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

Benefits include but are not limited to: compliance with local, state and/or Federal laws and regulations as it reduces the chemicals released into the environment; an immediate reduction in consumption and water dumped to waste after each test; Improved customer perception as the Water District sets an example for water conservation practices.

Learn More about MARS Recirculation Systems

• Utilizes municipal (public) service to supply the needed water to the test system
• The water is drained from the measurement tank and then directed to the storm drain, municipal sewer, or wherever the user sees fit
• The water service must be able to provide a pre-determined flow at a specific pressure (requirement depends on bench size and specifications) in order to achieve proper test results
• Not recommended in situations where the cost of water is high or water conservation is desired

With MARS Certified, you can protect both MARS and selected third-party equipment with technical assistance, software upgrades, preventative maintenance, spares management and on-site maintenance.

Not only is the equipment upkeep essential, but ensuring all operators are fully trained on meter testing practices and procedures is critical.
