The stated cost of lead pipe replacement is very low. US costs can be about $5,000 to $10,000 if trenching is needed. Phosphate addition at a mg/l or so at the water plant works very well passivating lead pipe as well as brass surfaces along with other stabilization techniques. The 2nd photo does not look like lead pipe. Diameter is much too large and wall thickness is too thin. In the US domestic services are about 1 inch. Do they also have internal lead piping in some old homes?
