MARS Large Bench Recirculation System

MARS Recirculation Systems - Large

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 configuration of MARS Large Bench Recirculation Systems.
* Denotes Optional Items, contact MARS for details.

Storage Tanks

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

Redundant Supply*

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).

Reduced Usage

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.

Return Pumps*

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

Ease of Maintenance*

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

Standard System Specifications

Specifications are subject to change at any time.  Please contact MARS for the latest specifications.

Additional Recirculation System Specifications


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


Filtration System

Automatic timer
