Lead pipes are a matter of contention, especially in older cities of the Midwest. While many cities have implemented programs to replace lead pipes in their own water systems, there is still reason for concern. The replacements in many cases don’t include the line from the home to the street. Traditionally, replacing those pipes has been the responsibility of the homeowner. An alternative approach is to treat the water at the treatment plant, either adjusting the pH to prevent corrosion, or adding chemicals to coat the inside of lead pipes and prevent the lead from escaping into the water system.
Madison might be the only U.S. city to have replaced all lead lines, including customer-owned services, while using no anti-corrosion chemicals in treatment. Within a time span of nearly 20 years, Madison has replaced approximately 8,000 utility-owned lead service lines, while plumbing contractors hired by customers replaced about 6,200 private service connections. Grants of $3.8 million were provided to property owners, using money generated by renting antenna space on the Utilities water towers. The project took 11 years to complete and cost the utility about $15.5 million. Madison replaced lines instead of adding chemicals to avoid introducing more phosphorus through wastewater discharges, thereby lessening the risk of clogged meters and lines.
