In order to protect the water delivered to customers from contamination in the distribution system, NMWD has a comprehensive Cross Connection Control and Backflow Prevention program.

The aim of the program is to protect the potable public water supply from contamination.
NMWD staff identify areas or properties where risks might exist, categorize those risks, and apply the appropriate devices to reduce or eliminate risk.

You may need to have your property evaluated and have the proper device installed if you have any of the following on your property:

• An auxiliary water supply (such as a well)
  • A pump due to low pressure
  • A water storage tank
  • Dock side water facilities

All commercial and industrial facilities are required to have a backflow prevention assembly installed at the meter.
