Title
Resolution to Approve Professional Services Agreement with CDM Michigan Inc. for the Lime Feed System Improvements Project ($523,163.00)
Memorandum
This memorandum and resolution request approval of the professional services agreement with CDM Michigan Inc. to provide professional engineering services for design and construction of the Lime Feed System Improvements Project at the water treatment plant (WTP). This project is included in the approved FY08-13 Capital Improvements Plan and was approved by Council as part of the FY08 capital budget process.
This project includes replacing three lime slakers and modifying the associated lime storage bins. The existing lime slakers are in poor condition and were identified during the WTP Facilities Master Plan - 2006 as one of the highest priority capital improvements. The lime slakers are some of the most critical pieces of equipment at the WTP. Without operating slakers, the treatment process is ineffective and the WTP would not be able to meet state drinking water standards. A second critical component to this project is to evaluate and design alternatives to address safety concerns associated with the existing lime bins. The WTP has experienced several lime slides of varying degrees over the past 5 years that have caused minor injury to staff and damaged lime slaking and other equipment in the vicinity. Modifications to the bins will be evaluated to eliminate the occurrence of these events. Finally, this project will evaluate, but not design at this time, the capabilities of the WTP to produce a softer water and/or water with a more consistent level of hardness year round. The public engagement component of the Facilities Master Plan - 2006 indicated an interest by water customers to receive softer water. The Consultant, as part of this project, will continue to explore this desire by water customers and determine the costs and benefits of implementing treatment changes to reduce the hardness in de...
