The history of vacuum excavation is honorable, but the future is crucial Construction sites all over the globe rely on vacuum excavation. Each underground construction company, no matter how big or small, wants to make sure that their workers are healthy and able to finance their projects. It can be difficult to find the right machine in today's highly competitive market. Vacuum excavation reduces time and improves safety by avoiding damage. The evolution of these machines will enable contractors to have a better understanding of their technology and the ways that they are changing underground construction. The origins of vacuum excavation can also be traced back to hydro-excavation, which began in 1800s America when water flow was controlled by pressure. This was the method used to excavate soil using pressure water. It is safer and more efficient than traditional methods. Hydro excavation was later extended to include construction sites beneath the surface of the majority of Canada and the United States. At the start of the 20th century, there was a need for vacuum excavation services using. This led to new designs which were focused on optimizing performance at various construction sites. For example, residential construction projects saw an increase in excavators' use due to lower noise levels. The technological advancements made in nozzles have been focused on improving digging capacity and decreasing the risk of underground utilities being damaged. Larger tanks allow machines to stay in service for longer periods of time and have greater hauling capacity, which improves contractor efficiency. Some municipalities have seen a 50 percent increase in efficiency with larger tanks.
They have also been adapted to smaller job site requirements. The smaller tanks and machines allow for easier operation. This allows operators to move more efficiently in tight spaces. Air excavation is now more important than mechanical upgrades. Many contractors were skeptical of the benefits of air excavation. Many contractors have found air excavation to be a vital tool due to its cost-
