Bailey Tanks and Pipes

After rigorous digital simulations, Bailey Tanks took it a step further with real-world load testing of our Chunky Charlie underground tanks. Partnering with Burrett & Associates, we buried our 2,000L, 3,000L and 5,000L tanks to see how they would perform under site conditions.

To monitor structural response during backfilling, three 50mm PVC pipes were inserted into the top face of each tank. These pipes extended above the final ground level and allowed measurement of vertical deflection during and after installation.

We also pushed the tanks beyond standard operating conditions, simulating worst-case backfill scenarios, measuring the deflections after adding 290mm of backfill in the second stage of testing and another 370mm in the final stage.

The results? Deflection measurements stayed well within safe limits. These results were particularly encouraging as they closely mirrored the estimates predicted in our earlier FEA simulations, confirming the accuracy of the digital models.

This hands-on validation reinforced the reliability and durability of the Chunky Charlie design, ensuring it meets the demands of underground installation.

Ever wondered what goes into designing a tank that can withstand the pressures of underground installation? In this case study, we take you behind the scenes with a deep dive into the Finite Element Analysis (FEA) of our Chunky Charlie underground water tanks.

The purpose of this case study is to document and analyse the process and outcomes of the FEA testing, carried out during the early stages of design. It covers the methodology, background, materials selection, simulations, results, conclusions, and implications that lead to our final product design. The testing particularly focused on top-loading deflection, stress points and hydrostatic uplift scenarios.

FEA testing allowed us to make smart material and design choices, to craft a tank built for durability and performance. Click the link below to read our case study on FEA testing:
