It looks like they updated the
acceptable systems two years ago. We still have the problem in greywater disposal. You have to have a septic tank and a minimum mound 60% the size of a full system for your lot. There is some variation based on whether your township is COG but you can't duck this expense if you're going with composting toilets.
8. Greywater Systems
The treatment of greywater requires the same methods of sewage disposal used in soil-based onlot
disposal systems. Occasionally, the applicant may wish to separate “blackwater” (domestic human
waste) from “greywater” (washwater etc.) in order to reduce the amount of absorption area needed.
The use of “blackwater” treatment systems such as composting, chemical, recycling and incinerating
toilets or privies (proposed in conjunction with water under pressure), must meet the following
conditions for the treatment of greywater:
A. An onlot system meeting Chapter 73 standards or other approved method of sewage disposal
must be installed to treat greywater flow from the structure. Septic tank installations must
consist of either a two-compartment rectangular tank or two rectangular tanks in series and
must be in conformance with Chapter 73, Section 73.31. Aerobic tanks used must be in
compliance with Chapter 73, Section 73.32.
B. Only the absorption area may be reduced by up to 40 percent as a compensation for the use of a
non-flush toilet alternative. No reduction of septic tank sizing is allowed.
C. If planning is required, general soil and site suitability must be conducted in accordance with
Chapter 71, Section 71.62.
D. When a blackwater treatment system is proposed for use in conjunction with a greywater
system in a subdivision, the provisions of Chapter 71, Section 71.63(f)(1) apply, i.e. the site
and soil suitability testing must be sufficient to document the availability of an area for a full
sized system.
E. An SEO that has successfully completed the appropriate DEP-sponsored continuing education
course that included this specific technology may independently review the design and issue
the permit for systems approved under this listing.
