Though it's located within the City of Trail, the city's wastewater treatment facility is operated by the Regional District of Kootenay Boundary (RDKB). It is located in the community of Waneta near the eastern edge of the city above the Columbia River. The plant treats wastewater from not only the City of Trail, but the nearby towns and communities of Rossland, Warfield, Oasis and Rivervale.
Reclaimed wastewater is returned to the Columbia River, while solids, after dewatering, are included in current composting programs.
An overview of the plant follows.
The Regional District of Kootenay Boundary (RDKB) owns the Columbia Pollution Control Center (CPCC), a primary level sewage treatment facility that provides regional wastewater treatment and disposal for approximately 14,000 people residing in the municipalities of Trail, Rossland and Warfield, as well as the two smaller adjacent communities of Oasis and Rivervale. Each of these areas retains the responsibility for wastewater collection at the local level. A plan of the CPCC collection system is illustrated on Figure 1-1.
The treatment plant consists of screening of the influent wastewater to remove trash and coarse solids, followed by gravity settling to remove grit, and primary sedimentation to separate crude solids from the raw wastewater. The treated water is then disinfected by
using chlorine gas and then discharged to the Columbia River via an outfall. Waste solids from the primary clarifiers are stabilized in two anaerobic digesters and then dewatered using a belt filter press, with disposal of the dewatered biosolids to landfill. Future improvements to upgrade the existing plant to secondary treatment or to construct new facilities in an alternate location are currently being considered in the RDKB Liquid Waste Management Plan (LWMP).
