Staff recommends the City Council award a contract for W.O. 22-01, Schedules 1 & 2: Water and Sanitary Sewer Main Replacement, to DOWL in the amount of $1,153,670.00

The City replaces and upgrades its water and sanitary sewer utilities as part of an annual maintenance program.  This project will replace approximately 9,700 feet of existing water main and 11,300 feet of existing sanitary sewer. Water mains being replaced were selected based on several criteria including age, break history, lead joint pipe, lead services, and undersized water mains.  This project will replace water mains that are 58 to 106 years old, remove and replace approximately 151 lead services, upsize 4-inch and 6-inch water mains to 8-inch size, resulting in the reduction of maintenance costs from water main breaks.  The sewer mains being replaced with this project were selected based on age, video inspection condition assessment, root intrusion history, and sewer back up history.  This project will replace sanitary sewer mains that are 100 to 120 years old made of clay tile.  These sewer mains exhibit broken and cracked pipe and many sections need yearly root intrusion removal and maintenance.

DOWL was selected for the project using the proposal process.  Two other proposals were received from Sanderson Stewart and Morrison-Maierle.  The consultant selection was based on Project Team and Availability; Project Approach; and Firm Qualifications and Experience as related to the project needs.

City Council may:

• Approve awarding the Professional Engineering Services Contract to DOWL, or;
• Not Approve awarding the engineering contract to DOWL. If the project is not awarded, the City's water mains and sanitary sewer collection systems in these areas will continue to be unreliable and may experience ongoing maintenance problems and expenses.

The project was budgeted in FY22 using water and wastewater funds.  The amounts budgeted are $3,400,000.00 for water and $4,400,000.00 for sewer.  The remaining budget will be used for construction.
