The New Intake Structure consists of a rake house which is split into two separate trash racks between the east and west side which are the primary defense against large obstructions and foreign objects entering the intake system.   MTI fabricated, furnished and installed a temporary screen in the east side location until the permanent replacement could be procured and installed.   The existing fiberglass, angles and bracing was replaced with matching steel products to provide extra strength and stainless steel hardware was used to prevent corrosion.  All steel angle bracing and new rakes received a marine coating to withstand the corrosive nature of the brackish water.

The debris filled the shafts so it was flush with the invert of the pipe and not functional. Large debris materials required the use of a small crane to lift it to the surface.  Remaining smaller organic debris was loaded into 50 gallon barrels and pulled to the surface by the crane. The slurry and silt left over was pumped into a Geotextile fabric bag at the surface and sediment was separated from the water which allowed the clean water to return to the source.

The motor, reducer and clutch were all replaced in Traveling Screen #3.

Splash Zone repairs were made to concrete spalls located inside concrete structures identified within the Condenser Water System.   The divers cleaned the spall and surrounding area, hand mixed the two-part epoxy and applied it to the surface area of the concrete structure. This product can be applied, troweled out by hand and smoothed in a submerged setting.
