Project Profiles

Senkulmen WWTP

Project: Commercial Development
Location: Osoyoos, British Columbia
Capacity: 500 m3/d (130,000 gpd)
Contract: Design-Supply-Install

Key Features: Modular and Expandable, Enhanced Nitrogen Reduction;Mixed Residential/ Commmerial/ Light Industrial Users; Architecturally Distinct, Solar Power

Phase 1 of this treatment plant serving the Osoyoos Indian Band’s Senkulmen Business Park was constructed in 2010. The plant was expanded in the second phase in 2014 to the current capacity of 500 m3/d (130,000 gpd).  Two additional future phases will enlarge the plant to its ultimate capacity of 1,100 m3/d (290,000 gpd).

The plant consists of a rotary drum influent screen, flow equalization, USBF® bioreactors, microfiltration for effluent polishing and UV disinfection. The facility also pre-thickens sludge prior to sending it to drying beds. The entire process is automatic and SCADA monitored/controlled, reducing operator’s direct on-site input requirements.

Apart from the modular expandability, the design objectives included flexibility and robustness to handle influent streams from a local winery as well as a federal correctional facility, incorporation of advanced features including solar power generation, and an architecturally distinct design allowing the plant to fit seamlessly within the native theme of this progressive development.

Operated by the Osoyoos Indian Band, the facility discharges Class A+ effluent to wetlands.
