A Message from the MLMUA for their Commercial Customers

As New Jersey prepares for “The Road Back”, make sure your business is ready to meet the challenge!

If your business/building has been completely or partially unoccupied during the current pandemic, you must take action to address possible water quality degradation in the building’s plumbing system.  This correspondence is intended to bring awareness to this issue.  We also provide basic guidance and a helpful link so you can reoccupy your building in a “water healthy” way and avoid water quality issues.

What happened to the water while the building was unoccupied?  Examples include:

  • When water was not used, the chlorine in the water had a chance to dissipate.  This invites microorganisms to grow inside pipes, fixtures and tanks.  Some may cause disease if they are consumed or inhaled as droplets (particularly while showering).
  • The protective scale inside pipes may have destabilized. Without the protective scale, toxic metals like lead (if you have lead pipes) can dissolve or shear off as particles and end up in water used for drinking or food preparation.
  • For larger buildings/systems, mechanical equipment such as cooling towers, boilers and pumps may not have received routine maintenance.  Backflow preventers may have missed annual test cycles.

What actions do I need to take?

Every business is different and the answer to this question varies depending on the size, design and use of your specific plumbing system.  The proper actions will range from the simple flushing of your plumbing system for a few minutes to following the actions put in place as part of your Water Management Plan (if applicable).  Size, design and use are important in determining your actions.

The link below provides some basic information and guidance which will allow you to take appropriate actions.  This will ensure that a return to normal includes water quality in your building that is tailored to your specific needs.  If during this process you have any questions, our water professionals will do their best to assist you.   You are invited to contact us at 856.234.0062.
