Current through Register Vol. 50, No. 6, June 20, 2024
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.
