Beach Closures and Rainfall by Year 2000 — 2014
- Beach closures in Rhode Island are closely tied to precipitation. Stormwater runoff from roads, parking lots, and other impervious surfaces transports contamination (including bacteria) to our fresh and salt-water bodies. As demonstrated by the graph above, the correlation between rainfall and beach closures has changed dramatically since 2009, when Phase I of the Narragansett Bay Commission's "Combined Sewer Overflow Abatement Program" came online. A system of tunnels constructed beneath Providence store combined sewer and storm water during heavy rainfall events. Once the storm has subsided, the combined sewer and storm water goes through a wastewater treatment facility before entering Narragansett Bay. Phase II of the Combined Sewer Overflow Abatement Program became operational during the end of 2014. more
In addition, numerous municipalities including Barrington, Bristol, and Newport have installed stormwater improvement projects at and around their beaches. The City of Warwick has removed thousands of cesspools and installed municipal sewer connections in the Oakland Beach area. These cities and towns have seen improved water quality (and fewer beach closures as a result). Additional municipalities are in the process of installing systems to improve the quality of water at their beaches.
