Your family's health and safety is our number one concern. To ensure that your water is clean and safe, we only purchase product from county run filling stations. Our high quality, stainless steel tanks are sanitized regularly to ensure that we not only meet, but exceed the high standards set by the province of Alberta.  Water samples are taken on a monthly basis and sent to a lab to make sure there are no contaminates in either the hoses or the tank. During transportation from the filling station to your home, all of our hoses are sealed to protect against contamination, but in case of accidental contact we carry sanitization kits on board.
