Unlike a traditional water storage system, the water tank stores water and unleashes it onto the excavation. The operator uses a wand to spray the water into the soil, which softens it and loosens debris. Blasting water over the solid ground can be amusing too!

Another crucial component in the hydro excavator is the vacuum hose; think of it as a straw, but instead of sipping, it sucks up debris. Reinforced with steel wire to prevent it from getting crushed and plastic waste from getting stuck, it’s known to be virtually indestructible.

Like the machine’s heart, the water pump is responsible for pumping water with force and passion to move through the hose and wand. This is what makes hydro excavation different from anything else. The hydro excavator uses high pressure to force water out of the wand, making excavation and removing soil and debris a breeze.

Last but not least, let’s talk about the boom. It’s what makes everything possible – think of it as a helping hand for the operator. With the boom’s flexibility, the operator can swivel, adjust and extend it to position the hose and wand accurately over the excavation site, making digging easy, convenient, and effective.

When working together effectively, these techy components make hydro excavation the preferred option for excavation work. Not only is it faster and more efficient than its counterparts, but it’s much safer, too, making it a game-changer in the excavation industry.
