Explanation

1. BACKGROUND: This legislation authorizes the Director of Public Utilities to enter into an agreement with CH2M Hill, Inc., in the amount of $10,432,936.00, for professional engineering services for the Dublin Road Water Plant (DRWP) Treatment Capacity Increase - Detailed Design Project.

Modifications to the Dublin Road Water Plant (DRWP) treatment process are necessary to increase plant capacity from 65 million gallons per day (MGD) to 90 MGD as recommended by the Water Beyond 2000 Phase III report and to comply with new rules promulgated by the Ohio Environmental Protection Agency (OEPA) set forth in the Stage 2 Disinfection By-Product Rule and the Long Term 2 Enhanced Surface Water Treatment Rule. This contract is for professional services for detailed design of treatment improvements selected from several pilot studies conducted in a previous contract (Project No. 690428, Contract No. 1009) at the DRWP. The new improvements will give the City the capability to remain in compliance with OEPA rules for drinking water and meet future water demand projections.

The professional engineering services will be completed in multiple phases:
1). Preliminary Design
2). Detailed Design (future planned contract modification)
3). Services During Construction (future planned contract modification)

Preliminary Design: Work under this phase will include assisting in the alternatives analysis of three pilot treatment layout options, including the evaluation of membrane processes (including Reverse Osmosis and Ultrafiltration), high rate clarification (Aqua DAF, Actiflo and Accelator) and residuals handling and disposal (Densadeg). Elements of this phase of work will include various meetings and workshops, value engineering, survey and mapping of the project site, geotechnical investigations, preliminary design drawings, and a Preliminary Design Report (PDR).

Detailed Design: Work under this future phase will include the preparation of Det...
