Tank manufacturers must keep records of who buys the tanks and where they are installed. Proprietary treatment processes must be approved by the National Sanitation Foundation, if such approval is available. Setback distances from private wells to drainfields will be reduced from current levels of 150 feet to 100 feet, unless the wells are pressure-cemented. In those cases, the distance can be reduced to 25 feet. Setback distances to property lines will also be reduced.
Homeowners can only install standard systems.
The use of low pressure dosing is prohibited in shrink-swell clay soils. Sand filters are established as the standard method of treatment prior to surface irrigation. The use of conventional on-site systems is restricted in floodways. Areas served by commercial spray irrigation systems must be enclosed by a fence to isolate the area from public contact. Gravel-less pipe can only be used in sandy soils, unless substituted in bed systems.
