Ivory Island Lightstation - Septic System Replacement

DFO and CCG are proposing to install a new septic system at the Ivory Island Lightstation. Ivory Island Lightstation is a staffed site located on the east side of Milbanke Sound, in British Columbia.


Ivory Island's septic treatment system has reached the end of its serviceable life and is not up to the current regulatory sanitary code requirements according to the Provincial Sewerage System Standard Practice Manual.  The existing system is comprised of one concrete tank for the main residence and a fibreglass tank with concrete walls for the secondary residence. Each tank has a single outflow pipe and no dispersion field. The proposed replacement system will strive to be a single code compliant Type 3 septic treatment system in accordance with the Provincial Sewerage System Standard Practice Manual.  This will address the site's current health hazards with the current system and provide the proper environmental treatment to ensure the effluent is within regulatory water quality levels.


The scope of this project includes a replacement of the current system and will strive to implement a Type 3 septic treatment system. This includes two 900 gallon tank replacements, plumbing upgrades, pipe-routing, and the install of a dispersion field.


Machinery used for this work will include: a barge, helicopters, mini-excavators, and hand tools.


The proposed construction timeline is May to June and the project will take place for a duration of approximately 14 working days.
