Water Tanks
0 companies listed
Water tanks store the clean water used for hydrovac excavation. Tank size, material, and insulation directly affect how long a crew can dig before refilling and whether the unit can operate in freezing conditions.
What to Look For
- Capacity matched to your typical job duration and water source availability
- Insulation and heating capability for winter operations
- Material (poly, aluminum, or steel) and weight impact on payload
- Baffling to prevent water surge during transport

Frequently Asked Questions
What size water tank do I need for hydrovac work?
Most truck-mounted hydrovacs carry 300-1,200 gallons. Potholing crews typically use 300-600 gallons per day; high-volume excavation may require 1,000+ gallons.
How do heated water tanks work on hydrovac trucks?
Onboard boilers or water heaters raise water temperature to 140-180 degrees F, allowing excavation in frozen ground. Some systems recirculate water through the tank to prevent freezing overnight.
