“RAND’s report also provides a more accurate glimpse into the present problem and just how bad it may get.
“‘We found that sewer overflows were actually higher in the 10-year period since 2003 than had previously been estimated,’ Fischbach said. The report concludes that the annual sewer overflows into the rivers are not 9 billion gallons, but as much as 11 billion gallons.
“Fischbach’s group also ran thousands of simulations to see how the sewer overflows will be affected by climate change and population growth. ‘We looked out about 25 to 30 years with different scenarios and, depending on the scenario, we saw that overflows could continue to grow at 15 to 40 percent greater than 2003.'”
