Kleinschmidt is working collaboratively with a confidential client to plan and develop a design that integrates the kelt reconditioning facility into the existing Nez Perce Hatchery. Design features included extending the existing water supply system to the reconditioning tanks and adding four 15-foot in diameter and six 20-foot in diameter holding tanks that are each 5 feet high. The tanks are located within a newly designed 60-foot by 150-foot-long building, which includes rooms for an office, electrical room, bathroom, evaluation room, feed storage, chemical room, and general storage. The facility includes high-efficiency lighting and HVAC systems. On-site oxygen tanks are piped to readily supply air-stones in each tank should the normal water supply fail. A formalin treatment system can treat each tank for disease. Tank flow, temperature, and dissolved oxygen are monitored by a supervisory control and data acquisition (SCADA) system to display and log conditions and enunciate alarms readily. We prepared 10, 30, 60, and 90-percent design documents for review, followed by construction bid documents consisting of drawings and technical specifications. All the review sets included a design report and a construction cost opinion for the proposed improvements.

Our experience in hatchery design, intakes, piping, and pumping systems is resulting in the design of a facility that is safe for fish and personnel, efficient to operate and includes a seasonal intake that is readily deployed for use when the existing primary intake is offline for maintenance each year. Using seasonal intake during the construction period avoids in-water work, reduces the need for permits, and saves on construction costs.
