What is an Engineered Septic System?

An engineered septic system is used in situations where a standard system cannot be installed. These systems are much more expensive and difficult to maintain and install. Unlike a regular septic system, an engineered septic system requires a plan, blueprints and approval before it can be put in place. The basic limiting factors that would require this type of tank would be an issue with the soil or rocks beneath the ground and local health ordinances providing restrictions on placement of tanks. The health department may require an engineered tank in areas where soil or ground quality is not ideal. This type of system would most likely be used in areas with a high population density such as a city or populous suburb.
