Say Goodbye to Contaminated Water: The Importance of Replacing Lead Water Service Lines


Table of Contents

Lead contamination through drinking water is a major health hazard. Many older homes still have a lead water distribution system connected to the municipal water infrastructure. These aging lead service pipelines can leach lead into tap water. Replacing lead pipes is essential to get rid of lead in your drinking water and protect families from lead poisoning. This article explains why the full exchange of antiquated lead conveyance tubes should be a top priority for homeowners and communities.

Lead Exposure from Drinking Water

Lead water pipes, known as service lines, were commonly installed in homes built before the mid-1980s. Over time, lead from these old pipes can dissolve into the water flowing through them, contaminating drinking water. Lead solder and plumbing fixtures may also leach lead into the water. Corrosive water can further dissolve pipes made from lead and cause higher lead levels at the tap. Even new brass fixtures may contain traces of lead. There is no safe level of lead contamination.

The Health Effects of Lead

Lead builds up in the body over years of repeated exposure. Even small amounts can be harmful, especially for children and pregnant women. Lead affects brain development in kids, impairing cognition and causing behavior disorders, learning difficulties, and other long-term neurological problems. Adults also face increased risk of heart disease, kidney damage, reproductive issues, and other serious health impacts with continued lead intake.

Checking for Lead Pipes in Your Home

Contact your municipal public works department to learn if your home’s service pipes contain lead. They should have records of the materials used. You can also hire a plumber to visually inspect the pipe where it enters your house. Lead has a dull gray color and is easily scratched. If your home was built before the mid-1950s, it likely has pipes made of lead.

Why Full Replacement of the Lead  Water Lines is Necessary

Partial substitution or chemical treatment cannot reliably reduce lead levels. Over time, lead will recontaminate drinking water from any remaining lead solder, pipes, or the scale within aged conduits made of this toxic metal. The only permanent solution is the full removal and replacement of all lead plumbing components. This prevents lead contamination at the tap and protects your family’s health for the long term.

Roles and Responsibilities in Replacing Lead Service on the Private and Owned by the City Property

Complete substitution involves removing the entire existing old lead pipe and installing a newer pipe from newer materials such as copper or plastic in its place. The municipality owns the portion from the water main to your property line and covers substitution costs for this public section. Homeowners are financially responsible for replacing the private owned portion from property line to house. Coordinated replacement is ideal.

In Toronto, a focused initiative is underway to substitute lead pipes owing to the health hazards linked with lead contamination, especially for susceptible populations such as expectant mothers and young children. The city has initiated programs and policies aimed at facilitating the removal and substitution of aging lead pipes, both on public and private properties. The exchange of these pipes is critical to ensuring that residents have access to clean and safe drinking water, free from the hazards of lead contamination. The city encourages homeowners to participate in lead pipe replacement initiatives, offering support, guidance, and, in some cases, financial assistance or subsidies to expedite the process. Through collaborations between the municipal government, homeowners, and skilled contractors, Toronto continues to make strides in safeguarding public health by minimizing the community’s exposure to lead through the city’s network for distributing water.

 The Lead Service Line Replacement Process

  1. Evaluation: The city inspects the public part of your line for lead and schedules the entire replacement if needed.
  2. Installation: Crews replace both the public and private lead pipe sections with new copper or plastic.
  3. Reconnection: Your building’s plumbing is reconnected to the new service pipes. Pipes are flushed to remove lead particles.
  4. Testing: Water samples are analyzed to confirm the amount of lead tested below the 5 ppb standard after substitution.

Assistance Options to Replace Private Lines

Some programs provide grants or low-interest loans, assisting homeowners in funding the replacement of the portion of the conduit they possess. Contact your municipality to ask about any financial assistance available for lead line substitution in your community. Replacing aging pipes now also prevents more costly emergency repairs later.

For example, the city of Toronto offers a program to fully substitute lead water line pipes on private property at no cost to homeowners. Over 3,000 lead pipes have been replaced through this program since 2005.

Timeline for the Replacement Project

For a single-family residence, substituting the entire lead conduit usually requires 1-2 days total. On the second day, the public side typically receives an upgrade before the private line portion. Your water service will be temporarily disconnected while the installation of the new one is being done. Minimal restoration is needed where pipes are excavated.

Lead Reduction Before Replacement

Only use cold tap water for drinking or cooking until you replace the lead line. Hot water can dissolve lead. Water does not remove lead, but flushing pipes by running water for 3-5 minutes can help reduce the presence of lead before use. Consider installing a water purifier certified to remove lead or using a filtered water pitcher. Avoid cooking with or mixing baby formula with hot tap water. Check with your water provider about other precautions.

Make a Priority Lead Water Service Replacement

The complete removal of lead pipelines needs to become an urgent public health priority. Too many communities still have high lead contamination risks. Upgrading aging water infrastructure takes substantial funding and a long-term commitment. Through partnerships between residents, health agencies, and municipal leaders, we can drive real progress on removing lead from drinking water for future generations. There is no safe lead concentration in service line material; replacing these pipes protects kids.

In summary, total substitution is the best permanent solution if your home has a lead pipe. Contact local officials about your water distribution system, get on replacement schedules, learn about financial help available, and take interim precautions. Removing lead sources from public water supplies will have long-lasting health benefits for entire communities.

 How does the Program for Lead Water Service Replacement work?

The program aims to replace the water service pipes with lead, prioritizing areas with a higher risk of lead contamination.

 Who is responsible for the exchange of the lead-based pipes?

The water distribution system from the lead is the responsibility of the property owners, but the city of Toronto is providing assistance through the program to replace the lead pipes.

How can I get my water tested for lead?

Contact the city staff or Health Canada to arrange lead testing for your water.

What should I do if my water tests positive for lead?
