Chlorine can be removed by letting the water air out. That is the simplest solution if in fact your water department only added chlorine.

However, if they actually added chloramine then you will need a chemical solution. Chloramine was designed specifically to prevent itself from dissipating into the air, thus letting the water be protected for longer periods even when left standing.
This however, has nasty side effects for aquariums and ponds (instant fish kill) and to some degree some plants.

Do confirm with your water department to see the actual chemicals that they added. Chloramine will not air out.
