UPDATED DOCUMENTS 12/8/21

Each year, the Township of Parsippany-Troy Hills (PTH) Water Department is pleased to present its annual Consumer Confidence Report. The link to this report is on this page in the right column. The purpose of this report is to provide the water consumers of the Township of Parsippany-Troy Hills with a greater understanding of the quality of our drinking water and the system that delivers the water from the source to the user.

Responsibilities

The water utility operates, controls and maintains the Township’s water supply and distribution system, wells, well fields and all equipment and accessories for the treatment, distribution, conservation and protection of the Township water supply and water services.

The division is also responsible for the reading of meters, as well as the maintenance and services of all fire hydrants in the Township.

Water Source

The Parsippany - Troy Hills Water System is a groundwater- based system. Groundwater (or well water) is stored below the surface of the earth in large gravel deposits or deep porous rocks called aquifers. Groundwater is purified naturally as it filters through layers of soil, clay, rock and sand. This process known as “percolation” takes years to complete. As a result, Parsippany’s drinking water requires less treatment than surface water.

Water Quality

To ensure that the water serving our community is of the highest quality, Parsippany’s Water Department monitors and tests for physical, chemical, and bacterial contaminants in the water. The Water Department is not content with simply providing water to all of its residents and businesses. The Water Department is constantly improving the system to enhance the water quality, reinforce the supply of water and upgrade the distribution of water throughout the system.

Important Information to Know About Parsippany's Water System

Posted Tuesday, January 27, 2026
The Township’s water distribution system is made up of an interconnected network of pipes that include large transmission mains that feed smaller distribution mains and service lines. A series of valves throughout the Township’s system controls flow while pressure is maintained from the water stored in tanks and towers. Water pumping stations operate continuously to move water throughout the Township’s various pressure gradients. With so much complexity and so many pipes working to serve our communities, water main breaks can happen anywhere and at any time.
 
Why do water mains break?  Water main breaks happen for a number of different reasons:
 
  • Pipe age and material – Cast iron can be brittle and does not expand and contract easily with temperature changes.
  • Pressure changes – The pressure inside a water main can change. One of the most commons ways is through temperature changes or thermal expansion. Pressure changes can also occur when fire hydrants are either opened or closed too quickly causing a water hammer.
  • Ground settling – Over time, as the soil around a water main settles it can stress the pipe and break.
  • Corrosive soils – Some soils are corrosive and can eat away at pipes over time. This is especially common in iron and other metal pipes. Eventually the corrosion causes the pipe to break.
Water main breaks are significantly more prevalent in the winter often increasing by 50% or more, primarily due to freezing temperatures which causes soil to shift and frost to penetrate deep into the ground. This frozen, moving soil puts immense pressure on pipes, while colder water causes metal pipes to contract, become brittle and crack.
 
Key factors behind increased winter breaks:
  • Frozen ground and pressure
  • Thermal contraction
  • Freeze-thaw cycles
  • Colder water temperature
Rest assured that the Township of Parsippany-Troy Hills Water Department is well-equipped to respond to emergencies 24/7/365. To report a leak or if you believe you are being affected by a water main break and have any questions please contact the Water Department at 973-263-7099. The Township will continue to post updates on social media.

Mayor Pulkit Desai is sharing important tips from our Water Dept to help you avoid the headache of frozen pipes during this extreme cold.
 
Take a moment to open your sink cabinets and let your faucets drip. If the worst happens and a pipe freezes, remember to shut off the main water valve before you start thawing!
