Petawawa's water treatment facility was upgraded to a state of the art, fully automated plant in 1993.  Thanks to the forward thinking Council of the day, residents of the community have the benefit of utilizing water that complies with and surpasses the highest drinking water standards in the industry. The process consists of flocculation, sedimentation, clarification, and filtration, and finally, chlorination.  All of these modern day processes are in place to ensure the highest quality drinking water.


Located on the southern shore of the Ottawa River and surrounded by Garrison Petawawa, the facility is rated at 21,500 cubic metres/day and at present day, is running at less than half of its rated capacity.  All aspects of the treatment process are continually monitored and alarmed, 24 hours per day, seven days per week.  Routine samples are collected and analyzed for microbiological, chemical, volatile organics, inorganics and pesticides on a daily, weekly, monthly and yearly basis.
