SEPTIC TANK SIZING
HOW BIG SHOULD YOUR SEPTIC TANK BE?
Your septic tank should have two compartments and be sized according to the estimated volume of wastewater generated daily. Below are guidelines to help you go above and beyond local requirements to ensure you aren't polluting.
Dimensions vary according to size and shape. Separating grey water and diverting this to the second chamber of the septic tank or treating this entirely separately greatly reduces your tank size requirements and improves efficiency.

HOW BIG SHOULD YOUR DRAIN FIELD BE?
Check your soil study (uso de suelo) for the permeability on your property. Check the date of the study and assume lower permeability rates in rainy season.
Your drain field consists of a perforated pipe that goes through a trench filled with gravel and should be sized according to the percolation rate of the soil on your property and the estimated volume of wastewater generated daily. This area must be clear of trees and cannot be used as a driveway. Below are guidelines to help ensure you aren't polluting.
If you do not have enough area for a proper drain field, you will require a contained wastewater treatment plant followed by a drain field or holding tank that is connected to an irrigation system to redistribute treated water on your property.
