Due to COVID-19's impact on our personnel, TWW's Cortland Street office will close to the general public on Monday at noon until further notice. Customers can pay their water bills at City Hall (319 East State Street, Trenton) and online at www.trentonwaterworks.org. For billing inquiries and other business, please call customer service at 1-866-TWW-BLUE. Please delay your business with us for several days until our operations have normalized. Thank you for your patience and understanding.
