A Twin Tank Water Softener System, including associated plumbing supplies, labor, installation, and delivery, is needed for the Phoenix Indian Medical Center. The existing brine tank has reached the end of its service life due to age-related deterioration, causing structural weakness, sludge accumulation, and inefficient regeneration. Replacement is required to maintain consistent water quality, protect critical hospital equipment, and support uninterrupted patient care. Performance of services will be at the Phoenix Indian Medical Center. No budget amounts or non-bid timelines are specified in the description.
