After originally awarding the city of Auburn $600,000 to install a powder-activated carbon system to treat microcystins in the city's drinking water, the state agreed to increase the award to $750,000.
Director of Municipal Utilities Seth Jensen said during Thursday's Auburn City Council meeting that the city requested the extra money to purchase additional chemicals, as well as for project cleanup. Jensen said the additional money will provide a buffer for any unanticipated future work.
The system has been up and running since Friday, Aug. 4.
"So far, we're very pleased with the unit and how it worked," Jensen said.
