How the Septic Tank Size Calculator Works:
The calculator works by first determining the number of people expected to reside in the property based on the number of bedrooms. It uses a standard occupancy rate, where one bedroom is assumed to have three occupants, two bedrooms have four occupants, three bedrooms have 5 occupants, and so on.
Once the number of occupants is determined, the calculator applies a simple formula to calculate the minimum size of the septic tank required. The formula used is:
Minimum Size of Septic Tank = (Number of people x 150 L) + 2000 LitersThis formula is based on the assumption that each person generates approximately 150 liters of waste per day, and a minimum capacity of 2000 liters is required to comply with building regulations and environmental agency general binding rules.
How the Results Were Arrived At:
The results provided by the septic tank size calculator are derived from the standard guidelines and regulations set by building authorities and environmental agencies. These guidelines take into account factors such as the number of occupants, average daily waste generation per person, and the minimum capacity required for proper waste treatment and disposal.
The formula used in the calculator is a simplified version of the more complex calculations used by professionals in the field, but it provides a reasonable estimate for residential properties with up to 10 bedrooms.
