Metropolitan Government of Nashville

$7.5 million

Description:

This project was a unique performance-based design-build contract to remove I/I from a 20,000-acre sewer basin in Nashville. This 5 year, $7.5 million contract is the first of its kind, whereby the Reynolds' team guaranteed 20 percent I/I removal with an additional monetary bonus if 30 percent removal is achieved. The project included:

  • Analysis of flow and existing investigative data
  • Establishment of base flows to the system
  • Engineering and prioritization of rehabilitation efforts
  • Preparation of rehabilitation plans based on existing data
  • Work plan, including conducting wet weather monitoring, inspection and construction
  • Field investigations (smoke testing, CCTV, manhole inspections, etc.) of the existing system
  • Efficient tracking of the investigations and completed work through creation of a comprehensive database system
  • Selection of most efficient and cost-effective rehabilitation activities (all per Nashville specifications), including sewer relining, service lateral renewals and manhole renewal with a variety of methods
With more than 90,000 feet of CIPP installed, combined with 800 service lateral renewals and miscellaneous manhole rehabilitation, total I/I reduction was 41 percent, greatly exceeding the 20 and 30 percent goals.
