Attachment B Water Tank Specifications 1.pdf

This is an as-built technical drawing for a 500,000 gallon water reservoir project located in Sanford, Florida, prepared by Andreyev Engineering as the consulting engineer. The drawing depicts a circular underground storage tank with a 70'0" inside diameter and 17'4" side water depth, designed to Department of Veterans Affairs specifications at a VA medical center facility. The project includes detailed cross-sectional and plan views showing all structural, mechanical, and operational components.

The reservoir design incorporates precast concrete overflows, multiple valve systems (6" check valve, 6" high level valve, 4" gate valve, and 8" dome pipe connections), interior and exterior fiberglass ladders with safety railings, an aluminum handrail enclosure, access hatches with fiberglass covers, and provisions for a 12" diameter drain pipe. Materials specifications include concrete with Type I/III cement, 3/4" aggregate, 5.5% maximum air content, and a 4-inch soft broom finish; reinforcing steel meeting ASTM A615 Grade 60; and prestressing wire meeting ASTM A821-93. Additional features include a stainless steel wall manhole with field coats, 50-foot fiberglass ventilators, a dome probe curb for electronic level transducers, and 200 square inch precast overflows. The as-built drawing was revised on 02/01/06 with subsequent revisions to the pipe inlet configuration (06/07/06) and includes notes detailing site clearing, equipment storage provisions, and water curing requirements during construction.
