Effluent Outfall to Kootenay River

As part of the upgrades to Cranbrook's Waste Water System, an outfall is being built into the Kootenay River.  The City has stated that they don't anticipate using this outfall for another seven years.  It cannot be used until both ultra violet disinfection and alum treatment have been put in place.  The outfall is the end of the effluent pipe that will join to the City's new and third effluent storage pond on the Spray Irrigation Fields.   Divers will  hook up the diffusers once the pipe is in location under the bed of the Kootenay River.

The length of pipe shown in the photo will all be pulled across the river to the East side. At that point the horizontal drill will drill across the river, from west to east, staying just below the bed of the river. After the drill has reached the east side it will be hooked to the end of the length of pipe and will pull the pipe back through the tunnel that has been drilled. Once the end of the pipe with the welded openings are in the correct location under the river bed then the divers will be sent down to dig down through the river bed and attach the diffusers.
