This is a service / maintenance or supply contract in Banning, California. Contact the soliciting agency for additional information.

The City of Banning ("City") is soliciting request for proposals (RFP) from qualified engineering consultants to provide "On-Call" hydraulic feasibility studies on a 1-year on-call services contract (with the possibility of two additional one year extensions) for water, wastewater ('sewer') and recycled water, including but not limited to, review of the existing hydraulic models and their scenario(s) assumptions, feasibility/concept plan studies and recommendations; overall system evaluation of capacity and efficiency; hydraulic model calibration and adjustment; and such other services as maybe required by the City for private developments and/or capital improvements. The City of Banning is located in Riverside County along Interstate 10 between the Inland Empire and the Coachella Valley in the San Gorgonio Pass. As of 2016, the City provides municipal water and sewer service to a population of approximately 32,000 residents through approximately 11,000 water and 10,500 sewer service connections. The City also provides water to the Banning Heights Mutual Water Company and High Valleys Water District. The City's potable water supply is primarily served by groundwater via 21 potable wells plus three co-owned wells from five basins: Beaumont Basin, Banning Basin, Cabazon Storage Unit, Banning Bench Storage Unit, and Banning Water Canyon Basin. The City also purchases imported water from the San Gorgonio Pass Water Agency (SGPWA), which is discharged to the BCVWD recharge facility and stored in the Beaumont Basin. Additionally, the City recharges the Banning Canyon Storage Unit with water delivered from the Whitewater River via a flume system. The average annual water supply between 2012 and 2014 was 8,595 afy, which equates to an average day demand (ADD) of 7.7 mgd. The average maximum month demand (MMD) for this same time period was 10.1 mgd, while the maximum day demand (MDD) was calculated to be approximately 13.3 mgd. Based on historical records, the average annual flow at the City's wastewater treatment plant (WWTP) was estimated to be roughly 2.02 mgd for years 2011 through 2016. The existing average dry weather flow (ADWF) is approximately 2.08 mgd for years 2011 through 2016. The City's 5-year average per capita wastewater generation was estimated at 73 gallons per capita per day (gpcd). The City currently serves one customer (Sun Lakes Development Golf Course) with non-potable water from Well M7. Based on average production data for years 2012 through 2014, the average annual demand for Sun Lakes Development Golf Course is 850 afy (or 0.8 mgd). Once City's WWTP is upgraded within the next 3 years, a tertiary treated title-22 recycled water will be available to Sun Lakes and other current developments which are currently installing "purple pipe" to able to convert landscaping/green-belts from non-potable to recycled water. During the 2018 Integrated Master Plan (IMP) preparation, three (3) separate hydraulic models were utilized for the analysis of the potable water, sewer collection, and recycled water systems. Additional details regarding the water and recycled water model updates, as well as the wastewater collection model development and calibration, are provided in Chapter 4 of the IMP (attached). The City is a full-service city in that its Public Works Department performs all engineering duties. These duties include management of the City's Capital Improvement Program (CIP), design and construction management of CIP projects, design review and analysis of proposed developments, maintenance of the City's record drawings, hydraulic model and GIS system. The IMP considered water improvement projects that were ongoing at the time of IMP preparation, or soon to be undertaken. Most of those in-progress projects have now been completed and are incorporated into the hydraulic model. However, there are a number of sizeable residential developments that are either in construction or have been completed and have not yet been incorporated into the water, sewer and recycled water model. Often development does not occur in accordance with the anticipated growth pattern used as the basis for the IMP. As a result, there arises a need to perform Hydraulic Feasibility Studies to confirm that the existing water, sewer and recycled water systems are adequate to serve the demand of the proposed development and to determine any necessary upgrades to the system. (The scope of this Feasibility Study includes off-site i.e., current City owned and/or new development utility/facility installation to be dedicated to the City only; the on-site i.e., single or multi-family dwellings, commercial/industrial building(s) hydraulic analysis is the responsibility of the developer). For each of these tasks, the City wishes to have hourly rates for each classification of consultant's staffing that outlines the expected distribution of duties (i.e. report preparation, hydraulic modeling, exhibits/maps, review, secretarial, etc.) Question Deadline 09/10/2025 at 4:00 PM PT Questions will be received at online. If applicable, Company and/or its key personnel, shall hold an appropriate license for the Company's discipline and the Services on the date the Proposal is submitted. The method of Contractor Selection has not been Determined at this time.
