500_Gallon_Round_Fiberglass_Tank_Reference_0001.docx

This file is a product specification document for a 500-gallon round fiberglass tank designed for fish transport operations. The tank features a 6-foot diameter with 30-inch height (actual capacity of 529 gallons) and is constructed with 2-inch wall insulated fiberglass. Key specifications include an 8-inch discharge pipe equipped with a knife gate valve, recirculating lines with threaded 2-inch fittings, and an airstone mounted internally with a supply line exit through the tank top. The tank design incorporates a clamshell half-opening with stainless steel piano hinge for access, two stainless steel tank clamps, an integrated tank handle, an integrated tank lid support, and a flow meter mounting platform.

This tank specification directly supports the Department of the Interior Fish and Wildlife Service's Solicitation 140FS126Q0046 for a CA-SF Bay-Delta Fish and Larval Transport Trailer. The specification is a reference design for the 500-gallon fiberglass fish hauling tank that will be mounted securely onto a DOT-compliant 14-foot aluminum trailer to create a fully integrated transport system. The completed unit is intended to support fish transport operations, specifically including delta smelt supplementation activities. The document includes multiple reference images illustrating the tank design and configuration.
