The $2.3 million is in addition to the $6.2 million voters approved in 2021. If voters approve the additional borrowing, the commission will have enough money to replace two water storage tanks. If they do not, only one of the tank projects will be done now. The original $6.2 million was for both the tanks and the replacement of 4,000 feet of water mains under Case Avenue, Center Street, Greenwood Avenue, Thibault Avenue, and the eastern section of Holabird Avenue, from Whiting to Florence streets. Those projects were estimated to cost $6.2 million three-and-a-half years ago, prior to the COVID-19 pandemic, Public Works Director James Rollins has said. Since then, costs have risen 37%, to $8.5 million. The water main project cost $2.2 million, $833,000 more than what was originally projected, Rollins has said. But that project is covered with the $6.2 million.
