Rapid Response Minimizes Pipe Failure at Encina Wastewater Treatment Plant

March 2011, Vol. 66 No. 3
Rapid response was critical to contain the spill and keep the line in operation by utilizing bypass pumping.

“The increased capacity of the 60-inch pipe was a bonus for us, knowing that the pipe will be large enough to carry the ultimate projected flows,” Smith added.

The Houston pipe manufacturing facility received the order Monday morning, Oct. 11 and was able to ship the pipe that same day. “Although we don’t make pipe to stock, we do carry a large inventory of product to be delivered in the next several weeks. In this case, we could borrow the product from an ongoing job, and remake the pipe for the other ongoing project and deliver both on time,” stated Paggioli.

“For this delivery, we acquired team drivers to minimize the transit time between Houston and the West Coast,” commented Rob Epstein, Hobas assistant commercial manger. The pipe arrived via truck at the treatment plant in Carlsbad two days later on Oct. 13.

The next morning, J.R. Filanc Construction Co. of Escondido, CA, commenced repairs. The entire 320-foot reach was installed by open trench construction with the pipe connecting to the influent structure on the treatment plant site.

The repair was completed by Oct. 19, only 12 days after the failure had occurred thanks to the teamwork of the Carlsbad Utilities Department, Brown and Caldwell design engineers, the J.R. Filanc Construction crew and the rapid pipe delivery by HOBAS Pipe USA.
