The solution to the lead issue in drinking water would optimally be replacement of all lead piping.
However, there are certain issues:
- The ownernership of the lead piping is between the supplier and the property owner, leading to possible legal aspects.
- The replacement costs are very high. Approximately 8-10 billion sterling pounds to replace all lead piping in the UK
- The density of properties with lead piping can be up to 75% in many cities. The replacment program would create much disruption to road users and property owners
- When the lead in water is not visible, tasted, odorless, it is not perceived as a problem. Property owners are then reluctant to take expensive actions.
