An alliance between the public and private sectors is one of the most efficient and cost-effective ways to provide safe water reliably in the face of aging infrastructure, growing demand, and increasing complexity of water management.  For these reasons, the Borough of Allendale has partnered with Suez to carry on the commitment of providing Allendale residents high-quality drinking water.

At Suez, we’re proud to lead by example in providing safe drinking water and protecting the nation’s waterways since 1869. Our relationships save clients hundreds of millions of dollars, bring multiple systems into compliance and ensure a safe supply of water for generations.  For more information on Suez in Allendale, please refer to the website.

Various pamphlets have been created in order to ensure that all Allendale residents are informed of each step of the water payment process.  Feel free to explore these packets by clicking on the links below.

Notification of  After Hour Emergencies
In the event of any emergency, such as water main breaks, the water utilizes the Reverse 911 system, to notify residents by phone with an automated message.  If you experience an after-hour emergency, please contact Suez at (201) 487-0011 or the Allendale Police Department at (201) 825-1900.


Final Bills
If you are moving or selling your business, you must call Customer Service at (855) 367-6708 at least 5 days before the property closing date; landlords must notify Customer Service five days before a tenant moves out of or into a property.  When scheduling a final reading, all account information will be taken.  At the end of this scheduled reading, a final bill is generated and must be paid in order for the account to be closed.


Water Testing
Each year, numerous water samples are collected and subjected to over 1,000 tests.  These samples include organic and inorganic V.O.C.s, which are tested for natural and man-made contaminants in the treated and untreated water supply.  Other tests include bacteria, lead, and copper.  All test results are filed with the NJDEP, an agency responsible for monitoring and regulating the drinking water in New Jersey.
