What Creates Water Pressure?

Published in Water Systems 1 min read

Water pressure is primarily created by two forces: gravity and pumps.

Here's a breakdown:

  • Gravity Pressure: This type of pressure occurs due to the weight of water above a certain point. The higher the water reservoir (like a tank or a hilltop source) is located above an outlet, the greater the pressure at that outlet. Think of it like stacking books – the books at the bottom experience more pressure due to the weight of the books above.

  • Pumped (Boost) Pressure: When gravity alone isn't sufficient, pumps are used to increase water pressure. These pumps draw water from a source and then force it out at a higher pressure. This is common in buildings where the water source isn't elevated enough to provide adequate pressure, or in situations needing a substantial increase in pressure for industrial processes.

In summary, water pressure relies on either the force of gravity acting on a height of water, or the mechanical force of a pump increasing the pressure of the water.
