The $28 million Macomb Interceptor rehabilitation project includes installing a giant pipe along 15 Mile Road in Sterling Heights to prevent disasters such as the Fraser sinkhole that opened in late 2016. Candice Miller, Macomb County public works commissioner, said the sinkhole of Christmas Eve 2016 in Fraser cannot happen again but almost did when she got cameras into miles of old sewer lines.
