Test Bench Recirculation Systems

Previous slide
Next slide

The MARS Recirculation System recycles the test water used on the MARS Test Bench System(s), maintaining volume and pressure to test all the meters at the recommended AWWA Specifications, per Table 5-3 of the current AWWA M6 Manual.

MARS Test Bench Systems are designed to meet / exceed American Water Works Association (AWWA) recommendations, National Institute for Standards and Technology (NIST) Handbook 44 Specifications, ISO Specifications and other standards and requirements.

Advantages of Recirculation Systems

Compliance with local, state and/or Federal laws and regulations as it reduces the chemicals released into the environment

An immediate reduction in consumption of test water

An immediate reduction in water dumped to waste after each test

Improved customer perception as the City sets an example for water conservation practices

Standard and Optional Features

Available on every Test Bench Recirculation System configuration.
* Denotes Optional Items, contact MARS for details

Size dependent on configuration, as tanks and pumps can optionally service multiple benches.

Systems are equipped with filtration and chlorination to ensure clean test water.

Offers the ability to use either city or recirculation for supply, making a redundant system (i.e., if one system is inoperable, the other can be used).

Utilizes a storage tank and system of pumps and VFD’s (if necessary) to recirculate water through the test bench, minimizing overall water use.  

Under normal conditions, municipal water is only used to fill recirculation tank and maintain sufficient water levels during operation.

Requires a return pump (unless re-circulation tank is below measurement tank) and pump to direct water from the measurement tank back to re-circulation tank.


  • Fabricated steel
  • Welded in accordance to standard industry practices and certifications


  • Polyester Coating in MARS Blue
  • Minimum of 20 years resistance to corrosion
  • High impact resistance
  • All steel is fully sandblasted and treated with Atochem rust proof primer before being coated for total bonding
  • Frame is not touched by human hands within at least 2 hours of drying
  • Coating is applied using the electrostatic method, then placed in an oven at 495 degrees F until fully bonded
  • The frame is electrostatically spark tested to detect defects

Tanks and Piping

  • Properly sized polyethylene or stainless steel tank (dependent on configuration)
  • All related piping and valves are included


  • Supply pump(s) (one for each Small Meter Test Bench and two for each Large Bench)
  • Return pump(s), based on the number of test tanks within the system
  • The number of VFD’s is predicated on the number of supply pumps and Test Bench System within the configuration
  • VFD panel / enclosure

Chlorination System

  • Pump
