Explanation
1. BACKGROUND:
This legislation authorizes the Director of Public Utilities to enter into a professional engineering services contract with Burgess & Niple, Inc. for purposes of undertaking a study in regards to Sanitary Pump Station Instrumentation and Flow Verification.
Work to be completed under this ordinance shall include but not be limited to the following. A hydraulic pumping capacity field investigation of all pumps at the 25 pump stations maintained by the City Of Columbus, Sewer Maintenance Operations Center (SMOC). Each pump shall be evaluated based on in place testing of pump pressures and pumping rates. Compare and evaluate measured parameters to "as built" or "as designed" (also known as original manufacturer's pump curves) parameters. The degree of investigation or testing at each station should be tailored to the complexity and size of the pump station being evaluated. A summary of all field testing results will be relayed to the City. Based on the measured parameters a prioritized list of all pumps will show predictions for scheduled maintenance rebuilding or replacement design points for capital budgeting purposes. The engineering services firm will investigate, recommend, and prepare cost estimates for each station where installation of flow meters, other electrical measurement devices, or sensors would enhance system knowledge to SMOC thru the existing SCADA system.
