About this file
This is a Pipe Schedule exhibit prepared by Carollo Engineers, Inc. for Collier County's South County Regional Water Treatment Plant (SCRWTP) Lime Softening Improvements - Blend Tank project (Bid No. 26-8683). The document specifies materials, dimensions, pressure ratings, testing methods, and installation requirements for all piping systems associated with the blend tank construction. Piping materials include polyvinyl chloride (PVC) for drain lines ranging from 0.5 to 12 inches, chlorinated polyvinyl chloride (CPVC) Schedule 80 for chemical injection systems (chlorine solution, ammonia, sodium hydroxide, and corrosion inhibitor) in sizes from 0.5 to 4 inches, and ductile iron pipe (DIP) rated at 150 pounds per square inch for process water lines including 42-inch blended finished water and 36-inch filter effluent lines. All chemical injection piping requires double-wall containment with leak detection. Joints and fittings specifications vary by application, with solvent-welded connections for plastic piping and restrained mechanical joints for ductile iron piping. Test pressures range from gravity method testing for drain systems to high-head testing at 125 pounds per square inch for pressurized water lines. The schedule includes coating and lining requirements, with cement mortar lining and polyethylene encasement specified for ductile iron piping carrying blended finished water and filter effluent to ensure water quality protection and corrosion resistance.
The document was digitally signed and sealed on June 29, 2026, by Anthony Ryan Horvat, P.E., and serves as Addendum 4 to the specification set for the blend tank construction. This pipe schedule is referenced in Section 40_05_00.01 (Common Work Results for General Piping) and cross-references detailed specifications in Section 40_05_31.01 for plastic piping and Section 40_05_19.01 for ductile iron piping. The schedule establishes standards for underground and aboveground piping installations, differentiating between process water, chemical injection, and drain systems to ensure compliance with applicable codes and the project's operational requirements while maintaining the facility's function as the county's sole drinking water source during construction.
