Millions of miles of utility lines snake beneath our feet, delivering the lifeblood of modern society: water, electricity, gas, and communication. Yet, these unseen arteries are often punctured during excavation, causing disruptions, safety hazards, and hefty costs. Today, we delve into the alarming statistics of damaged utilities during excavation.
The Scope of the Problem:
Frequency: The Common Ground Alliance (CGA) estimates that over 532,000 utility damages occurred in the US alone in 2019, a 4.5% increase from 2018. That's roughly one strike to underground infrastructure every minute!
Cost: The societal cost of these damages is staggering, reaching an estimated $30 billion annually. This includes repair costs, service outages, property damage, and even injuries.
Impact: Damaged utilities can disrupt essential services, impacting homes, businesses, and emergency response. In severe cases, gas leaks or electrical fires can pose serious safety threats.
Causes of the Catastrophe:
Failure to contact 811: Shockingly, over a quarter of all utility damages are attributed to neglecting to call 811, the national one-call center for locating underground lines. This simple step can prevent disaster, yet it's often overlooked.
Inadequate marking: Even with contacting 811, inaccurate or incomplete marking of utility lines can lead to accidental strikes. Clear and precise marking is crucial for safe excavation.
Excavation technique: Using the wrong equipment or excavation methods can increase the risk of damaging buried utilities. Proper training and adherence to safety protocols are essential.
Navigating the Numbers:
Beyond the headline figures, several trends emerge from the data:
Professional culprits: A surprising 60% of damages caused by failing to contact 811 involve professional excavators. Increased awareness and enforcement are needed within the industry.
Infrastructure age: Older infrastructure is more susceptible to damage due to corrosion, deterioration, and incomplete mapping. Targeted investment in upgrading aging utilities is crucial.
Geographic disparities: Damage rates vary across regions, with higher concentrations in densely populated areas with complex underground networks. Tailored prevention strategies are needed based on local data.
Breaking the Ground on Solutions:
The alarming statistics on damaged utilities during excavation paint a clear picture: we need a multi-pronged approach to prevent these costly and disruptive incidents. This includes:
Promoting 811 awareness: Extensive education campaigns and mandatory use for all excavation projects are essential.
Improving marking accuracy: Utilizing advanced technologies like GPS and ground penetrating radar can ensure precise location and clear identification of underground lines.
Enhancing excavation practices: Training programs, safety protocols, and the adoption of safer excavation techniques can minimize risks.
Investing in infrastructure: Upgrading aging utilities and implementing modern mapping technologies can create a more resilient underground network.
By acknowledging the gravity of the problem and taking proactive steps, we can prevent the silent epidemic of damaged utilities from causing further harm. Let's work together to protect the unseen infrastructure that keeps our communities running smoothly and safely.
It is important to understand where public locating leaves off and private locating begins, generally public utility locating ends on private property such as commercial businesses, hospitals and homes. Private locating crosses between the two freely so long as marking standards and safe practices are code compliant. Private companies focus heavily on every utility in the area rather than specific pressurized lines, because of this a private company has access to more equipment such as CCTV cameras and Ground Penetrating Radar Units (GPR). The next time you need to excavate, ask yourself where your project lands between private and public locating!
