Name of Project:
Caloosahatchee Reservoir, Florida

The Lane Construction Corporation (U.S. subsidiary of the Salini Impregilo Group)


Total value:
$524 million

Lane of Salini Impregilo Group has won a $524-million contract to build the Caloosahatchee (C43) West Basin Storage Reservoir in southern Florida

Commissioned by the South Florida Water Management District as part of the Comprehensive Everglades Restoration Plan, the contract is to reduce harmful discharges into the Caloosahatchee Estuary in Hendry County by 2024.

It includes the construction of an earth-fill dam with a perimetre of about 16.3 miles (26.2 kilometres) and a separator dam of 2.8 miles (4.5 kilometres) in length. The reservoir will encompass about 10,000 acres (40.5 square kilometres) and store 170,000 acre-feet (209.7 million cubic metres) of water when full.

When it rains, the reservoir will capture water run-offs contaminated by residential and agricultural developments in the area. During dry periods, it will maintain a desirable minimum flow of fresh water to the estuary, reducing extreme salinity changes.

Perimetre: 16.3 miles (26.2 km)
Dam Length: 2.8 miles (4.5 km)
Surface: 10,000 acres (40.5 Km2)
Storage Capacity: 170,000 acre-feet (209.7 million m3) of water
