What is the required setback distance from a pretreatment unit to constructed wetland cells or holding tanks for cemeteries?

The required setback distance from a pretreatment unit to constructed wetland cells or holding tanks for cemeteries is 20 feet. This distance is crucial for several reasons. The primary concern is to ensure that there is adequate separation to prevent any potential contamination of the wetlands or holding tanks from the effluents produced by the pretreatment unit. Wetlands have delicate ecological functions, helping to filter and purify water, and maintaining a safe distance supports the health and integrity of these systems.

Moreover, maintaining a 20-foot setback enhances water quality by minimizing the risk of nutrient and pathogen transfer from the waste systems to the natural environment. Regulations are often designed with public health in mind, and this distance reflects a standard that balances operational efficiency with environmental protection. In areas such as cemeteries, where individuals may have heightened sensitivities regarding neighboring infrastructure, the larger setback distance helps to address community concerns about sanitation and environmental integrity.
