Public Service Announcements



Notice of sewerline flushing for September 2017 & What NOT to Flush 

 The Warwick Sewer Authority (WSA) strongly encourages homeowners whose properties are connected to sewers to contact the WSA at the first sign of trouble with their sewer system.  WSA inspectors are available to respond to a customer’s call and will investigate the nature of the problem.  If the problem can be traced to the public sewer collection system, WSA will make the necessary repairs and improvements to the system.  If it is determined that the public sewer system is functioning properly, WSA inspectors may be able to assist homeowners in addressing problems with their private service connection. 

 You can reach the Warwick Sewer Authority by calling (401) 739-4949; when prompted, enter “1” for sewer emergencies.
