What Are Underground Services and Why Are They Important?

Underground services, also known as underground infrastructure, refers to all buried utilities, including cables, pipes, and equipment associated with water, sewerage, telecommunication, gas and electricity. Pipelines that transport petrochemicals, bridges, and foundations buried under the ground also fall under underground infrastructure. 

But imagine having pipes, cables, and other utility lines running above ground; on roads, pathways, and every other place - modern life would be disturbed significantly!

These underground assets are important as they supply homes, businesses, and public buildings with hot water, gas, and electricity and eliminate wastewater. Even though we can't see these services, they need to be detected before excavation so they can be safeguarded.
