A program management approach was used to assist the Northeast Ohio Regional Sewer District (NEORSD) in getting the largest Capital Improvement Program (CIP) in its history underway through management assistance of design projects and consultants, technical support during implementation, construction administration and assistance with regulatory negotiations. The CH2M HILL and Wade Trim Team served as the Program Manager supporting the delivery of the Collection System, Plants and Combined Sewer Overflow (CSO) Programs from 2008 to 2013. Our team provided support in program management, design management, program controls, project definition identifying optimal cost reducing strategies, general and CSO based technical support, hydraulic modeling and maintenance, post construction monitoring plan development, and staff augmentation, where needed to assist the District with project delivery.
The $3 billion program includes collection system and plant upgrades as well as a 21-mile network of 7 large-diameter tunnels constructed in rock and soft ground. The tunnels capture CSO, currently entering Lake Erie and its tributary streams, for treatment at the District’s three wastewater treatment plants after each rain event.
Extensive modeling efforts were undertaken to support CIP projects including surge modeling for two tunnels and collection system model upgrades. Standards and protocols were developed to ensure model consistency and compatibility moving forward. This laid the groundwork for a more efficient model management system for supporting future design projects and annual reporting of CSO control performance.
