Designs for Residential and Commercial Septic Tank Installation are Very Different

Commercial septic tank installation is very different to residential installation in that the volume of wastewater used per person per day depends on the type of facility, how many visitors it has, how long they stay, and what they do. Sizing for a commercial tank and drain field is more difficult than it is for homes. The design for residential systems begins with a simple calculation of the number of occupants and the average volume of daily wastewater.

For instance, thousands of people may visit a gas station at a turnpike in one day, many of whom use the toilets. This can make a huge difference to wastewater volume, even if the length of a typical visit is fairly short.

The EPA Wastewater Manual provides a series of range tables about commercial wastewater production (per employee or visitor) in various types of facilities. It also covers other sources of potential factors that may influence the wastewater volume – for example, the number of parking spaces.

When designing commercial septic tank installation, great care should be taken when predicting wastewater volume so as not to include factors that may yield an unrealistic high flow, resulting in high capital costs. Likewise, underestimation should also be avoided because the mistake will become quickly evident when the system overloads and needs expensive modification.
