said permit or issue a municipal infraction at any time
when such work is not being done in accordance with
the provisions of this chapter or the approved plans and
permit; and if such permit is revoked, it will be
unlawful for any person to proceed further with said
work without approval of the inspector.
(3) Right to inspect. The inspector or authorized rep-
resentative shall have access to any building or upon any
premises, at any reasonable time, when it is necessary to

believe that there exists a condition which makes such
building or premises unsafe or insanitary.
(4) Destroying posted notices. It shall be unlawful for any
person to willfully mutilate, deface, remove or destroy
any certificate or notice placed by the inspector in any
building in regard to the plumbing work in said building
until authorized to do so by the inspector.
(5) Notice of final inspection. It shall be the duty of the
person doing the work authorized by the permit to
notify the inspector, orally or in writing, that said
work is ready for inspection. It shall be the
responsibility of the permittee to ensure that access is
provided such that an inspection can be made. Upon
the satisfactory completion and final test of the plumb-
ing system a notice of final inspection, with the
signature of the plumbing inspector thereon, will be
posted in a suitable place in the building and a record
of such final inspection retained in the inspection
division.

placed than to the middle of the pipe prior to
inspection. Following inspection and approval, the rigid
pipe installation may be backfilled with approved
materials. Following review of the flexible pipe

ASTM D-2239 with joints made with ribbed insert fittings
secured by stainless steel clamps. All discharge line piping
where fittings are not visible or where there is doubt on the
part of the inspector of proper installation, shall be tested
for leakage by applying a 30 psi air pressure test for a
period of not less than one minute. Any loss of pressure
during the test will be cause for rejecting the installed pipe
and requiring repair or replacement of defective parts.
(B) Depth of Burial. The discharge line shall be buried to a
depth of at least 5 feet below the final surface grade. Where
that depth of cover cannot be maintained, cold weather
protection in the same manner as specified for water service
lines in Sec. 21.501(29)(B) , Ames Municipal Code, or by
another approved method, shall be required.
(C) Check Valve. A check valve shall be provided in the
discharge line, whether the discharge line flows by gravity or
is pumped. The check valve may be installed in either a
vertical or horizontal position. This check valve shall be in
addition to any check valve built into the sump pump.
C 30 9-17-92
(D) Electrical Service. For a sump pump to be operational, the
sump pump shall have a 20-amp circuit and 15-amp outlet.
The wire shall be 12-2 w.g. The sump pump shall have a
separate circuit. Where the fuse box lacks sufficient
capacity or where other electrical deficiencies will not
permit routine hookup of electrical service to the sump pump,
the homeowner will be so informed. In such cases, additional
costs could be incurred by the homeowner to correct the
deficiencies.
(E) Connection. The discharge line shall be connected to a public
storm sewer, collector line, or storm sewer intake if such
exists adjacent to the property. The connection to the storm
sewer or collector line shall be made by machine tapping and a
manufactured fitting, or by an alternate method of an
approved tap and saddle on a concrete storm sewer pipe. A
tap shall be used on all 6 inch collector lines. A sewer
tapping machine shall be used for all tile lines.
1 - The correct saddle to use to connect to a 6"-15" tile
line is a Gemco sewer saddle (B.F.O.) .
2 - The correct saddle for a collector line of 6" plastic is
a PVC saddle tee secured with stainless steel clamps.
3 - To connect a storm line to a concrete pipe, use a saddle
made with a cast iron hub. The pipe will extend from
the hub to the face of the pipe. Cement mortar and
oakum will be used for a water and root-proof connection
to the storm sewer.
(F) No Connection Available. If a storm sewer or collector line
does not exist in the roadway fronting the property, the
discharge line shall be terminated at the back of curb. In
the event the storm sewer/collector line is on the opposite
side of the pavement, the discharge line shall be extended
across the street. Back-of-curb discharges shall be directed
downward to the pavement by use of an elbow or other
approved arrangement. The City of Ames shall be
responsible for the connection to the storm sewer/collector
line for those services properly terminated at back-of-curb.
(G) Sump Pump. Delivery of the foundation water to an approved
point of disposal shall be made using an approved pump
system. The sump pump shall be able to deliver 17 gpm
against 17 feet of head.
(H) Gravity Discharge. In some instances, foundation water may
be discharged to an open waterway or other natural
drainageway by gravity when approved by the administrative
authority. Under no circumstances will a gravity line be
approved without backwater control.
C 31 9-17-92
(I) Alternative Uses. With prior approval, the property owner
may install such piping and valves necessary to allow the
foundation water to be used for lawn or garden watering or
other such use. However, said diversion facilities shall be
in addition to the permanent connection to the storm
sewer/collector line.
(40) Add a new chapter 15 to read as follows:
Chapter 15. Storm Sewer Service
15.1 The storm sewer service line or designed private storm sewer
shall be made of cast iron, reinforced concrete pipe (RCP),
vitrified clay pipe (VCP), SDR 35 polyvinyl chloride pipe
(PVC), PVC truss pipe, or PVC meeting ASTM F949. PVC
pipe shall conform to ASTM D-3034. PVC resin shall meet
cell class 12454B per ASTM D 1784.
15.2 Installation requirements. Installation shall be completed in
accordance with the standard specifications governing pipe
installations as established by the Public Works Department.
a. RCP, VCP and cast iron shall be installed according to
methods specified in ASTM C-12.
b. SDR 35 PVC shall be installed according to ASTM
D-2321. Embedment material shall meet ASTM C-33
(Crushed) Gradation 67.
15.3 Storm sewer service lines may be connected to the city storm
sewer system at intakes or manholes or directly into the city
storm sewer pipe. Tapping storm sewer service lines into city
storm sewers will be by using approved methods. The
connection from the storm sewer service line to the city storm
sewer will be made by a clamping saddle or a fitting with a
sealant that will be waterproof and rootproof.. The entire
connection shall remain uncovered for inspection and approval
before backfill. A collar will be installed at the main so
that the service line will not protrude into the main. If a
storm sewer service line is over half the size of the city
storm sewer it will require a manhole at the junction. The
manhole shall meet City of Ames Standard Specifications for
storm sewer construction. Taps will be installed on the top
half of the city storm sewer. Clean outs shall be installed
on storm sewer service lines at intervals not to exceed 80
feet of developed length and at locations where the line
changes direction more than 45 degrees. If a storm sewer
service line is installed with more than 25 percent grade, it
will be stepped down with the use of fittings.
15.4 Private storm sewer mains can be connected to the City storm
sewer system at intakes or manholes. Connecting into the city
storm sewer line with a private storm sewer main requires
installation of a manhole or intake at the junction. The
C 32 9-17-92
manhole or intake shall meet City of Ames Standard
Specifications for storm sewer construction. Manholes or
intakes on the private storm sewer line will be installed at
intervals not to exceed 300 feet and at all alignment and size
changes.
The Municipal Engineer shall review and approve all private
storm sewer systems designs prior to the issuance of a permit
to connect the private storm sewer system to the city storm
sewer.
15.5 Permits and applicable fees are required for any storm sewer
service lines or private storm sewer systems installed on
private property.
15.6 Inspection fees for installations utilizing VCP, RCP or cast
iron will be as currently established by City ordinance.
Inspection fees for installations using SDR-35 PVC will be as
from time to time adopted by city council for full time
inspection while the pipe and embedment materials are being
placed. Inspection fees for the embedment operation may be
waived provided a registered Engineer licensed to do business
in Iowa will certify that the pipe embedment has been
completed in accordance with the ASTM D-2321 Standards.
DIVISION VI. ADDITIONAL REQUIREMENTS
Sec. 21.601. PROCEDURE FOR ABATEMENT OF
PROHIBITED SEWER CONNECTIONS AND
DRAINAGE ARRANGEMENTS.

being allowed to enter the sanitary sewer system contrary to
Ordinance No. 1011 enacted December 19, 1961 and other ordinanc-
es of the city to the public detriment from resulting sewer back
ups and overloading of the sewage treatment plant, any connection
or arrangement found to exist whereby surface, subsoil or footing
drainage water is discharged or diverted into the sanitary sewer
system is deemed to be, and hereby declared as, a public nui-
sance.
(2) Whenever such connection or arrangement is found to exist in
violation of the ordinances of this city, whereby surface water
runoff, subsoil or footing drainage is discharged or diverted into
the sanitary sewer system, the city council may, after notice to
the owner or person in possession and control of the premises and
opportunity for a hearing, cause such to be abated by ordering a
connection to a public drainage system, storm sewer system,
natural watercourse or such other arrangement as the council shall
find necessary, adequate or appropriate, given the particulars and
circumstances of each case.
(3) If the person or persons so ordered fail to comply with the coun-
cil's order within the time prescribed when the order is made, the
C 33 9-17-92
council may cause the ordered work to be done, an accounting of
the cost of such work made and reported, and by resolution of the
council certify to the county auditor for collection in the same
manner as property taxes.
