In what scenarios may an alternative OSSF design be considered?

An alternative On-Site Sewage Facility (OSSF) design is considered primarily when conventional systems are not feasible due to limitations in space or soil conditions. Certain geographical areas may have specific soil types or topographic challenges that render traditional sewage systems ineffective. For example, rocky soils may hinder proper drainage, while small lot sizes may not provide enough area for a conventional system to be installed and function properly. In such cases, alternative designs are explored to ensure effective sewage management and compliance with environmental regulations. These alternatives may include aerobic treatment units, mound systems, or other innovative technologies that can accommodate challenging site conditions while ensuring proper treatment and disposal of wastewater.
