RE:	June 19, 2007 City Commission Agenda – PS_ 25 (East Hills Business Park Pump Station) Upgrade -  Advertise RFP

Please include the following item on the City Commission agenda for consideration at the June 19, 2007 meeting:

Authorize advertisement of a Request for Proposals (RFP) for engineering and construction inspection services for the design of modifications to Pump Station 25 (East Hills Business Park).

Background Information: The 2003 Wastewater Master Plan identified improvements required to Pump Station 25 (PS25) to provide expanded sanitary sewer capacity to the areas east of O’Connell Road and north and south of K10/23rd Street including the East Hills Business Park and the former Farmland property (see attached map). These improvements include expanding the firm pumping capacity of PS25 from 0.97 MGD to 5.95 MGD and the construction of a parallel 8” forcemain. The improvements also provide for reliability and safety enhancements to the pump station. The improvements are included in the Department of Utilities Capital Improvements Plan and are scheduled to be completed in 2008 & 2009.

The improvements to PS25 will work in conjunction with a new pump station (PS49), currently under design as part of a County benefit district to provide sanitary sewer service to current and future areas of the City southeast of 23rd Street and O’Connell Road. PS49 will initially collect flows and pump them north to PS25 which discharges to the existing Kaw Wastewater Treatment Plant. The recommend timing of PS25’s improvements and expansion have been confirmed and coincide with development and flow forecasts for the PS49 service area. 

Preliminary Schedule:  The estimated schedule will be revised to include the opinion of the selected consultant.
