Lead Service Line Project

PROJECT UPDATE: April 26, 2019
Today, crews replaced the final lead service line in the City of Northwood!  That means all 322 lead service lines in Rossford and Northwood have been replaced!  While this news is good, we still have restoration and meter replacement work to do.

Roadwork and Landscaping: Recent rainfall has been a challenge for road and landscape crews.  Crews are expected to return next week to Northwood for concrete and yard repairs, this work is weather permitting.  Due to weather delays, asphalt work is in the process of being scheduled.

Meter Replacement: Most of the meter replacement work in Rossford is complete, crews still have to replace many meters in Northwood.  Please be on the lookout for door notices with more information on when this work will take place.  You may be asked to schedule an appointment and we ask that you follow up promptly to schedule a convenient service time.

Expansion Tanks:  You should have received a letter regarding expansion tanks.  If your residence requires meter pit installation, there will be a backflow device installed on the new meter.  This device
can result in increased pressure within your system. The Ohio Basic Building Code, Plumbing: Section 607, “HotWater Supply System, Sub Section” 607.3.2, states that: “Where a backflow prevention device, check valve or other device is installed on a water supply system, a device for controlling pressure shall be installed.”  You should contact a plumber to determine the needs for pressure relief in your plumbing. The District will provide an expansion tank upon request at no cost to you for installation by you or your plumber.

Here is a link with more information on expansion tanks.  

Restoration work will continue through the early summer.

District Lead/Copper Replacement Project

In December,  The District will start an $883,000 project to replace all 322 known lead service connections in The District.   Speer Bros., Inc. of Sandusky, Ohio,  will serve as the prime contractor for this project.

If you have any questions regarding lead service lines, please contact Matt Dennis, at 419-354-9090 EX 125, or mdennis@nwwsd.org.

Map of Lead Service Lines

In 2016, under Ohio law (HB 512), public water systems were required to ID and map areas known or likely to contain lead and copper service line.  The maps are used by Ohio EPA to ensure that the proper lead and copper sampling is done in areas of lead service lines.  Within The District, less than 1% of our customers have or are likely to have lead service lines primarily in Rossford and the Homecraft area of Northwood.

Where are we working?

The project is scheduled to start this November in Rossford.

Even though you may have lead pipes, your water is safe to drink.  The Northwestern Water & Sewer District (The District) and your water treatment provider, the City of Toledo, are taking the proper steps to ensure your water is not contaminated.

If you have a home or rental property identified on THE DISTRICT LEAD AND COPPER MAP, you have been notified by The District via mail.

Prior to work on your property, The District and/or contractor will place a door hanger at your residence and use our auto calling system.   If you have not done so, we ask you SIGN UP HERE for automated calls.  Please make your contact information is updated if you have signed up.

Reduce Your Exposure to Lead in Drinking Water at Home

If you know or suspect that you have lead service lines or plumbing, there are ways to reduce your exposure to lead in your drinking water:

  • Use only cold water for drinking, cooking and making baby formula. Boiling water does not remove lead from water.
  • Regularly clean your faucet’s screen (also known as an aerator).
  • Consider using a water filter certified to remove lead and know when it’s time to replace the filter.
  • Before drinking, flush your pipes by running your tap, taking a shower, doing laundry or a load of dishes.
  • Contact The District to learn more about sources of lead and removing lead service lines.
  • Learn more by reviewing EPA’s Lead in Drinking Water Infographic.


Lead enters drinking water through corrosion in lead pipes or plumbing materials. The source of lead in water could be old service lines that connect homes to the water main in the street.  These service lines are a joint responsibility.  The District owns the portion of the line from the water main to the curb, and homeowners are responsible for the portion from the curb to their home.

Additional sources of lead in water include:

  • Interior lead pipe
  • Interior galvanized pipe (especially if there was, or is a full or partial lead service line)
  • Interior copper pipe with lead soldered joints (installed prior to 1988)
  • Interior plumbing fixtures (purchased or installed prior to January 2014)

What is lead?

Lead is a toxic metal that was used for many years in products found in and around homes. The primary source of lead exposure for most children is lead-based paint in older homes. Lead in drinking water can add to that exposure.

Uses for lead?

Lead is sometimes used in household plumbing materials or in water service lines used to bring water from the main to the home. Lead was banned from plumbing materials used to provide water for human consumption in 1986. The Safe Drinking Water Act states that only “lead free” pipe, solder, or flux may be used in the installation or repair of plumbing materials.

Action Level for Treatment Technique = 0.015 milligrams per Liter (mg/L) or 0.015 parts per million (ppm)

Maximum Contaminant Level Goal MCLG = 0 mg/L or 0 ppm

Sources of Contamination

Corrosion of household plumbing systems; erosion of natural deposits.
