Site work for a water / sewer project in Mesa, Arizona. Conceptual plans call for site work for a water / sewer project.

The City of Mesa is seeking a qualified consulting firm or team to provide complete design services for the following projects as a single award: CP0618NS03 Rittenhouse Sewer Phase 2/CP0618NS08 Pecos Road Relief Sewer/CP0805CAP Unity to Old Pecos Road 24-inch Sewer. All qualified firms that are interested in providing these services to the City of Mesa are invited to submit their Statement of Qualifications (SOQ). All SOQs must comply with the requirements specified in this Request for Qualifications (RFQ). SECTION I - PROJECT DESCRIPTION The proposed improvements are as follows: Pecos Road Relief Sewer Installation of a relief sewer parallel to the existing sewer in Pecos Road from Ellsworth to Power Road. The new relief sewer will connect to the existing 18-inch sewer north of the MH29406 at the Pecos/Willis Road intersection. The new relief sewer is planned to be routed on the north side of the existing sewer in Pecos Road, with periodic tie-overs from the existing sewer to the new sewer to shed flow load on the existing sewer. The proposed sewer will intercept any sewer services or sewer mains flowing from the north. The relief sewer is planned to be 18-inch diameter from Ellsworth to Hawes, 21-inch from Hawes to Sossaman, and 27-inch from Sossaman to Power in accordance with the 2018 Wastewater Master Plan Update. The relief sewer is to connect to an existing dry sewer stub on MH31202 north of the Pecos/Power Road intersection. Rittenhouse Sewer Phase 2 Installation of a new 36-inch diameter sewer continuing along Pecos Road from the existing, dry sewer southwest of MH31198 that was installed as part of City Project Number 09-005-001 to the East Mesa Intercept (EMI). Rehabilitation or replacement of an existing metering station (MS-9) that measures EMI flows. Installation of metering facilities for the new relief sewer. In City Project Number 09-005-001, an alignment from Power Road to the connection to the EMI, located on the west side of the East Maricopa Floodway was taken past 90% design, but only a portion of it was built. This project will evaluate the previously proposed alignment to see if it is still valid or if an alternative alignment is required. The alignment shown in the old project will require the relocation of metering station MS-9 which measures the EMI flows. An alternative alignment may be able to utilize the existing MS-9 equipment. The flows from the new relief sewer must be measured by a metering station as it is used to calculate billing for the Greenfield Water Reclamation Plant. Please note that City Project number OT0115G001 recommended extensive rehabilitation of the existing MS-9 metering station - in this project, either a new station will be built or the existing station will be refurbished.
