Filtering more than dredged water from Victoria HarbourEsquimalt Harbour, Victoria, BC, Feb 2017
The historic Esquimalt, Victoria, BC harbour is being cleaned up. Dredged bottom silt brought up is high in heavy metals such as lead and cadmium, as well as the detritus of a hundred+ year old military and shipping base. BI Pure Water designed a prefilter/ultra/nano filtration system that worked well to remove up to 99% of the heavy metals from dredged water in order to meet the extremely stringent BC Marine Aquatic water quality standards. They are among the highest effluent treatment standards in the world.
Commissioning of the system was in fact shut down for a short period as dredging pulled up a four foot live artillery shell. Other objects such as cannon balls, human bones and historical artifacts are being examined and catalogued by archeologists. /p>

Pumping water up the Vernon HillVernon, BC, June 2017
City water will be piped to the first of two pumphouses at lower elevation then delivered to 622 meters to a new subdivision in Vernon with incredible views. BI Pure assisted KWL in the design of Grundfos pumps at 107 USGPM to deliver the water; in the second pumphouse the chlorine content is assessed and boosted as needed by a BI Pure Water chlorinator, before distribution to homes. Care is taken to preserve the quality of Vernon city water. BI Pure Water delayed the delivery of the pumphouses until late June as the municipality is managing extreme spring flooding issues.
