Possible health risks from chlorinated drinking water
Water treated with chlorine for the purposes of disinfection may have handled a bacterial contamination worry but the chlorinated drinking water may still involve other health risks. 
How to remove chlorine from drinking water
Traditional methods to remove excess chlorine from drinking water use activated charcoal filtering. Because chlorine is volatile, you will also find that leaving water in an open pitcher or container will result in the dissipation of chlorine from that water quantity.
Details about the effects of chlorine in septic systems, tanks, and drainfields are provided at CHLORINE IN SEPTIC WASTEWATER. Excerpts are below.
Using a chlorinator on well water: At homes where the water supply is not potable due to bacterial contamination, a common temporary solution is the installation of a chlorinator.
Often this consists of an injector which doses incoming water with chlorine, a holding tank to give the chlorine time to work, and a post-processing charcoal filter to remove the chlorine from the water. It's preferable to find and correct the source of contamination.
