Lead piping is another issue entirely. The water companies will replace lead pipes as they find them, up to the customers external stop tap as that is their limit of ownership. They have no powers to compel the home owners to replumb their houses, so instead they have to add ~1mg/l phosphate to the drinking water to control the solubility of the lead.
The crazy part is that the sewage works are being compelled to spend fortunes to upgrade the processes to remove phosphate (which comes from detergents and other sources as well as the drinking water dose) to reach environmental standards and prevent eutrophication. A little joined up thinking and long term investment in the lead removal rather than a simple to install dosing rig might reduce some of the pressures at the sewage works.
