The Wastewater Treatment Plan (WWTP) conducts pretreatment, primary treatment, secondary treatment, disinfection and sludge disposal. Treated effluent is discharged under a permit to the Elk River and sludge is transported to the disposal area at the transfer station.
The District’s WWTP contains the following operations and processes:
The current Wastewater Treatment Plant consists of the following elements:
The existing WWTP was originally built in the early 1960’s. There have been several modifications and upgrades over the years to improve the treatment process.
In 1992, Sparwood was one of the first communities in BC to implement an ultraviolet disinfection system for effluent in order to protect the natural environment from effects of chlorine which was the alternative treatment method.
Sparwood continued their proactive approach and installed full back-up power generation at the WWTP to enable the facility to operate during power outages.
A new centrifuge was installed in 2008 to improve sludge management. These few additions allowed the WWTP to better dewater waste sludge and to reduce the sludge hauled by approximately 90% while also improving the safety of the operation.
If growth in the community continues we will require a new WWTP as the capacity of the existing wastewater treatment plant is approximately 5,800 people. The 2011 Census recorded our population as 3,460 people.
While the exact location has not yet been determined, we are looking at an area that is south and downhill from the rest of town. This will eliminate issues associated with the plant being right in town and the intent is to eliminate the requirement for sewage lift stations.
