摘要

The Pleasant Run Deep Tunnel is a 39,900-foot long component of the 28-mile long Diglndy deep rock tunnel system, the cornerstone of Citizens Energy Group's Long Term Control Plan (LTCP). Final planning optimized the conceptual design to achieve CSO capture objectives while eliminating expensive components and saving millions of dollars. The capacity of existing infrastructure was optimized by raising or adding weirs instead of installing new diversion structures and consolidation sewers. The number and length of required adits were minimized by optimization of the tunnel alignment and selection of drop shaft locations closer to the alignment. Several drop shafts originally planned were also eliminated. The overall level of control is expected to exceed LTCP requirements.
