A. A number of unique or special situations pose certain problems with respect to sewage disposal. These atypical cases are dealt with as follows.
1. Apartment
complexes, condominium complexes, hotels, motels, and other such complexes
shall be connected to a community sewerage system. A commercial treatment
facility shall be provided when no existing community sewerage system capable
of accepting the additional loading exists.
2. Single commercial structures, where less
than 1,500 gpd total flow is expected, and where the connection to a community
sewerage system to serve other loading sources as well is not required, may
utilize either an individual or commercial sewerage system, provided minimum
lot size requirements for the use of individual sewerage systems are met.
a. A commercial treatment facility shall be
installed for business establishments where the preparation of food and/or
drink is the primary business activity.
3. Treatment facilities for very small
trailer parks which contain five trailer spaces or less shall be sized at 400
gallons per day per trailer space.
4. Where a community sewerage system is not
available, structures occupied three days per week or less, and located in a
marsh/swamp area or over water, may utilize a limited use sewerage system
comprised of the following:
a. a septic tank
system consisting of three septic tanks in series (or an acceptable three-cell
or three-compartment tank) followed by an automatic chlorination device/system.
The first cell shall have a minimum liquid capacity of 500 gallons. The second
and third cells shall each have a minimum liquid capacity of 250 gallons. Each
of the three septic tanks (or each compartment of a three-cell tank) shall meet
all design, material and construction requirements for septic tanks as
described in
§715 of this Part. In addition to the
construction and material requirements in Chapter 7, Subchapter B, the
following restrictions/exceptions shall also apply:
i. metal tanks shall not be used;
ii. the tank(s) shall be demonstrated to be
water-tight;
iii. fiberglass tanks
shall be adequately coated to prevent deterioration by ultraviolet
light;
iv. where
multiple-compartment single tanks are used, only one access opening, of 6-inch
minimum diameter, per cell shall be required; and
v. tanks set below the normal high-water
level, shall be anchored or otherwise secured against movement;
vi. the chlorination system shall be provided
with a contact chamber of a minimum of 100 gallons, and shall be equipped with
an automatic cutoff to prevent flow from the third septic tank/chamber if the
chlorine supply is exhausted. Also, the effluent line from the chlorine contact
tank shall be protected against entrance of small animals or other pests by use
of a corrosion-resistant flap-type gate, screen, or other means approved by the
state health officer.
5. Vessels. Vessels which are permanently
moored shall be connected to an approved sewerage system.
