Current through Register Vol. 50, No. 9, September 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.
C. [Formerly paragraph 13:011-3] Effective
October 20, 2000, this rule applies to new individual sewerage system
installations, upgrades and/or modifications to existing systems required as a
result of an investigation by the Office of Public Health (OPH) into an
allegation that a violation of Part XIII of the Louisiana sanitary code has
occurred or is occurring, and has the potential for causing harm or creating a
nuisance to the general public (R.S.
40:1154). Such individual sewerage systems
with a capacity up to and including 1,500 gpd, that produce treated effluent,
and which, by design, do not significantly reduce the amount of off-site
effluent, shall be followed by an effluent reduction system constructed as
described in Chapter 7 Subchapter B,
§731 of this Part.
D. [Formerly paragraph 13:011-4] The state
health officer may consider for approval, on an individual basis, proposals for
developments that are of a unique nature, such as a development over water, or
irregular configuration, where individual sewage disposal is proposed, where
the development, by its very nature (e.g., where commonly or jointly owned
property is involved), is clearly not addressed by the current considerations
of this Code.
