In a recent e-news email, the National Corrugated Steel Pipe Association covers the Breedlove Land Planning design of an 100,000+ gallon cistern for the University of Georgia Special Collections Library:
Engineer of record, Breedlove Land Planning Inc., designed three large tanks, 37 feet, 50 feet and 58 feet in length, to be fabricated from 144 inch diameter, 10 gauge CSP. The cistern’s Aluminized Steel Type 2 coating offers a 100 year service life.
Breedlove specified that these CSP tanks be fabricated as single pieces with bulkheads welded to each end, on the interior and exterior for water tightness. The lockseams were sealed during the manufacturing process to eliminate leakage. Lockseams may be sealed by a full seam weld or by the addition of a gasket during the manufacturing process.
The cistern collects treated stormwater runoff from the site and mechanical equipment condensates for re-use as irrigation water for plant establishment. Once the proposed drought tolerant plants are established, the cistern’s water will then be sent for reuse at a downstream campus utility plant. In both cases, the cistern will provide a significant reduction in potable water use and will help earn the new library LEED certification.
