When Size Matters Rehabilitating large inverted siphons in Louisiana

The Sabine River Authority (SRA) was created in 1949 to equitably distribute the waters of the Sabine River and its tributaries. As part of this distribution, “We provide surface water to 11 industrial customers, such as Conoco and Louisiana Pigment, for cooling and processing,” says SRA facility manager Mike Carr. This water is conveyed mostly via a 35-mile-long open canal, but where that canal must cross under roadways and railroad tracks the water passes through inverted siphons.
