The Oceanside Water Pollution Control Plant is an immense project requiring 135,000 cubicyards of concrete. The plant is spread out over 12 areas of Pacific Ocean front, making multiple concrete pours necessary for nearly every working day. To achieve the goals of the project's general contractor of getting concrete to each pour location with a minimum of setup time and completing each pour quickly, a pumping subcontractor with long-boom equipment was brought in. Then the general contractor set up its own concrete crew rather than subbing out the work.

Booms span rough terrain and other structures to reach below-grade pours or discharge directly into wall forms. As soon as each pour is over, the operator reverses the pump, pulling concrete out of the boom and into the hopper. Without any further cleanout, he folds back the boom and moves to the next scheduled pour location. Setup is simply a matter of spotting the pump, placing wood crane pads for the outriggers, and leveling the unit. For wall pours, specifications require a bedding layer of mortar at the base of the pour to minimize honeycombing at the cold joint. Assistant project manager Don Hudson said pumping speeds concrete placing and also reduces the amount of cleanup time needed at the end of the pour.
