PURPOSE: A chlorine injector and an injection method for a small water supply system are provided, which are characterized in that calcium chloride(CaCl2) is injected to the small water supply system only when water is supplied to the system, so that residual chlorine maintains an optimum condition constantly. The chlorination system controls chlorine dosage according to the variation of water usage. CONSTITUTION: Chlorination by this chlorine injector and an injection method for a small water supply system are characterized by comprising the following steps of: (i) starting of inflow and rising of water-level of a storage tank(3); (ii) operating a submerged pump(2) in a pipe-well(1) by sensing of water-level indicator in the storage tank(3); (iii) injection of water in the pipe-well(1) into the chlorine injector(7) through a bypass line(4); (iv) addition of calcium chloride into the injected water and mixing; and (v) input of the mixed water to the tank(3) through a main line(5). If the water supply is stopped and the submerged pump(2) operation is stopped, chlorine is not injected and a mixture of calcium chloride and water is not supplied.
