139 MILLION PROJECT

RELIABLE EQUIPMENT



The Challenge

Overcome the water shortage and everlasting drought.

The solution

Using the Triac Drive to weld Geomembrane material.

THE STORY

Located in Southern California, Assembly Supplies has helped the region to overcome the water shortage and everlasting drought. Working with a local Civil Engineering company we provided several of the welding tools necessary to fabricate the exposed geomembrane liner system of the Olivenhain Dam. Developed by the San Diego County Water Authority (SONJA) Emergency Storage Plan, The $139 million dollar project set out to build 8318 ft high roller compacted concrete (RCC) dam with the capacity to store more than 24,000 acre-feet of water. Once completed, it would be the tallest darn of its type in North America.

 

What part did we play in this? Assembly Supplies sells the entire line of Leister hot air welding tools, including those used in Civil Engineering. What was needed for this job though was something that could be used to weld up the side of a 318 ft tall vertical face. It was decided that the all-purpose Triac Drive would work best because of its unique design and size. The welders were suspended high up alongside the concrete dam where the geomembrane material was overlapped and draped hundreds of feet. Slowly working from the top down, they welded while continuously lowering themselves down, the 318 ft face, making sure to material and weld smooth and straight with the Triac Drive.
