PROJECT DESCRIPTION

A. The construction of a water supply and drain system that will connect to the existing Leavenworth National Fish Hatchery (Hatchery) infrastructure and provide required piping for the operation of a partial reuse aquaculture system (PRAS). Demolition of the northern bank of Small Foster Lucas Pond raceways is required to allow for the installation of two (2) circular tank PRAS. Each PRAS is comprised of two (2) 26-foot diameter by 7-foot high dual drain circular tanks, a carbon dioxide (CO2) stripper system, micro-screen drum filter, ultra-violet disinfection equipment, low head oxygenators (LHOs), submersible pumps, pump sump, and
associated support equipment and piping. The solids handing equipment is comprised of
micro-screen drum filters, a radial flow separator, solids pumping station, and construction
of concrete evaporation ponds and associated support equipment and piping. The circular
tank PRAS and solids handling facility will be enclosed in a pre-manufactured metal
building.

B. The installation of new raw water supply piping and ground water piping will be
connected to existing water supplies located just outside (west side) of the existing
hatchery building. Overflow drainpipes (clean effluent from PRAS) will connect to
existing drain manholes. Effluent piping will be routed from the solids handling
equipment to either the existing abatement ponds or to the solids handling evaporation
ponds.
