A water delivery system includes a showerhead featuring two delivery points, at least one of which has an own on-off valve, and at least a supply tube carrying untreated water. The showerhead features two separate conduits connecting the two delivery points with a coupling at the base of the showerhead handle, the tube featuring inside at least one secondary supply pipe carrying treated water. A proximal end of the tube is coupled with a coupling of the showerhead and one distal end thereof is intended to disappear from the user's sight, the distal end featuring two distinct supply ends to be connected with a distribution system of untreated water and to a centralised distribution system of treated water, respectively.
