The Town's surface water supply is the Morris Lake reservoir located in Sparta Township. This has been Newton's water source since the early 1900s.

Water Department personnel:

• Operate and maintain the water system
• Perform quarterly water meter readings
• Inspect all fire hydrants semi-annually
• Monthly leak detection

Since the Filtration Plant come online in 2006, Newton has met the lead and copper limits as required by the New Jersey Department of Environmental Protection (NJDEP).
