Culvert shift leads to permit compliance for treatment plant

New cast-in-place concrete structures and relocation of existing precast box culvert helped League City, Texas, extend the Dallas Salmon Wastewater Treatment Plant effluent line with an eye to Texas Commission on Environmental Quality permit compliance.

The Dallas Salmon Wastewater Treatment Plant effluent line was rerouted to meet Texas Commission on Environmental Quality copper and zinc discharge limits. The project garnered Jones|Carter the American Public Works Association, Texas Chapter’s 2019 Environmental Project of the Year Award.

A plan by Bellaire, Texas engineer Jones|Carter to bring the effluent line outfall farther down Clear Creek would enable the city to meet copper and zinc discharge limits. More than half way through design, engineers realized that shifting 1,500 feet of 9- x 6-ft. and 8- x 5-ft. box culvert would interfere with North Kansas Avenue, reconstruction of which was a few years off on the League City capital improvement schedule. The city deemed appropriate the combining of Dallas Salmon plant work and road reconstruction, which required a large cast-in-place culvert and existing roadway repaving.

The new outfall line prompted utility relocation and overland drainage path diversion. Effluent line extension was completed and certified one month ahead of a TCEQ deadline. Joining Jones|Carter on the project were Ardurra Group, Terracon Consultants, EcoLogic Inc., C.N. Koehl Urban Forestry and SER Construction Partners.
