From the Aurora Sentinel (Sara Castellanos):
Aurora’s sewer water is treated by the Metro Wastewater Reclamation District, so when their rates go up, Aurora’s residents feel the effects as well.
New Environmental Protection Agency rules require the reclamation district to remove nitrogen and phosphorous in wastewater before they put the water back into the South Platte river, said Greg Baker, Aurora Water department’s spokesman.
The cost to remove the chemicals is more than $500 million, so the district is charging Aurora Water 8 percent more to treat the wastewater, he said.
Aurora Water is absorbing some of the costs, so residents could see their sewer water bills increase 4.1 percent through 2016. But Aurora City Council members have to make the final approval on the increase in October. The changes would take effect Jan. 1, 2012.
