Project Name:   Weeks Island DOE Water Line
Project Location Iberia Parish, LA
Client:   Lydia Water Corporation
Estimated Const. Cost: $717,000
Funding Sources: DOE-Federal Strategic Oil Reserve

PEC was retained by the Lydia Water Corporation to design and administer construction of a 5 mile long, 6-inch water main to service a DOE salt dome petroleum storage site on Week’s Island adjacent to Week’s Bay in Iberia Parish.  The firm was responsible for coordinating all environmental,  topographic and hydrographic surveying and related geotechnical investigations necessary for the water main’s design and construction.  The line was constructed from the Lydia water treatment plant and laid in the ROW along State highway in adjacent marsh terrain till it entry into the DOE Petroleum Salt dome storage site. The pipeline crossed numerous bayou’s and canals. The pipeline was polyethylene, was laid in a submerged trench, and was weighed appropriately to counter buoyancy of the water environment.  The water main was designed to avoid various utilities, pipelines and construction obstacles.  The firm was responsible for coordination with multiple agencies and DOE officials and was also responsible for obtaining all coastal permits, COE, DHH, and LA DEQ and La DOTD clearances and related permitting.
