Specifications include, but are not limited to: expand the plant from 24 MGD to 48 MGD. The project scope will include the addition of a new 8 MG buried concrete reservoir and expansion of the processes in the existing plant to meet the new capacity. The original Basis of Design Report (BDR) that covered all phases of the water treatment plant at this site was prepared in 2004 and was supplemented in 2010 and updated post construction in 2019. The supplemented and updated BDR will be made available with the RFQ. All other records related to the SBWTP, including record drawings, design studies, etc., are considered sensitive and protected information will not be available to proposers. The project scope covered by this RFQ will consist of a Preliminary Design Report (PDR) which will build on the BDR to evaluate the current processes, look for opportunities to improve plant efficiencies, evaluate the regional growth impacts on the water demand, review new treatment technologies, and evaluate construction sequencing. This PDR will be used to optimize the scope of the Design to expand facilities at the site to the max design capacity of 48 MGD.
