WEBER COUNTY REQUEST FOR PROPOSALS (RFP)

FEASIBILITY STUDY: OGDEN VALLEY SEWER CONNECTION TO CENTRAL WEBER SEWER

IMPROVEMENT DISTRICT | SOLICITATION # 25-301

1. INTRODUCTION

Weber County (“the County”) is requesting proposals from qualified engineering firms (“Proposers”) to perform a

Feasibility Study evaluating the potential for a wastewater conveyance system connecting the Ogden Valley area to the Central Weber Sewer Improvement District (the District). The purpose of this study is to determine the technical, environmental, financial, and logistical feasibility of conveying wastewater from the Ogden Valley across the Wasatch

Mountains to the District’s collection and treatment system.

2. BACKGROUND

The Central Weber Sewer Improvement District currently provides wastewater treatment services to the majority of

Weber County through wholesale agreements with municipalities, Weber County, and one local collection district.

However, the Ogden Valley—including areas near Pineview Reservoir—is not currently served by the District due to geographic separation created by the Wasatch Mountains.

The Ogden Valley relies on onsite septic systems and limited-capacity local sewer districts, including:

- Powder Mountain Water & Sewer Improvement District

- Nordic Valley Sewer Improvement District

- Wolf Creek Water and Sewer Improvement District

Given the limited future capacity of these systems and increasing development pressures, the County is evaluating long-term solutions to ensure wastewater treatment is protective of public health and water quality, especially for

Pineview Reservoir, a Category 1 water under Utah Administrative Code R317-2-3.2.

One potential solution is to convey wastewater from the Ogden Valley to the District’s system, where it would be treated and discharged downstream of Category 1 waters. This concept presents significant technical and environmental challenges due to terrain, distance, and infrastructure needs. A feasibility study is required to evaluate potential routes, impacts, costs, environmental risks, right-of-way (ROW) needs, and implementation strategies.

3. SCOPE OF WORK

The selected firm will conduct a comprehensive feasibility study addressing the following tasks:

Task 1 – Data Collection and Review

Compile existing data on land use, wastewater flow projections, and population trends for the Ogden Valley. Review wastewater conveyance systems in similar mountainous or protected watershed environments. Review District data on treatment and conveyance capacities, including the Central Weber Master Plan (2023). Identify data gaps and reference projects applicable to local constraints.

Task 2 – Conveyance Feasibility Analysis

Identify potential routing options, hydraulic profiles, and required lift station locations. Evaluate technological, geotechnical, operational, environmental, and easement challenges for each alternative. Identify design standards and best practices for mountainous wastewater conveyance systems. Determine potential permits, environmental requirements, and easement constraints (including Forest Service or environmentally sensitive lands). Include a preliminary right-of-way budget estimating anticipated acquisition and easement costs along proposed routes.

Task 3 – Impacts to District’s System

Estimate projected wastewater flows and loadings from Ogden Valley. Evaluate the hydraulic and treatment capacity of the District’s facilities to accept additional flow. Assess impacts to the District’s Capital Improvement Plan (CIP) and identify any necessary system upgrades.

Task 4 – Feasibility Summary and Recommendations

Provide a comparative summary of alternatives, identifying the most technically and financially viable conveyance options. Summarize major risks, environmental considerations, ROW constraints, and recommended next steps.

Deliver a Final Feasibility Report and presentation to Weber County and the District.

4. PROPOSAL SUBMISSION REQUIREMENTS
