Proposed Location of PUD Return Line Control Valves <br /> Old #5 Line Cross Connect Improvements: Design and construction efforts for the <br /> old #5 line cross connect improvements will be achieved in conjunction with replacing <br /> the screenhouse valves as described above. The Design-Builder is expected to develop <br /> options to daylight the potential cross connection point between the screenhouse intake <br /> lines and the Old #5 line, and also review options to address the removal of the <br /> stagnant water in the Old #5 line should the connection between ISBV5 and ISBV6 be <br /> needed. The Design-Builder shall then submit the options to the City and Washington <br /> State Department of Health for review and approval prior to commencing full design and <br /> construction activities. Improvement options are intended to include provisions for rapid <br /> connection of pipe(s) between ISBV5 and ISBV6 in emergency situations. Any <br /> underground infrastructure related the old #5 line cross connect improvements is <br /> intended to be housed in a seismically stabilized containment vault. Flow to the <br /> flocculation basin must be maintained during this work. It's anticipated the work will be <br /> performed through bypassing the valves along with short shutdowns of the inlet pipes. <br /> Flocculation Basin Improvements: The flocculation basin improvements are intended <br /> to include mixer replacement, structure coating/sealing, installation of a davit crane, and <br /> Page 4 of 16 <br />
