Trenton Water Works Issues Water Conservation Advisory

News & Announcements Posted on December 18, 2025

Trenton, NJ — Trenton Water Works (TWW) today issued a Water Conservation Advisory, asking customers and residents in its five-municipality service area to conserve water voluntarily until further notice. TWW provides drinking water to more than 200,000 residents.

 

TWW mailed the Water Conservation Advisory to all of its customers, and it is also available online under News and Announcements at trentonnj.org/154/Water-Sewer.

 

"Cold weather impacts the performance of our water infrastructure, and we are ready to address any operational issues," said Sean Semple, Director of the city's Department of Water and Sewer, which operates Trenton Water Works. "Although there is no disruption to treatment or distribution, freezing temperatures and prolonged cold weather conditions affect TWW's water filtration plant's ability to pump water from the supercooled Delaware River and water mains and service lines in our 683-mile distribution system."

 

During these seasonal operational challenges, TWW is encouraging customers and service-area residents in Trenton, Hamilton Township, Ewing Township, Lawrence Township, and Hopewell Township to prioritize essential water use for drinking and cooking, sanitation and personal hygiene, and fire suppression and emergency needs.

 

Non-essential water use includes washing vehicles, watering lawns and landscaping, filling pools or operating decorative fountains, and running dishwashers or washing machines with partial loads.

 

"TWW's water filtration plant on Route 29 South in Trenton continues to operate normally and is capable of meeting drinking water demand," added Semple. "The Water Conservation Advisory helps ensure system reliability and performance during extreme cold temperatures."

 

To report water main breaks, toppled-over fire hydrants, service line leaks, and other water emergencies, customers and residents can call TWW's 24/7 hotline at (609) 989-3222.
