About this file
This document is an email correspondence between engineers at Kimley-Horn and Andreyev Engineering regarding the Ocala Water Treatment Plant No. 2 (WTP-2) project, specifically discussing modifications to ground storage tank (GST) design. The original design of (1) 4.0 MG and (2) 2.0 MG finished water tanks has been updated to (3) 3.0 MG finished water tanks, each with a 120-foot diameter and 35 feet 6 inches liquid depth. The tanks will maintain the same finished floor elevation of 124 feet and bearing capacity of 2,300 psf. Andreyev Engineering confirmed that the boring locations remain consistent with the previous configuration and that the calculated angular distortions of tank bottoms are acceptable.
The attached site plan illustrates the proposed tank locations, including three ground storage tanks (GST No. 1, 2, and 3), an existing well, a proposed high service pump station room, and an electrical building. The geotechnical engineering firm emphasizes the importance of following the foundation recommendations from their geotechnical report. The communication suggests ongoing collaborative design refinement between the engineering teams to ensure the structural integrity and feasibility of the water treatment plant expansion project.

Dear Savannah, The boring locations for the proposed new tanks are shown in the attached figure. The borings cover the proposed tank locations as before.
We understand the applied bearing pressure will remain the same as before at 2,300 psf. With the changed dimensions of the tanks, the calculated angular distortions of the tank bottoms are below d/l of 1/300 and thus acceptable.
We however would like to re-emphasize the need for following the details of the foundation recommendations in the geotechnical report.
Thanks.
Shawkat

Dr. Ali, We have had to make some changes to the Ocala WTP-2 design. We previously had (1) 4.0 MG and (2) 2.0 MG Finished Water GSTs. We have updated this configuration to be (3) 3.0 MG Finished Water GSTs. Please see the screenshot below for reference. The tanks will be in approximately the same location as the previous configuration. The new tanks will have a 120ft diameter with a liquid depth of 35ft 6in. The finished floor elevation for each tank will remain at 124ft and the bearing capacity will remain at 2,300 psf. Can you please confirm if the change in diameter will a ect your recommended subsurface improvements for these tanks?
