(28)With the aim of minimising the potential presence of lead content in water intended for human consumption, components made of lead in domestic distribution systems can be substituted, in particular in the event of repair or reconstruction works in existing installations. These components should be substituted by materials which comply with the minimum requirements for materials that come into contact with water intended for human consumption, as established by this Directive. In order to accelerate that process, Member States should consider and, where relevant, take measures for the substitution of components made of lead in existing domestic distribution systems, if economically and technically feasible.
