Drainage Field Size

What size of soaXaway Drainage Field Kit do you require?

To calculate the size of Drainage field require you should have completed your Ground Porosity Test which will provide a (Vp) value. The Vp value multiplied by Number of persons (P) multiplied by a factor (0.25 for Septic Tanks, 0.2 for Treatment Plants) will give you the Area (A) required in Sq Mtrs. Laid in a 600mm wide Trench Divide Sq Mtr by 0.6, This will give you the required pipe length.


Septic Tanks: A = Vp x P x 0.25

Sewage Treatment Plants: A = Vp x P x 0.2

Calculation Charts

Using the formula, we have created charts to make Drainage Field sizing easier. Simply select VP from column and Tank size from rows to give area required and pipe required.
