Current through Register Vol. 50, No. 6, June 20, 2024
A. Connections to Community Sewerage Systems.
				Where an established community sewerage system (either public or private) is
				available, and there is ample water supply, all plumbing fixtures within any
				structure shall be connected to such community sewerage system. Determination
				by the state health officer of the availability of a community sewerage system
				shall take into consideration, among other aspects, the separation (both
				horizontal and vertical) of the structure in question and the sewer main or
				lateral, political or geographic or legally created boundaries, and the
				available capacity of the sewer system.
B. [Formerly paragraph 13:011-2] Community
				Sewerage System Required. Community sewerage systems shall be provided for all
				new subdivisions and developments where lots are sold or leased. The
				developer/owner shall be responsible for the provision of adequate sewage
				treatment and disposal. The use of individual sewerage systems in lieu of a
				community sewerage system may be authorized and will be considered under the
				following circumstances.
1. In subdivisions
				comprised of less than 125 lots, when the developer submits a comprehensive
				drainage plan as well as a proposal for restrictive covenants which detail
				requirements for perpetual maintenance of drainage. This requirement shall
				apply for all new subdivisions and developments.
2. When the total anticipated design flow to
				the sewerage system does not exceed 1,500 gpd, and where no food service is
				involved as per §1301. A 2
3. On
				large lots, where an area of one acre or more is involved, having a minimum
				frontage of 125 feet.
4. The
				installation would be located on a lot, plot or site which has a minimum area
				of 22,500 square feet, and a minimum frontage of 125 feet.
5. For subdivisions when each and all lots
				have a minimum area of at least 22,500 square feet and a minimum frontage of
				125 feet, except that the 125 foot frontage requirement may be waived for up to
				15 percent of the total number of lots in the development if:
a. minimum frontage on each lot in question
				is not less than 60 feet, and;
b.
				the width of each lot in question is at least 125 feet.
6. For parishes in which the parish governing
				authority has enacted and enforces a formal sewage permitting system (requiring
				approval of individual sewage disposal systems by the state health officer
				prior to issuance of any parish permits) and when the lots or sites in question
				meet any of the following criteria:
a. minimum
				area of 22,500 square feet and a minimum frontage of 80 feet;
b. minimum area of 16,000 square feet and a
				minimum frontage of 80 feet where an approved individual mechanical plant is to
				be utilized;
c. minimum area of
				12,000 square feet and a minimum frontage of 60 feet where an approved
				individual mechanical plant is utilized and is followed by 50 feet of modified
				absorption field (see Chapter 7 Subchapter B, §733 A)
7. Where lots of "record" (i.e., lots created
				by formal subdivision prior to July 28, 1967) are combined (in accord with the
				definition of a subdivision) to create a new, larger, single lot, and no
				re-subdivision of the property is involved. On July 20, 2002 and thereafter, in
				no case shall the newly created lots have less than 50 feet of frontage or be
				less than 5,000 square feet in area.
8. For single lots or sites, regardless of
				size, remaining in substantially developed previously established subdivisions,
				when, in the opinion of the state health officer, a hazard to the public health
				will not result.
9. For single lots
				or sites, regardless of size, when the installation of an individual sewerage
				system is proposed in order to renovate or replace a pre-existing sewerage
				system. Such installation may be allowed when, in the opinion of the state
				health officer, a public health hazard or nuisance will not result. This
				provision shall apply to the renovation or replacement of pre-existing systems
				only and shall not be utilized to circumvent other requirements, particularly
				those relative to minimum lot size for new residences and subdivision
				development, of this code.
