CAT CLASS: HQ-10911

500-2,000 gal Water Tank

The 500-2,000 gallon water tank class provides mid-capacity portable storage for site water applications including hydro-seeding operations, soil compaction, and temporary supply where municipal connections are unavailable. This size sits between the smaller up-to-500-gallon tanks suited for spot watering and the 2,000-6,000 gallon units built for large-scale dust suppression and high-volume irrigation. Tanks in this range are offered by Den Hartog, Plastic-Mart, Norwesco, Chem-Tainer, Poly-Mart, Snyder Industries, Dura-Cast Products, and Western Global across 144 models.

Key specifications

SpecificationTypical rangeWhat it means
Capacity500–1,850 gallonsVolume range defines water supply duration for hydro-seeding pumps and compaction equipment without refilling.
Load Capacity1,102–4,079 lb (500–1,850 kg)Structural rating for filled tank weight; filled 1,000-gallon tanks weigh approximately 8,300 pounds including water.
Max Height6.2–47 ft (1.9–14.3 m)Overall height when mounted; taller vertical configurations increase static pressure at outlet, lower horizontal designs improve transport stability.

How to choose

This capacity band suits jobs requiring sustained water delivery over several hours without refill — typical hydro-seeding crews running 50-gallon-per-minute spray systems, compaction operations cycling water trucks, and temporary potable supply for small crews. For hand-watering, landscaping finish work, or single-pass equipment where a 500-gallon supply suffices, the Up to 500 gal Water Tank class offers easier handling and placement. When supporting large erosion-control projects, multiple concrete pours, or multi-day dust suppression across extensive acreage, the 2,000-6,000 gal Water Tank band delivers the volume needed to minimize water-hauling downtime.

What this size handles

  • Hydro-seeding 2–4 acres of roadway shoulder with tank-fed spray rig
  • Compaction water supply for subgrade and fill operations on residential subdivision
  • Temporary potable water for 8–15 person crew on remote jobsite
  • Dust control watering during grading and trenching on commercial site
  • Fill water for concrete mixing trucks where municipal hookup is distant
  • Irrigation reservoir for landscape installation crews over multi-day projects

Safety & operation

  • Filled tank weight shifts center of gravity; transport and placement on uneven ground requires blocking, leveling, and assessment of soil bearing capacity.
  • Outlet valves and hose connections must be secured against accidental discharge; sudden release of 1,000+ gallons creates washout and site hazards.
  • Potable water tanks require NSF/ANSI 61 certification and periodic sanitation; non-potable tanks must be clearly labeled to prevent cross-use.
  • Vertical tanks exceeding 8 feet in height require anchoring or tie-down in high-wind conditions to prevent tipping when partially filled.

Transport & logistics

  • Tanks up to 1,000 gallons typically trailer-mounted or skid-based for pickup bed placement; filled weight requires 3/4-ton or larger tow vehicle.
  • Larger units in the range ship on dedicated water-tank trailers with integrated pump and hose reels; highway transport requires commercial towing capacity.
  • Empty tanks may be fork-lifted onto flatbed trailers; filled transport requires securing against surge and weight distribution per axle ratings.

Power & supply

  • Most tanks in this class are unpressurized gravity-feed reservoirs; dispensing requires auxiliary 12V or gasoline-powered transfer pumps.
  • Site filling performed via municipal hydrant connection, water-truck transfer, or portable pump from well or pond source.
  • Pump-equipped models draw from 12V vehicle electrical systems or dedicated small gasoline engines (3–5 HP) for self-contained operation.

Frequently asked

What refill frequency does a 1,000-gallon tank provide for typical hydro-seeding?
A 1,000-gallon tank supplies approximately 15–20 minutes of continuous spraying at 50–60 gallons per minute, covering roughly 1 acre per fill depending on application rate and seed mix.
Can tanks in this range be filled from fire hydrants?
Most municipalities allow hydrant filling with a meter and backflow preventer; confirm local ordinances and obtain permits, as flow rates of 100+ GPM can fill a 1,500-gallon tank in under 20 minutes.
How does tank configuration affect site placement?
Horizontal leg tanks (lower profile, 6–8 feet tall) fit under overhead obstructions and offer stable transport; vertical tanks (10+ feet) save ground footprint but require overhead clearance and anchoring on soft soils.
