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:
 

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:
