inch in any dimension.
E. Ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers,

[Code 1991, § 18-84; Ord. No. 08-17, 6-10-2008]
A. No septic tank shall be constructed or maintained within the City
limits except with a permit granted by the City Manager, upon the
recommendation of the Health Officer. Such septic tank shall be installed
and maintained in conformity with specifications laid down by the
Health Officer according to the rules and regulations of the state
board of health. All septic tanks and other on-site sewage treatment
systems not requiring a Virginia Pollutant Discharge Elimination System
(VPDES) permit shall have pump-out accomplished at least once every
five years, in accordance with a schedule and regulations to be established
by the Director of Building and Development Services.
B. For new construction within a Chesapeake Bay Preservation Area, the
applicant shall provide a reserve sewage disposal site with a capacity
at least equal to that of the primary sewage disposal site. This reserve
sewage disposal site requirement shall not apply to any lot or parcel
recorded prior to October 1, 1989, if the lot or parcel is not sufficient
in capacity to accommodate a reserve sewage disposal site, as determined
by the local Health Department. Building shall be prohibited on the
area of all sewage disposal sites until the structure is served by
public sewer or an on-site sewage treatment system which operates
under a VPDES permit.
C. As an alternative to the 100% reserve sewage disposal site, owners
of such systems may use the option of installing an alternating drainfield
system provided the following conditions are met:
(1) Each of the two alternating drainfields in the system shall have,
at a minimum, an area not less than 50% of the area that would otherwise
be required if a single primary drainfield were constructed.
(2) An area equaling 50% of the area that would otherwise be required
for the primary drainfield site must be reserved for subsurface absorption
systems that utilize a flow diversion device, in order to provide
for future replacement or repair to meet the requirements for a sewage
disposal system. Expansion of the primary system will require an expansion
of this reserve area.
(3) The two alternating drainfields shall be connected by a diversion
valve, approved by the local Health Department, located in the pipe
between the septic (aerobic) tank and the distribution boxes. The
diversion valve shall be used to alternate the direction of effluent
flow to one drainfield or the other at a time. However, diversion
valves shall not be used for the following types of treatment systems:
(b)
Low-pressure distribution systems;
(c)
Repair situations when installation of a valve is not feasible;
and
(d)
Any other approved system for which the use of a valve would
adversely affect the design of the system, as determined by the local
Health Department.
(4) The diversion valve shall be a three-port, two-way valve of approved
materials (i.e., resistant to sewage and leakproof and designed so
that the effluent from the tank can be directed to flow into either
one of the two distribution boxes).
(5) There shall be a conduit from the top of the valve to the ground
surface with an appropriate cover to be level with or above the ground
surface.
(6) The valve shall not be located in driveways, recreational courts,
parking lots, or beneath sheds or other structures.
(7) In lieu of the aforementioned diversion valve, any device that can
be designed and constructed to conveniently direct the flow of effluent
from the tank into either one of the two distribution boxes may be
approved if plans are submitted to the local Health Department and
found to be satisfactory.
(8) The owner(s) shall alternate the drainfields every 12 months to permit
the yearly resting of half of the absorption system.
(9) The department of building and development services shall notify
the owner(s) annually of the requirement to switch the valve to the
opposite drainfield.
