Public Service Announcements

Winter Storm Alert:  In anticipation of the potential for power outages during the upcoming storm, the Warwick Sewer Authority is reminding its customers with grinder pumps that, if power is lost, the pumps will have limited capacity and those customers should therefore limit water usage; without power, the grinder pumps will be unable to discharge into the main sewer line.  WSA suggests that grinder pump owners prepare for a power outage by running an inside faucet for about 10 minutes or until the pump starts up. This will evacuate any wastewater stored in the pump and maximize storage capacity.  Continued reduced water usage will allow for use of the plumbing facilities for a longer period of time, hopefully until power can be restored.  If there is an extended power outage, WSA will issue additional information and guidance.  Please read this Grinder Pump "what happens when the lights go out?"what happens when the lights go out?" guide.


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.

Welcome to the Warwick Sewer Authority

Our mission is to provide wastewater collection and treatment services to the City of Warwick in a cost effective and environmentally sound manner.

The Warwick Sewer Authority was created in 1962 by Rhode Island Public Law 1962, Chapter 254, Section 2 as an enterprise fund. There are approximately 250 miles of sanitary sewer lines and 45 sewage pump stations within the City used to convey wastewater. Warwick’s Advanced Wastewater Treatment Facility uses modern processes and equipment to treat wastewater and remove most of the pollutants before discharging into the Pawtuxet River. Ongoing sewer construction projects continue to expand the WSA sewer system in order to provide services to eliminate or minimize environmental, safety and public health problems.

With thirty-nine miles of coastline, beautiful beaches and coves in the City of Warwick, the Warwick Sewer Authority is committed to sustaining our natural resources. In conjunction with Save the Bay, Coastal Resources Management Council and the Rhode Island Department of Environmental Protection, the WSA has implemented a Mandatory Sewer Connection Program, mandating connection to available sewers throughout the City. Increased participation in our sewer system will significantly improve water quality within the Narragansett and Greenwich Bay watershed areas.

As you navigate our updated website, we hope you find it a valuable resource. As always, employees at the Warwick Sewer Authority are available to answer any questions you may have. Please contact us at (401) 468-4700.
