Water Works is the only provider of drinking water to the residents of Terrebonne Parish. We know how important water is, and we want to ensure the water that is delivered to your home is safe and clean.
80% of our raw water supply (approximately 4 billion gallons per year) comes from Bayou Lafourche. The remaining 20% (approximately 1 billion gallons per year) comes from the Gulf Intracoastal Waterway and the Bayou Black Reservoir.
The Intracoastal can no longer be considered a reliable source of fresh water. Every year brings increased salinity levels above 250ppm. At present there are more than 100 days/year of greater than 250ppm.
Terrebonne Parish currently buys about 80% of its raw water supply from the Bayou Lafourche Fresh Water District (BLFWD)
