Drinking Water & Legionella
Potable water testing, Legionella risk assessment and water management plans for buildings, cooling towers and new construction.
Drinking Water & Legionella in Ottawa and across Ontario
Building water systems can harbour Legionella bacteria and can pick up lead and other metals from old plumbing. We sample potable water and cooling systems, assess the risk, and help owners set up a water management program in line with ASHRAE Standard 188. For new buildings and long vacancies, we sample before occupancy to confirm the water is safe to use.

Drinking Water & Legionella questions
How often should we test for Legionella?
It depends on your systems and your water management plan. Cooling towers and high-risk buildings are tested more often. We help you set a schedule that matches your actual risk.
