Asset Management/Capital Efficiency Plans™
Norwich, Connecticut
Tata & Howard completed a comprehensive Capital Efficiency Plan™ for Norwich Public Utilities (NPU) in 2009. The Capital Efficiency Plan™ followed our three circle approach including a system hydraulic evaluation, critical component assessment and asset management considerations. The NPU distribution system is comprised of approximately 180 miles of water mains of various material types with pipe ranging in diameter from 2 to 30-inches. During the course of the project Tata & Howard worked closely with NPU staff and other City of Norwich Departments. Meetings and workshops where held with operations and engineering departments as well as with the numerous fire departments that cover the greater Norwich area. The final report included a prioritized list of recommended water main rehabilitation and replacement projects and the associated estimated costs for those projects. In addition, water storage tank stagnation issues were identified. Since completion of the Capital Efficiency Plan™, NPU authorized Tata & Howard to complete a system gradient study that evaluated how to significantly improve water quality in the distribution system and adjust system pressures to reduce system leakage while maintaining an appropriate amount of system storage. NPU has further authorized Tata & Howard to conduct preliminary engineering analysis that will lead to the design and construction of new storage tanks, pump replacements, water mains and energy saving alternatives.
