Hydro excavation is a new process that is becoming popular because of the benefits that it provides. These benefits include environmental protection. This is especially important when it comes to cold weather digging and is one of the major concerns of developers. They need to take into consideration the impact of the changes they will be making to the environment. Cold weather digging is traditionally a process that causes a lot of pollution. Hydro excavation reduces this problem a lot.
The hydro excavation process does not contaminate underground water reservoir. It also does not have any risk of damaging gas reserves, pipelines, sewers and fiber-optic cables since the water pressure used in excavating is very accurate. Traditional excavation methods bring with them safety risks for the laborers, nearby citizens, utilities and the environment. The machinery and chemicals involved in these methods can cause accidents and contamination.
For jobs where pipes need to be checked, exposed or installed, hydro excavation is also able to dig the soil in a way that the pipes will not be damaged. The pipes and underground utilities are avoided by the water so there will be no leaks or cracks made.

Cold Weather Digging with Hydro Excavation
Digging for pipes, posts, signs, poles, etc. in cold weather is a bit more difficult than digging in normal weather. The ground is frozen and a lot harder than usual.
Earlier methods for digging in cold weather involve thawing the frozen soil first. Coal and wood are used to thaw the ground before a backhoe is used to excavate. Manual digging may also be done after the soil is already softened.
This process takes a lot of time. The digging itself is long process, especially when digging manually. Thawing soil makes the process even more time consuming. Also, the chemicals from the wood and coal are dispersed into the air once they are burned. This causes harm to the environment.
The process of hydro excavation is able to solve these problems. The hydro excavation trucks are equipped with heaters. This allows the water to be able to excavate through frozen earth and ground frost. Using hydro excavation for cold weather digging reduces labor cost considerably. It also reduces labor and material costs.
Traditional methods for digging through frozen soil involved thawing through wood and coal. This was very dangerous for the environment. Hydro excavation provides a 100% environment friendly process. The fire hazards from thawing the ground are also eliminated. Since thawing is not needed, the amount of time to finish the excavation is lessened.
Hydro excavation is a safe process because it only involves water and air vacuum. The excavation trucks can be positioned far from the actual excavation site. This keeps the contractors away from the only machinery or equipment involved.
