Explanation
1.0 BACKGROUND: This Ordinance authorizes the Director of Public Utilities to modify and increase the professional engineering services agreement with Brown and Caldwell for the Hap Cremean Water Plant (HCWP) Lime Slurry Disposal Line Condition Assessment Project, Division of Water Contract No. 2041.
This project consists of three phases. Each phase is intended to build confidence in the capability of the in-line inspection technology before moving to the next phase.
Phases 1 and 2 were legislated under Ordinance No. 0760-2014, passed April 28, 2014. Phase 1 consisted of the condition assessment of a 12” water distribution main using an in-line inspection tool. Phase 2 consisted of the condition assessment of the DRWP 14” lime slurry disposal line and a pilot section of the HCWP 12” lime slurry disposal line.
The in-line inspection technology provided acceptable results in Phases 1 and 2, therefore, Phase 3 is ready to commence. Phase 3 will consist of the condition assessment of a two mile section and a 3 mile section of the HCWP lime slurry disposal line between the end of Phase 2 and the McKinley Quarry.
