East Side Water Treatment Plant Expansion to 540 MGD – Part B

Completed in 2014 by Oscar Renda Contracting, the East Side Water Treatment Plant Expansion to 540 MGD – Part B project consisted of the construction of clear-wells, deep concrete flumes, and junction structures. Scope of work included, clearing, grading, excavation, pipeline installation, structural concrete placement, equipment installation and final restoration. Construction phasing and coordination with the plant operations is critical due to the existing undersized clear- wells that must remain in operation while constructing around them and then demolition of these facilities and for construction of the remaining clear-wells and deepest flumes. The concrete flumes range in size from 10 foot by 10 foot to 12 foot by 12 foot inside dimensions and are to be constructed at up to 45 feet total depth. The junction structures are equipped with slide gates for flow control and are to be constructed of 48’-6” walls. Sitework to include yard piping, concrete paving and landscaping. The 4 clear-wells are to be constructed of wire-wound pre-stressed concrete. These 15.625-million-gallon storage tanks will be the largest tanks ever constructed by this method in the world, with a total construction cost of 94.77 million and a 3-year construction schedule, this project, along with the upgrades to filtration and distribution pump station will be the largest expansion for Dallas Water Utilities to date. East Side Water Treatment Plant is rated at 540 MGD.
