Advanced Enviro-Septic® Manuals and Approvals
Advanced Enviro-Septic is now approved in New Hampshire.
Enviro-Septic® Manuals and Approvals
- New Hampshire grants New Innovative/Alternative Technology Approval allowing a 30" vertical separation distance to seasonal high water table, bedrock or other impermeable surface. Enviro-Septic® design plans already approved with a 36" separation distance may be amended by the designer to reflect a 30" separation distance without submitting a new application to NHDES (if system size and location are not changed). Designers must incorporate a note reflecting this revised ITA Approval on all Enviro-Septic plans. Click here for more information (PDF file)
Bypass Venting alternative to Differential Venting
(Differential venting is required for systems utilizing a pump to gain elevation to the field)
Flow Equalizers
When do we require flow equalizers and what type is allowed?
A flow equalizer is always required on distribution box outlets whenever the flow is being divided. If only one outlet of a distribution box is being used, a flow equalizer is not required. Our preference is that the Polylok
® flow Equalizer
® be used, which is claimed to maintain equal flow even when the distribution box shifts over time and becomes out-of-level. However, our manual does allow the use of other equivalent devices. When pumping to a distribution box the same rule would apply; if only one distribution box outlet is being used, no flow equalizer is required.
