The Water Service Line Inventory Project
The primary focus of this inventory is identifying lead service lines. Lead is a common metallic element found in the air, water, and soil. If your home was built prior to January 1, 1987, and your water service line hasn’t been replaced since, there’s a possibility it may contain lead. It’s crucial to replace lead water service lines as they could contribute to elevated levels of lead in your drinking water.
The EPA has introduced new guidance and regulations requiring every public water system to establish and maintain a water service line material inventory, with the mandate to make it public by October 2024. Part of Pennichuck’s mission is to be a premier water supplier in New Hampshire, providing reliable, high quality, and affordable water. One way we fulfill this mission is by ensuring compliance with regulations set forth by the EPA and NHDES.
The water service line inventory is an assessment of materials comprising our customers’ water service lines and our water mains. It is compiled by utilizing all the data we currently possess on the materials used for water mains and water service lines throughout the years. If we lack sufficient evidence to determine the material of your water service line pipe, it will be classified as unknown until we can accurately identify it. This inventory is publicly available on this page below through a user-friendly, interactive map. We will actively work on gathering information from customers whose water service lines are categorized as unknown. If you have any questions, concerns, or would like to speak to someone about your service line or this project, please call us at 800-553-5191.
What is a Water Service Line
Your water service line is the pipe that runs from Pennichuck’s water main in the road to the inside of your home or business. It forms the direct connection between Pennichuck and yourself, serving as a vital component of the system that ensures a continuous water supply for domestic and recreational use in your home or business. Pennichuck owns all the infrastructure, also known as water mains, from our facilities until your shut off valve located near your property line. We are responsible for ensuring these water mains comply with current regulations set by governing authorities. As a home or business owner, you own the portion we defined above as the water service line. Your ownership begins at your curb stop, located near your property line, and continues into your home.
Replacing Your Lead Water Service Line
If you do have a lead water service line, it is important to speak to your health practitioner about the short and long-term health effects of lead. Taking steps to replace your lead service line is vital to minimizing your risk of lead exposure.
Pennichuck’s Goal
Pennichuck is dedicated to ensuring that all our customers receive water that not only meets but exceeds regulations and safety standards set by the EPA and NHDES. Our ongoing goal is to guarantee that drinking water coming straight from our facilities and through our water mains is lead-free. We are actively working to ensure that none of our current water mains contain lead material. However, if you have a lead water service line, there’s a possibility that the water flowing through may dissolve tiny fragments from your lead water service line and end up in your drinking water.
Our next objective is to encourage the replacement of all lead service lines within our systems, aiming to safeguard the health and safety of our customers.
More information regarding the entire inventory plan and Pennichuck’s forward-looking work plan will be made public by October 2024.
