Last verified: October 8, 2026, against the City of Topeka's Lead and Copper Rule Improvements Q&A (2025), its 2026 Water Quality Report and the City's service line inventory map. Program details change, so check with the City before you act.
In November 2024, and again in November 2025, the City of Topeka mailed brochures to the addresses its records list as having a lead service line, a galvanized line that requires replacement, or a line of unknown material. If one landed in your mailbox, this guide explains what it means, how to check the pipe yourself, and what to do next. If you did not get one, that is good news: according to the City, no mail means its records show your line is not lead, galvanized requiring replacement, or unknown. Blackburn Plumbing is led by a Licensed Master Plumber and has served Topeka homeowners since 2010. Questions? Call 785-260-0299.
In October 2024, City of Topeka Utilities published an inventory of the water service lines in its system, as required under the federal Lead and Copper Rule Improvements (LCRI). It counted 291 lead lines, 810 galvanized lines that require replacement, and 3,112 lines whose material is still unknown. Those counts cover both the City-owned side and the customer-owned side of each line, so a home can appear on the list even when the pipe under its own yard has never been looked at. The inventory and the program documents are linked from the City's water quality page, under "Topeka's LCRI Compliance."
A water service line is the underground pipe that carries water from the City's main to your house. Every line has two sides. The City's side runs from the main to the curb stop or meter, and the homeowner's side runs from there to the spot where the pipe comes into your home, usually just before the main shutoff valve. The inventory records the material of both sides, and either one can be lead or galvanized steel. If you are not sure where the split falls at your address, ask City of Topeka Utilities.
The City's inventory map has been public since October 2024. To look up your home:
Unknown does not mean lead. It means the City needs information, and often the homeowner can supply it by looking at the pipe where it enters the house.
Find where the water line comes into your home, usually in the basement, a crawl space or a utility room, and look at the few inches of pipe just before the main shutoff valve. Then compare what you see:
Scratch lightly, and never file or cut into the pipe. Take a clear photo of the pipe and the scratch so you have it when you report it. If what you find does not match the City's record, the City's 2026 Water Quality Report says to contact the City. Keep in mind that this check only tells you about the pipe entering your home. It does not show the City's side under the street.
Lead service lines were banned under a 1986 federal rule that took effect in 1988, so a home built before 1988 may have one. The City's Q&A adds that lead was common from the early 1900s to the 1960s. That covers much of Topeka's older housing, including established neighborhoods like Highland Park, Oakland, College Hill and Potwin. The same era also left many homes with galvanized steel supply pipe inside the walls, which corrodes from the inside and restricts flow over time. Repiping older homes' supply lines with copper or PEX replaces lead and galvanized pipe inside the house.
Until your line is identified or replaced, the City recommends simple interim steps:
If you are adding filtration at home, our water filtration team can talk through the options. For drinking water, choose a filter certified to remove lead.
The federal Lead and Copper Rule Improvements take effect in 2027 and require lead service lines to be replaced by 2037 in most cases. Homeowners do not have to wait for the City's schedule. In its 2025 Q&A, the City says: "You can choose to contract with a private plumbing contractor to replace your service line. You should choose a plumber familiar with the City codes and permits necessary to do so."
On funding, the City says it "is actively exploring potential funding options" and that more information will be forthcoming. For questions about cost, funding, and which part of your line the City will replace, contact City of Topeka Utilities before you make plans.
If the pipe inside your home is lead or galvanized steel, our repiping service replaces it with copper or PEX, and a Licensed Master Plumber can look at the pipe where your line enters the house. Call 785-260-0299.
The City's 2026 Water Quality Report shows a 90th percentile lead level of 2.4 parts per billion, with results from 0 to 6.0, in its 2021 to 2023 sampling, and no homes above the federal action level. Your own service line and plumbing can still add lead, so if your line is lead or unknown, the City's interim steps still apply. For City water testing, call 785-368-0943.
According to the City, no mail means its records show your service line is not lead, galvanized requiring replacement, or unknown. If you believe the material listed for your property is wrong, contact the City.
Yes. The City's inventory tracks galvanized lines that require replacement as their own category, 810 of them in the October 2024 count, alongside 291 lead lines. Galvanized steel supply pipe inside a home also corrodes and restricts flow over time, which is a repiping job. Call Blackburn Plumbing at 785-260-0299.
A filter certified to remove lead is one of the City's interim steps for homes with a lead or unknown line, along with running the tap for 3 to 4 minutes after water has been sitting in the pipes. Check that the filter is certified for lead removal before you buy it.
Contact the City of Topeka. Its 2026 Water Quality Report asks homeowners who believe the service line material listed for their property is incorrect to contact the City. You can also report your line's material through the City's Survey Information tool, and the City's water testing line is 785-368-0943.
