[Added 12-17-2025 by Ord. No. 2025-9]
a.
Nothing herein shall be deemed to apply to the replacement or repair of an existing septic system.
b.
Preservation Area. Development proposals involving new or increased demand for septic system capacity in the Preservation Area shall be regulated in accordance with NJDEP Highlands Area Rules (N.J.A.C. 7:38).
c.
Planning Area. All development proposing new or increased demand for septic system capacity in the Planning Area shall be regulated in accordance with this subsection. The following are gross septic density requirements and shall not modify any minimum lot size requirements contained in the Union Township Zoning Ordinance. Every development shall provide for a minimum acreage for each dwelling unit (or equivalent) as noted below.
1.
Septic System Density Allowances. Septic system density (gross acres per septic system) shall not exceed the following allowances, for each Highlands Zone:
(a)
Existing Community Zone: 10 acres/septic system.
(b)
Conservation Zone: 10 acres/septic system.
(c)
Protection Zone: 27 acres/septic system.
2.
These allowances indicate the minimum acreage required per septic system, where that system is designed for a one-family household generating a maximum flow of 300 gallons of wastewater per day. The resulting acreage shall be applied as the minimum average acreage necessary to support every 300 gallons of daily wastewater flow generated by any proposed use where the unit/square footage figures below shall be applied as 300 gallon-per-day equivalents.

(e)
Specific non-residential uses by facility type: In lieu of Subsection c3(c) or (d) above, 300 gallon-per-day equivalents may be computed based on the average sewage volumes provided in N.J.A.C. 7:9A-7.4.
