What is the Force on Pool Walls at 88 Feet Depth?

Click For Summary
SUMMARY

The force exerted on the walls of a pool at a depth of 88 feet is approximately 40 psi, based on the principle that water pressure increases by 1 bar (or about 14.7 psi) for every 10 meters (or 33 feet) of depth. This calculation confirms that the atmospheric pressure is not the primary concern at this depth; rather, it is the hydrostatic pressure from the water itself. Pool builders and installers typically utilize certified designs and carry insurance to ensure safety and compliance with industry standards.

PREREQUISITES
  • Understanding of hydrostatic pressure principles
  • Basic knowledge of SCUBA diving equipment
  • Familiarity with pool construction standards
  • Knowledge of pressure measurement units (psi, bar)
NEXT STEPS
  • Research hydrostatic pressure calculations for different depths
  • Learn about pool construction regulations and safety standards
  • Explore the impact of water pressure on various pool materials
  • Investigate insurance requirements for pool builders
USEFUL FOR

Pool builders, SCUBA diving equipment importers, engineers involved in pool design, and anyone interested in understanding the effects of water pressure on pool structures.

Hello,

We are an importer of SCUBA diving equipment and are building a pool. I see multiple formulas and opinions, I'm hoping for a KISS answer. Although I don't think Width or length has anything to do with my question, we are building a deep shaft pool that will be 25'Wx35'Lx88'D. What is the force on the walls at 88' please? is it atmospheric pressure, 1 bar per 10m/33' so about 40psi?

Yes, about 40 psi gauge

So do you think licensed pool builders/installers carry insurance and use certified designs? Why do you think that is?
