(Cambridge City, IN)--An engineering firm has presented cost estimates for wastewater treatment at the Gateway Industrial Park near Cambridge City. Without an expansion, tenants like SugarCreek – and the park itself – cannot grow. The firm said the cost of sending wastewater to Connersville would be $22.4 million. Building a new treatment facility on site would cost between $13 and $16 million. Sending the wastewater to Connersville would require the installation of a 24-inch line. Sewer Board President Tom Lee has said he favors the Cambridge City option.
