Description
The City of Spokane issued a Request for Qualifications (RFQu 5479‑21) seeking a qualified engineering/consulting firm to conduct a feasibility and cost‑estimate study for a new deep‑sand wellfield at the existing Well Electric site. The scope requires review of prior studies, recommendation of a second exploratory borehole, design of a high‑rate test well, execution of a multi‑day pumping test with comprehensive water‑quality sampling, hydraulic‑parameter analysis, groundwater‑modeling, and optional conceptual design of a full wellfield layout, including pump and electrical system recommendations. The work is to be completed sequentially, with deliverables including a test‑well prognosis, data‑analysis reports, and, if feasible, conceptual site‑development plans.
• Conduct a second exploratory borehole and high‑rate pumping test to characterize the SVRP deep‑sand aquifer.
• Perform hydraulic‑parameter estimation, groundwater‑modeling, and river‑impact assessment.
• Provide optional conceptual designs for wellfield layout, pump‑station sizing, and electrical specifications.
