ATLANTIC OCEAN SOUTH LAKE WORTH INLET Updrift Pumping plant Down drift. /Middle Ground ShooT LAKE WORTH Intercostal Waterway SCALE 200 0 600 I—I—I 1 1 FIGURE 132-SOUTH LAKE WORTH INLET BYPASSING PLANT 4-09• The pumping plant consisted essentially of an 8- inch suction line, a 6-inch 65 Diesel-driven centrifugal pump, and jU^out 1,200 feet of 6-inch discharge line. The installation had a capacity of about 55 cubic yards an hour and averaged -(+8,000 cubic yards a year during U years of operation. The normal rate of littoral drift during that same period was on the order of 225,000 cubic yards a year. At the end of 5 years the beach was restored for a distance of over a mile down- coast. 4-10. During the 3-year period, 1942-1945,- pumping was discontinued with the result that severe erosion of the beaches south of the inlet again occurred. Accordingly, in 1'9455 the plant was again placed in operation. In an attempt to reduce shoaling in the entrance channel, the size of the installation was increased to a lO-inch suction line, 8-inch pump with 275 Diesel motor, and 8-inch discharge line. Observa- tions indicate that a larger pump is reouired and the installation of a 12-inch pump and discharge line is under consideration. 198.
