#The Importance of Underground Utilities
Underground utilities are the unseen infrastructure that keeps our modern society running smoothly. From power lines to water pipes, **underground utilities** provide essential services that we often take for granted. In this post, we'll explore what's under our feet and why proper **underground utility** management is so crucial.
##What Are Underground Utilities?
**Underground utilities refer to any cables, pipes, wires, and related infrastructure that have been buried underground. Some examples of common underground utilities include:
- Electric power lines - These cables distribute electricity from power plants and substations to homes and businesses. They are usually buried a few feet underground.
- Natural gas pipelines - A network of pressurized pipelines transports natural gas from wellheads to consumers. Gas lines are buried about 3 feet deep.
- Water mains - Large diameter pipes distribute clean drinking water from treatment plants or wells to various properties. Water mains are typically 4-8 feet underground.
- Sewer lines - A system of large pipes collects wastewater and transports it to treatment facilities. Sewers are laid 6 feet or more below ground.
- Telecommunication lines - Fiber optic and copper cables provide telephone, cable TV, and internet connections across buried conduits. These are around 3-6 feet underground.
- Storm drains - Collects and diverts rainwater runoff through concrete pipes to prevent flooding. Storm drains range from 2-15 feet below ground.
Proper installation and management of these **underground utility** systems is imperative for public health, safety, and quality of life.
##The Benefits of Underground Utilities
There are a number of compelling reasons why most modern **underground utilities** are buried rather than being mounted on overhead poles and towers above ground:
- Aesthetics - Underground lines don't clutter the landscape with unsightly poles and wires stretching across neighborhoods. This helps preserve natural scenery.
- Safety - Buried power lines won't come crashing down during storms, minimizing electrocution and fire risks. Underground pipes reduce the chances of accidental gas line ruptures and explosions.
- Reliability - Underground infrastructure is protected from falling trees, lightning strikes, ice storms, high winds and other threats that can interrupt overhead service. Underground systems experience fewer outages.
- Property values - Homes and neighborhoods with buried utility lines have higher property values than areas blighted with overhead poles and wires. Underground lines also allow for larger trees that increase curb appeal.
- Security - It is more difficult to access and tamper with buried utility equipment compared to easily accessed overhead lines and components. Critical infrastructure remains secure underground.
##The Risks of Aging Underground Systems
While modern underground utility systems provide many benefits, much of the buried infrastructure in the United States is decades old and approaching the end of its useful life. Crumbling water mains, deteriorating natural gas lines, and fraying power cables pose a growing risk. As this critical infrastructure continues to age, it becomes more vulnerable to leaks, ruptures and failures.
Some of the main concerns with aging underground utilities include:
- Pipe corrosion and cracks - Decades of exposure to soil and groundwater causes pipes to corrode and eventually crack, resulting in costly leaks and equipment damage.
- Line breaks - Frequent line breaks release gases, discharge sewage, disrupt service and necessitate emergency repairs. For example, there are around 700 water main breaks per day in the U.S.
- Safety hazards - Escaping gases, downed live wires and other breakdowns create dangerous situations for workers and the public. Ruptured lines are the leading cause of sewer overflows.
- Power outages - Failing buried cables cause more frequent blackouts and brownouts as they deteriorate past their intended lifespan.
- Environmental harm - Leaking sewer lines spill raw sewage that pollutes groundwater and waterways. Millions of gallons are lost annually from deficient water infrastructure.
##The Importance of Rehabilitation and Replacement
To address the risks of aging **underground utilities**, municipalities and utility companies are ramping up rehabilitation and replacement programs before major failures occur. Some of the solutions include:
- Pipe relining - Trenchless pipe lining with epoxy resins can essentially create a "pipe within a pipe" to seal cracks and restore structural integrity in water and sewer lines.
- Main replacements - Wholesale replacement of deteriorated lines prevents leaks and improves flow. Priority is given to pipes based on leak history, size, age and material.
- Cable upgrades - Swapping out degraded low-voltage cables for new higher-capacity versions maintains power reliability.
- Maintenance holes - Rehabilitating brickwork, frames and covers on maintenance holes prevents groundwater infiltration that damages underground equipment.
- Shut-off valves - Replacing inoperable gas and water valves provides greater control over sections of utility lines during maintenance and emergencies.
- Leak detection - Regular inspection and leak detection allows utilities to pinpoint problems and prevent bigger failures down the road.
Investing in the rehabilitation and replacement of **underground utilities** will keep them functioning safely and efficiently for decades to come. Preventative maintenance is far cheaper than emergency repairs after a catastrophic failure. Prioritizing infrastructure upgrades will ensure quality service delivery as assets reach their lifespan limit.
The unseen network of **underground utilities** running beneath our feet makes modern life possible. As this infrastructure continues to age, properly maintaining and replacing underground systems will be crucial to public wellbeing. Renewing the out-of-sight, out-of-mind utilities that power our world needs to become a top priority.
