How often is chlorine added and how often is it monitored?

The concentration is monitored on a continuous basis through an on line monitor and is sampled by the operator hourly, 24 hours per day. In addition, the concentration of chlorine in the water is monitored at 18 locations through the distribution system on a daily basis to ensure an adequate concentration is maintained to ensure a safe supply of water to the customers.
