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 h.p. 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 h.p. 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.
