Improvements for Growth, Reliability, and Redundancy

Phase 1 Conceptual Layout

Phase 1 Project Financial Summary

Planning Level Estimate $14 Million

Actual Project Cost ($12.8 Million)

Savings $1.2 Million

Anticipated CPU Energy Incentive

$0.32 Million

TOTAL SAVINGS $1.52 Million

Design Phase Cost Savings: MBR Equipment Preselection

MBR: Preselection required to proceed with final design►Variety of MBR Configurations►Space Requirements►Performance/Reliability►Hydraulics►Equipment Footprints

MBR Preselection

Steps:1.

Facility Planning –

Initiated contact with all vendors; determined planning-level budget, footprint

2.

City began visiting MBR facilities using range of equipment

3.

Preselection

–

Developed preselection

process; implemented at end of Facility Planning
