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

The required setback distance of 10 feet from a pretreatment unit to constructed wetland cells or holding tanks for driveways is established to ensure proper separation for effective treatment and to minimize potential contamination of the treated area. This distance is crucial because it helps protect the integrity of the wetland cells, allowing them to function optimally without interference from runoff, odors, or potential blockage from vehicles or construction activities.

Maintaining a 10-foot gap also provides an adequate buffer to prevent any direct physical impact on the wetland system caused by heavy equipment or traffic associated with the driveway, which can lead to soil compaction and degradation of the treatment capabilities of the wetland. This regulation positively impacts environmental safety and public health, supporting the sustainable management of wastewater systems.
