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.

DID YOU KNOW…

• Residential customers’ sewer usage bills are based on 85% of total water consumption, allowing a 15% discount for outside water use? If you feel more than 15% of your water consumption is not entering our sewer system, you may benefit from installing a water deduct meter.  The City of Warwick’s
  Water Division (401) 738-2000, ext. 6600 oversees the deduct meter program. CLICK HERE to learn more.

• Fats, Oils, and Grease (FOG) is a leading cause of clogs in the Warwick sewer system? FOG can lead to overflows and sewer backups.  Instead of dumping FOG down your drain, pour or scrapegrease from pots and pans into an old coffee can.  Allow the grease to cool and solidify (refrigerate if necessary) and then throw away in the trash. CLICK HERE to learn more.

• You can call the Warwick Sewer Authority at (401) 739-4949 if you are having trouble flushing your toilets?  Slow flows could be a sign of clogged sewer lines. Our inspectors can assist customers in investigating problems.
