This is a sole source letter from Parkson Corporation dated April 17, 2026, confirming the company's exclusive provider status for the Greenwood Lakes Water Reclamation Facility (WRF) located in Lake Mary, Florida. The letter establishes that Parkson Corporation is the sole source provider for parts, service, and repairs for the Dynasand Continuous Backwash filter system, which is the subject product for the Rehabilitation of Sand Filter Beds project at Greenwood Lakes WRF. As the original manufacturer and supplier of the Dynasand filtration system, Parkson Corporation is identified as the only authorized source for original equipment manufacturer (OEM) replacement parts and related services.

The letter serves as official documentation supporting a sole source procurement justification for the filtration system replacement project. By confirming Parkson's exclusive provider status, the document establishes the basis for a non-competitive procurement approach for both the equipment and any associated parts and services required for the project. Contact information is provided for inquiries, with Marty Unger identified as the technical point of contact at Parkson Corporation.
