The image above represents specific storage.

To compute for specific storage, five essential parameters are needed and these parameters are **Density of Water (ρ _{w}), Acceleration due to gravity (g), Compressibility of the Aquifer (α), Porosity (n) **and

**Compressibility of Water (β).**

The formula for calculating specific storage:

S_{s} = ρ_{w}g(α + nβ)

Where:

S_{s} = Specific Storage

ρ_{w} = Density of Water

g = Acceleration due to Gravity

α = Compressibility of the Aquifer

n = Porosity

β = Compressibility of Water

Let’s solve an example;

Find the specific storage when the density of water is 22, the acceleration due to gravity is 9.8, the comepressibility of the aquifer is 15, the porosity is 10 and the compressibility of water is 22.

This implies that;

ρ_{w} = Density of Water = 22

g = Acceleration due to Gravity = 9.8

α = Compressibility of the Aquifer = 15

n = Porosity = 10

β = Compressibility of Water = 22

S_{s} = ρ_{w}g(α + nβ)

S_{s} = (22)(9.8)(15 + 10(22))

S_{s} = 215.60 (15 + 220)

S_{s} = 215.60 (235)

S_{s} = 50666.0

Therefore, the **specific storage** is **50666.0.**
