Water Treatment Plant and Hinkle to

Baldwin Pipeline Valve Replacement Project

Request for Proposals

I.

INTRODUCTION

San Juan Water District (District) is seeking professional proposals from qualified engineering

consulting firms to provide engineering services for Water Treatment Plant and Hinkle to Baldwin

Pipeline Valve Project. The Project is located at the District’s main Corp yard in Granite Bay, CA in

Placer County.

This project consists of preparing ready for construction bid documents for the replacement a 48”

and 60” valve at the District’s water treatment plant, the construction/installation of a new 72”

valve on the Hinkle to Baldwin Pipeline (HTBPL), and internal repairs of a 60” treated water pipeline.

The location and sizes of the three valves are shown in Figure 1 below. Additionally, recognizing

that the large diameter valves have a long lead time, the consultant shall prepare a complete bid

package for the prepurchase of the three valves.

This Request for Proposals (RFP) describes the Project, the required scope of services, project

milestones, Consultant selection process, and the minimum amount of information that must be

included in the proposal. Failure to submit information in accordance with these requirements and

procedures may be cause for disqualification.

II. BACKGROUND

The District is in the beginning phases of evaluating our wholesale transmission mains throughout

the District. The first phase of this project includes the restoration of the District’s Treated Water

Pipeline #1 (TW1) and evaluation of the District’s 72” HTBPL. To facilitate this work, two valves

need to be replaced or one valve installed to allow for proper isolation of the system.

The 60” diameter TW1 Pipeline and the 48” Bypass Pipeline connect at a tee located under the

drive at the Sidney N. Peterson Water Treatment Plant (WTP) (See Figure 1). Both pipelines are

cement-mortar lined and coated steel cylinder pipe conforming to the AWWA C200 specification.

Based on the Shop drawings, the pipe steel cylinder is ¼-in thick, and it is cement-mortar lined and

coated. Most of the pipeline is 45 plus years old and was constructed in 1980. Figure 2 below

shows the configuration of the 60”x48” tee connection.

Figure 2: 60" TW1 & 48" Bypass Pipeline Tee Connection

The TW1 Pipeline was evaluated in 2025. This evaluation concluded that the 48” and 60” butterfly

valves needed to be replaced. See valve observations below. The evaluation also concluded that

spot and joint repairs are needed to the mortar lining within the pipe. A table of the detailed

findings of the evaluation are provided in Exhibit B.

The HTBPL is a 72” reinforced concrete pipe (AWWA 302 RCP) that extends from the District’s

Hinkle Reservoir to Baldwin Reservoir located approximately one half mile to the west. The pipeline

was installed in 1974. As part of a project completed in 2013, a cross was installed to connect the

two primary transmission mains leaving the WTP (See Figure 3). To properly isolate the HTBPL and

maintain service through Hinkle Reservoir, a new 72” valve needs to be installed west of this cross.

The goal of this project is for the selected Consultant to prepare and submit a ready for bid plans

and specification package for construction in summer/fall of 2026. The valve pre-purchase bid

package shall be prepared early in the design process, so that the valves can be ordered promptly.

III. SCOPE OF WORK

Interested consultants are encouraged to develop a scope of work that addresses the District’s

needs and provides value and innovation. Optional tasks recommended by the consulting firm to

enhance the work product should also be included in the proposal and shall be clearly identified as

optional items. Fully describe any exceptions to the anticipated scope as outlined in the RFP.

Identify information needs or work that the consultant expects to be completed by District staff. If

there are no expectations of District staff effort listed for a task, the District will expect the task to

be completed without any District staff time. The consulting firm selected for this Project will be

required to provide the necessary equipment, materials, and labor to complete the following

services.

Task 1 - Project Management

Throughout all tasks, the Consultant shall provide project management activities such as staffing,

subconsultant coordination, budget management, schedule management, and coordination with
