relative to location of conventional septic systems relative to the seasonal high water table.

This bill updates regulations for sewage and waste disposal systems in New Hampshire to allow stone and pipe systems to be installed up to 24 inches above the seasonal high water table, provided there is at least 6 inches of sand beneath them. It requires property owners subdividing land or building new systems to submit detailed plans that include specific data on burial sites and soil conditions for department review. The law also streamlines the approval process for larger lots of five acres or more by reducing the need for extensive soil testing unless hydric soils are present, while still mandating final inspections before any system goes into operation. These changes aim to provide clearer guidelines for construction while maintaining safety standards for wastewater management.
