Water Tanks for Rigid-Frame Trucks

  • Perfect for dust suppression, fire protection, road construction, wash down and other applications.
  • HiVol Water Tanks for articulated off-highway haul trucks come in sizes from 9,500 to 90,000 gallons.

When it comes to safety and reliability, differences in design are what make PHIL HiVol® Water Tanks the best solution for any quarry or construction application. They deliver superior safety, simplified maintenance and quality you can rely on day in and day out. After all, nothing can slow or stop your operation quicker than an unreliable water truck.

Higher quality construction and custom designed

Every HiVol Water Tank is constructed of superior grade steel – a higher grade of steel than any other water tank on the market – which resists corrosion and rust. We are proud to say that every HiVol Water Tank built of this steel shows no signs of corrosion or rust to date.

We customize the design of each HiVol Water Tank based on the characteristics of your operation. Every application has its unique requirements and every HiVol Water Tank is designed to meet those particular requirements.

Safety is Built-In - Options Are Not

PHIL doesn't skimp on safety; we never have and never will; a lack of safety is not an option.  All PHIL Water Tanks offer the same unparralelled safety whether it's in the form of walk-through exterior access doors, internal baffle doors, minimized confined spaces, free flowing air, our flat-top design or our side-surge stabilisers - they all come standard.

But, instead of loading up your tank with a ton of options you don't want and charging you for them, PHIL quotes the base tank and then adds the options and components you want and need to get the job done - efficiently.  Are you interested in maintaining complicated hydraulics or plumbing that's unnecessary?  We didn't think so.  After all, it's easy to design something complicated, but takes a lot of extra effort and skill to destil a design to simplistic beauty.  And that's what we offer you.

Patented tank design

Our patented fluid tank baffling system compartmentalizes the water in order to prevent surging and ensure truck stability in any application. Front-to-back baffling and our patented Bacbone™ structure work together with internal fluid surge stabilizers to minimize side-to-side churning for maximum control on haul roads.

This system includes exclusively patented exterior doors and interior man-sized access doors with rust-proof pivots located throughout the tank, allowing natural light to enter and minimizing confined space. The doors simplify maintenance and allows for unrestricted access to any part of the tank interior. No more crawling around in dark water tanks!

The exterior of our tanks are designed with a unique flat top. With virtually no slope, it provides safer footing. In addition, our exclusive lifting eye design provides precise placement for perfect balance when raising the tank.

Simplified water control

Every HiVol Water Tank is equipped with rear-mounted spray heads that operate independently, allowing you to utilize any number of spray heads (or all) at the same time. Also, an optional in-cab remote controlled water cannon is available that can disperse water from 150-200 feet on each side of the tank with precise control and accuracy.

Employing an exclusive Soft-Start/Soft-Stop hydraulic valve, you can safely start and stop the water pump at any engine RPM. This allows you to quickly turn the water on at full throttle without damaging your pump. Also, our exclusive Variable Volume feature is an option which allows you to control the water volume with a simple adjustment.

The plumbing system utilizes "Victaulic-style" fittings and has no welded connections, for simple and easy maintenance. The spray heads can also be rebuilt to minimize maintenance costs..

Greater truck utilization

HiVol Water Tanks allow you to haul water to full truck capacity, whereas competitive tanks allow only around 80% utilization. For example, a 40-ton articulated truck with a HiVol Water Tank can haul up to 10,250 gallons of water, but only 8,000 gallons with a competitive tank.

Items to consider when purchasing a water tank:

Chassis Hoist System

  1. Are Hoist Cylinder Mounts put on the water tank? This requires some type of three-way hydraulic valve and plumbing system to switch from raising the water tank to the operating of the water tank hydraulic water pump motor and finally adding a hydraulic function. (And be sure that the chassis hoist cylinders are in a "float" function for normal water tank operation).
  2. Also, are the Chassis Hoist Cylinders disabled (removed from the chassis), which requires some type of water tank tie-down arrangement?

Variable Volume

  • Does the tank you're looking at offer a Variable Volume option that allows the tank to be filled to various levels other than 100% and is used whenever less than a full load of water needs to be carried?
  • Variable Volume is an excellent feature for training of water tank drivers, or when used in operations that have steel grades on their haul roads.


Multiple points of Ingress / Egress

  • Does the water tank provide a minimum of two (2) top of tank fill ports?
  • Are the fill ports square (square fill holes allow for easier ingress/egress and provide 33% additional  surface area, which provides a much easier position for filling the tank from the horsehead or other fill pipe)?
  • How many access doors are on the front and back of the water tank? Any less than three (3) extrernal access doors allowing for easy and convenient access to the inside of the water tank from the front and back minimizes an operators ease of access, and restricts natural light and airflow from within the tank.


What it's Made Of

  • Water tank manufacturers build water tanks out of a wide range of grades or strengths of steel ranging from 50,000 psi yield through 185,000 psi yield of steel. But, the characteristics of the steel and how it holds up to water, moisture, air, rust and corrosion is important.
  • Let's take into consideration what's involved in a water tank that holds 58,500 US gallons (221,500 liters). This is a 240 ton payload; the water tank has to have the structural strength to carry 240 tons without compromoise. Hence, to keep the tank weight reasonable, a PHIL water tank is made from 185,000 psi yield steel. How does that compare to the alternative?


Water Quality & How Design can Enhance Water Tank Life

  • Water Quality can sometimes be an issue when the pH is very alkaline or acidic.  When this is the case, sacrificial anode/cathode water tank protection may be required.  If you have other water tanks operating, they would be the best indication of any extreme corrosion protection being needed.  However, by its very nature, 185,000 psi yield steel is much more corrosion resistant than lesser yield steels.


Water Surge & Safety

  • When operating and hauling water, extreme water surges will impact safe stable vehicle operations.  To minimize the impact of water surging, there should be NO internal water tank baffle HOLES larger than about 250 cm or 10 inches in diameter.  All water tanks have internal baffles in one form or another, but if you really want to have solid a water tank operation, limit ALL baffle holes to less than 250 cm or 10 inches in diameter.
  • When internally inspecting water tanks (and it should happen at least annually, IF easy to do), internal unrestricted personnel movement is a must. And just as PHIL Water Tanks have external ingress and egress doors, so do the Water Tank baffles likewise have personnel doors that close to restrict water movement when the tank is being used, but easily open for personnel access within the tank, providing more opportunity for natural light and free flowing air to travel throughout the tank and its baffles.
