The Comprehensive Everglades Restoration Plan (CERP) was authorized by Congress in 2000 as a plan to “restore, preserve, and protect the south
Florida ecosystem while providing for other water-related
needs of the region, including water supply and flood protection.” The $10.5 billion, 35+ year multi-agency project is the
largest hydrologic restoration project ever undertaken in the
The Picayune Strand Restoration Project is a component of CERP. Wetlands will be restored in Picayune Strand
(Southern Golden Gate Estates) and in adjacent public lands
by reducing over-drainage while restoring a natural and
beneficial sheetflow of water to the Ten Thousand Islands
National Wildlife Refuge. The project includes 83 miles of
canal plugs, 227 miles of road removal, and the addition of
three pump stations and spreader swales to aid in rehydra-tion of the wetlands.
In partnership with the South Florida Water Management
District (SFWMD), the U.S. Army Corps of Engineers (USACE)
will operate the three large pump stations, which will transport water gathered from canals to previously drained wetlands and help maintain current levels of flood protection.
ABOUT THE PUMP STATIONS
The Picayune Strand project includes the construction of
three pump stations: Merritt, Faka Union and Miller Pump
The Merritt Pump Station facility includes a spreader canal
and tie-back levee. It has two 75-cubic-feet-per-second (cfs)
electrical pumps and four 220-cfs diesel pumps for a total capacity of 1,030 cfs. The maximum design flow for flood protection is 880 cfs using the four high-flow pumps.
Now operational, the Merritt Pump Station transports water from the Merritt Canal into a spreader basin for release to
the downstream restoration area. Part of the project also included plugging 13. 5 miles of canals to block water flow and
the removal/degrading of 95 miles of roads and tram lines.
The Merritt Pump Station was completed in 2014.
NEGATIVE SIDE WATERPROOFING INSIDE THE PUMP
Soon after completion, hydrostatic pressure caused the
Merritt Pump Station pump rooms, which are located 20 feet
below grade, to fill with up to eight feet of water.
To remedy the problem, SFWMD recommended a Xypex
