<br />A/ternative No. 3- Repair the Out/et Conduits On/y
<br />The third alternative explored was to replace the steel lined section of the outlet conduits while leaving
<br />the upstream outlet gates in their current condition. In this alternative FRICO wouid clean the existing 44
<br />inch steel lined sections and install a 40 inch slip line steel section of conduit inside of the existing 44 inch
<br />sections. This work would be done without draining the reservoir. Without the reservoir drained, the
<br />work would be done with hydrostatic pressures on the outlet works and limited fresh air supply into the
<br />work space. The existing leaking upstream gates would also result in needing to complete this work in a
<br />wet environment. The 40 inch section would need to be assembled outside of the outlet works and
<br />installed as a completed system as welding in the interior of the pipe is not practical given air and water
<br />conditions. As a result FRICO would not be able to remove the existing 44 inch pipes but would instead
<br />proceed with this, less desirable fix. The annular space between the existing 44 inch line and the new 40
<br />inch steel sleeves would be grouted and the upstream and downstream extents of the new lined section
<br />would be tied into the cast iron pipe.
