About this file
This is Addendum No. 3 to a federal contract solicitation for the Hurricane Ridge Water System rehabilitation project, consisting entirely of photographs and related documentation illustrating the existing water system infrastructure and conditions at Hurricane Ridge in Olympic National Park.
The document provides visual documentation of key system components including: the groundwater treatment building with Rosemount flow meter, chlorine solution tanks, and chemical feed pumps; the 100,000-gallon in-ground reinforced concrete water storage reservoir divided into north and south chambers; valve vault infrastructure showing distribution, drain, and overflow piping; new aluminum access hatches installed in 2023; extensive efflorescence and corrosion visible on tank roofing and pipe penetrations; and communications signal boxes containing float control wiring. Additional photographs document obsolete intake dam infrastructure on Idaho Springs, including the upper intake dam (original construction with sand and gravel filtration backfill) and lower intake dam (constructed 1985 with submersible pumps), along with associated pump houses and electrical equipment designated for demolition. The addendum also includes documentation of electrical infrastructure (J-box 321780, transformer 321783, and a 1984 non-PCB transformer serving the obsolete pump house), temporary utility modifications following a May 2023 fire that destroyed the Hurricane Ridge Day Lodge, existing water distribution piping including C900 and asbestos cement pipes, and details of the current water treatment building electrical panel and well pump controls (Franklin 10 HP motor with Cerus Titan P-Series VFD controller). Schematic drawings, as-built construction details, and site maps supplement the photographic record.

Figure 8. Electrical junction box for well pump float control signal wire in valve vault. Note that only one float is wired into the well pump VFD located in the treatment building. This on/off float is connected by the orange wire nuts and is the highest float on the float tree located inside the south chamber.
