Request For Proposals Aquifer Storage and Recovery (ASR) Design and Permitting Study

The City of Silverton, Oregon Public Works Department is requesting proposals for engineering design and permitting services for an Aquifer Storage and Recovery (ASR) system, with proposals due July 21, 2026 at 2:00 p.m. The project is funded through a $300,550 grant from the Oregon Business Development Department's Aquifer Recharge Testing Program (Project No. AR2603) under Oregon Laws 2023, Chapter 606.

The scope encompasses advancing a preferred ASR alternative to approximately 30 percent design level to support permitting, budgeting, and future final design and construction. Primary tasks include project management and coordination, data review and site evaluation, pipeline and system integration analysis, permitting and regulatory coordination, cost estimating and implementation planning, and preparation of a final ASR Design and Permitting Study Report. Work must be completed within a 36-month grant performance period from the effective date of the grant agreement.

Qualified consultant teams must demonstrate a minimum of five years of relevant experience in ASR system design, hydrogeologic evaluation of Columbia River Basalt Group aquifers, municipal drinking water system planning, groundwater modeling, and Oregon water rights and UIC permitting experience. The selected consultant must comply with all state grant requirements, including reimbursement-based invoicing, audit and records retention standards, and Oregon Public Contracting Code compliance.

Evaluation criteria are weighted as follows: Relevant ASR Experience (25 points), Technical Team (20 points), Project Understanding (15 points), Regulatory Experience (15 points), References (15 points), and Schedule/Availability (10 points). The City will evaluate submissions and shortlist the top three firms for potential negotiation, with final award approval by City Council. Proposals must be submitted in PDF format via email to Jerry Nelzen at jnelzen@silverton.or.us and must not exceed 20 pages excluding the cover page. All work products become property of the City upon completion.
