The Brownsville Public Utilities Board’s Resaca Restoration Project is officially under way after a project launch ceremony March 22, 2013 at Brownsville’s historic Old City Cemetery. This project is necessary because sediment, trash and other debris has built up over the years, impeding water flow in these waterways. The way to return the resacas to their original depth is to dredge them.
The Resaca Restoration Project will be completed in segments with the Cemetery Resaca being the first site dredged in this long-term project. The Cemetery Resaca, BPUB will move on to other Phase I sites, which include the Gladys Porter Zoo resacas. BPUB is currently dredging the Dean Porter Park Resaca and will move to the Resaca Boulevard Resaca.
The dredger itself is a specialized boat with cutters used to help break up the debris and sediment. The dredger then pumps material much like a vacuum, sending it through floating pipes until it winds up at the dewatering system.
The dewatering system separates large trash and debris as well as sand from the water. Specially designed sediment removal equipment is being used to separate the dredged sediment particles from the slurry in order to produce dry sediment material and a clear, clean effluent that can be discharged back into the resacas. This is being accomplished in a very limited land footprint with minimum environmental and noise disturbance.
Discoveries of large trash or debris can delay progress because those items clog the pipe system leading to the dewatering system. In those cases, operations will have to temporarily stop while the crew removes the obstruction. Tires, furniture and carpet are already among the larger items that have been found.
