 On November 19 , 2001 , construction crews , while preparing to drill an electrical conduit ( consisting of six large <unk> electrical cables ) across the creek for the <unk> Metro T Third Street light rail line , cracked the concrete sewer underground which carries more than 80 million gallons of sewage a day .

It was estimated that it would take more than $ 101 @,@ 660 to repair and $ 65 @,@ 000 for wildlife habitat restoration .
