During spring utility projects, problems and concerns should be the last thing blooming. As winter weather makes its way out, excess water and softening ground should not stand in the way of repairs.
Hydro excavation, a process that removes soil and debris in a variety of conditions, offers one solution. The process utilizes pressurized water and a powerful vacuum for precise digging without damage to underground utilities and natural elements.
TRUVAC shared some reminders for springtime hydro excavation projects.
1. Form a Plan
Soil type, along with debris and water content, are always factors to look out for before taking on a hydro excavation project. While heavy rain and flooding can cause sandy soil to become compacted, making it easier to remove debris, springtime conditions can be unpredictable. Make a plan for steps to take in various potential situations.
2. Consider Thawing Ground
Soft ground and flooding are common during spring jobs, but frozen conditions can be hidden below. As in winter weather, the hydrovac may still require heated water to get the job done.

3. Know the Debris Capacity
As snow melts and rainfall increases, there may be more muddy or wet debris on a site. Hydrovac trucks have a debris body capacity ranging from five to 15 cubic yards.
4. Consider the Vacuum Source
There are two main options when considering the vacuum source for hydro excavation: a fan system or a positive displacement (PD) blower. For springtime projects, PD blowers can be beneficial due to their ability to pull heavy, wet material over long distances.
5. Follow Safety Protocols
Hydro excavation promotes worker safety by minimizing the need for manual labor. However, proper personal protective equipment such as hard hats, long sleeves, and gloves are necessary for operators regardless of site conditions and temperature.
6. Practice Proper Maintenance
Debris can accumulate on hydrovac tanks and become difficult to remove. Dry, sandy soil tends to create the most buildup, so spring conditions can help reduce concerns. However, it is important to store hydrovacs in a clean, dry environment during wet seasons to prevent buildup on the tank.
