As southeast Michigan continues to bake amid rising summer temperatures, the number of illegally opened fire hydrants in Detroit has doubled in June from a year ago.
Monday's highs hit 97 degrees in Detroit, 100 in Ypsilanti and 99 in Oscoda.
Detroit fire officials say people illegally opened 884 hydrants last month, up from 426 in June 2011. They say open hydrants could result in higher water bills for homeowners and headaches for Detroit firefighters.
Detroit Fire Capt. Gregory Turner tells The Detroit News "every second counts" for firefighters who rely on consistent water pressure.
Officials say on last month's hottest day June 28, people opened 190 hydrants citywide.
About 2,000 redesigned locks have been installed on Detroit's 27,244 hydrants since 2005. Each costs $256..
