As in the 2010 survey, Florida and Minnesota have more than 100 SWUs, but Washington and Wisconsin joined the 100 SWU club this year. Arkansas has its first stormwater utility (Hot Springs) so that there are now 39 states and DC with SWUs. Though we do not include them in our survey, there are now several SWUs in Canada. Figure 1 shows U.S. stormwater utilities by location.
