About the Program

Trenton Water Works (TWW) is committed to providing its customers with a safe, clean and reliable supply of drinking water. The risks and health effects of lead exposure are well documented, particularly to infants, young children, pregnant women as well as others with serious health conditions or compromised immune systems. Like many other aging cities and water systems, the TWW water distribution system is comprised of older houses and buildings, many of which have lead service lines (LSLs). As water travels through the LSLs, the corrosion of the lines adds lead into the treated water delivered to those customers. The treated water is otherwise lead free from TWW’s source reservoirs and treatment plant, and therefore these existing LSLs and lead solder in copper plumbing are the causes of lead in drinking water delivered to customers.

Due to the June 2018 lead action level exceedances, TWW is required to annually replace 7 % of the identified lead services lines in the system until the lead action level is no longer exceeded (currently a total of 14%). Rather than replacing only the TWW-owned portion of the service line, TWW is applying for State funding through the New Jersey Water Bank to assist the property-owner in reducing the cost to also replace the portion owned by the property-owner. The program is entirely voluntary; however, it is not anticipated that the cost to replace the property-owner’s portion of a lead service line will ever be lower than what this program is currently offering. The program is anticipated to have a duration of two years and remove at least 2,600 lead service lines for a total project cost of approximately $13 million. 

TWW has updated their inventory of LSLs and determined that there are approximately 19,000 LSLs in the TWW service area. Trenton Water Works serves the City of Trenton, Hamilton Township, Hopewell Township, Lawrence Township and parts of Ewing Township. TWW owns the portion of the service line from the water main to the curb stop. The portion of the service line from the curb stop to the meter inside the home is owned by the resident. TWW plans to replace 2,600 LSLs in the next two years.
