World Trenchless Day
September 24 · Level 6 · #1111 of 2238
World Trenchless Day celebrates the engineering that installs and repairs underground utilities without digging a continuous trench. These methods help cities renew pipes and cables while reducing disruption to roads, trees and the people living above the work.
How it is celebrated: industry groups and companies share projects, host technical sessions and demonstrate equipment. Engineers compare methods and explain what can be achieved beneath busy streets.
Some damaged pipes can be renewed from the inside. A flexible liner is inserted into the existing pipe and cured to form a strong new lining.
