Chicago has the most lead pipes in the nation

I wonder what the accuracy of the data is like. And what do you do about damaged pipes? I read that cities lose a lot of water to leaks. Doesn’t that also mean pollutants can get in? And it won’t matter if your pipe is lead or whatever else.

An aside: lead exposure is thought to lead to increase violence. I wonder if Chicago having the most lead pipes is also a contributing cause of their (reputed) crime problem.

You replace them by running new service lines using directional boring, falling back to trenching when directional boring is not an option. In the case of waste and sewer lines, you can run an epoxy coating internally (“relining”) versus replacement, which has cost savings ($100-$250/foot of pipe).

Broadly speaking, maintaining this infrastructure is expensive because the need for labor is unavoidable and it is labor intensive.

Directional what? When Chicago replaces pipes, they dig the street up, put in pipes, and lay down a new street. I’ve literally seen them do this, then one month later tear up the same street for a natural gas pipe project .

These Chicago pipes are end of life and need replaced. They have been working on it for at least 20 years.

This is true. For the private sector, it works pretty well. Road digging permits are posted on their webpage 6+ months in advance. If you see one on a section of street you planned to do work on, you are allowed to piggyback on the project and share the cost. If you don’t, you pay the entire cost. So there is huge incentive to coordinate. But city agencies? Not quite so incentivized.
