4610--Engineering Request - SPS REVERSE OSMOSIS | 538-26-3-6064-0049 (VA-26-00079545) - VAMC Chillicothe

The purpose of this amendment is to post questions received and provide the facilities responses. The response date and time remain unchanged. Are the 0.2 Micron Filter Cartridges the ones that are for the tank vent filter we would be providing? Or is this for an existing endotoxin filter housing the facility has? 0.2 Micron Filter Cartridges are for bacterial removal from water and to be compatible with housing provided under CLIN 0003. Tank vent cartridges are maintained separately and not within scope. What flow rates do the 60-gallon and 160-gallon storage tank loop return need to handle? Specifically, when sizing the loop return flow meter we need to ensure it can handle the pump demand. I would assume 20 GPM and 40 GPM based on the UV assembly? Return is being constrained via 3gpm flow control device. Pumps are pressure sensing variable flow rate. Both flow control and pumps are not within scope of the solicitation. UV sized for peak demand. Are there existing pumps within the facility that they are keeping? I do not see a distribution pump mentioned in this bid. Pumps are not within scope. Do you have a list of existing equipment that is being kept for both systems? No What are the distribution loop sizes, loop material and loop length are they existing or is this a new loop? Modifying existing loop. Mixed materials, CPVC and Polypropylene. Loop is approximately 240 LF with mixed sizes of 1 and 1-1/2
