These are engineering design drawings prepared by The CROM Corporation for a 2,000,000-gallon water reservoir project for the Siesta Key Utilities Authority in Siesta Key, Florida. The five-sheet technical drawing set provides detailed specifications for a circular prestressed concrete water storage tank, including comprehensive technical details on tank components such as the dome, wall sections, ventilators, overflow outlets, discharge lines, influent lines, and various pipe and structural embedments. The drawings specify precise construction requirements including concrete strength specifications, prestress wire details, shotcrete application methods, reinforcing steel specifications, and specific installation instructions for various tank elements.

The technical drawings indicate a sophisticated water storage tank design with multiple technical considerations, including specific material requirements (Type I cement, prestress wire meeting ASTM specifications), concrete and shotcrete strength specifications (fc of 4000 psi at 28 days), and detailed construction notes for the general contractor. The project appears to be engineered for the Siesta Key Utilities Authority, with design work completed by Bennett & Bishop, consulting engineers and surveyors from Sarasota, Florida. The drawings are dated July 1973 and include precise technical specifications for wall thickness, wire reinforcement, coating processes, and structural integrity considerations for a complex water storage infrastructure project.
