owners pay a sewer user fee to help keep the almost 40,000 m of pipes and infrastructure. including 8 lift stations in safe working order. The City’s system also services commercial properties including, Royal Roads University, DND lands, two golf courses, schools, and the Juan de Fuca Recreation Centre. 

Connecting to Sewers in Colwood

Many properties in Colwood do not have sewer lines nearby, which is why the majority of homes are on septic service. For these property owners, connecting to sewers is currently only possible by petitioning neighbours to assess interest in paying for pipe extensions by establishing a Local Area Service

Properties that are adjacent to existing sewer lines may choose to connect. The typical cost to have the City connect the sewer line to a property is approximately $9100. There is an additional cost of between $3000 - $5000 to bring the line to the home and decommission the septic system.

Read the Sewer Backgrounder page to learn more about the history of sewers in Colwood, how to connect and future plans for sewers in Colwood.

Central Sewer Extension 2016

In 2016, the City will undertake the expansion of the Central Sewer Local Area Service along a designated area between Hatley Park Mall on Sooke Road and a section of Metchosin Road. Property owners adjacent to the extended sewer will have the opportunity to connect to sewer service. Get all the details on the Central Sewer Extension.

Regional Sewage Treatment Plans

Determining the best long term sewage treatment solution for the City is one of Colwood's key strategic priorities.

The previous CRD plan from 2008 called for a $788 million sewage treatment facility (which would cost in the range of a $1billion in today's dollars) at McLoughlin Point that seven municipalities in the region were expected to contribute to. That plan envisioned an additional facility on the Westshore when McLoughlin Point reached capacity in about 2030. That option was rejected when the property could not be rezoned for a wastewater treatment facility.

The majority of residents in other municipalities are already connected to sewers, so the cost of treatment is distributed to users of the sewer system. But with only about 30% of Colwood homes currently connected to sewers, this plan means most Colwood residents would be paying for a service they will never use and then paying again when the Westshore plant is required.

Colwood's Plan for Local Sewage Treatment

In February 2014, Colwood received CRD support for an amendment to the Core Area Liquid Waste Management Plan to allow for the development of a small-scale treatment facility with resource recovery opportunities in Colwood.

Colwood represents a very small part of the regional sewage treatment plant (only 4.7%). Our plans would not have a negative impact on the CRD plans, and was estimated at the time to save taxpayers in core area municipalities about $245 per year in future taxes by relieving them of the cost of building the future plant.

A facility like this would provide water for nearby recreational facilities and draw heat energy from sewage pipes that could be distributed to businesses in the heart of Colwood and neighbouring facilities like West Shore Parks and Recreation and Royal Roads University. Check out "How district energy works" from Fortis BC.

Going to a local system that could start small and grow with our community, as well as being able to reclaim heat and water, would substantially reduce the tax burden on our community and our impact on the natural environment. It would also free up space for other municipalities in the larger CRD sewage treatment plant, extending the life of that facility.

What would a sewage treatment facility in Colwood look like?

On the surface, it would look like a simple residential and commercial building. The underground treatment operations would be virtually invisible and completely odourless. There would be no ocean outfall. Plus, the facility would provide energy to connected buildings as well as clean treated water for things like local irrigation.

[An important correction: A recent article in the Times Colonist incorrectly stated that the City of Colwood had spent $700,000 on a 'sewage treatment pilot project'. In fact, it was a company called Ledcor who spent $700,000 in our community to conduct a very successful pilot of their equipment, which is now in use in Arizona.]
