[Ord. No. 45-1999, § 400.1, 2-1-2000]
No unauthorized person shall uncover, make any connections with
or opening into, use, alter, or disturb any public sewer or appurtenance
thereof without first obtaining a written permit from the City or
its authorized representative. All work related to the installation
of building sewers and the connection to the public sewer shall be
performed by persons qualified in this class of work and acceptable
to the City. The work shall be completed in compliance with all municipal
ordinances and state laws and regulations, with inspection by the
City for compliance. Failure to comply with inspection provisions
may result in excavating the installation for inspection.
[Ord. No. 45-1999, § 400.2, 2-1-2000]
(a)
Permit classes; application; fee. There shall be two classes of building
sewer permits: (i) for residential and commercial service, and (ii)
for service to establishments producing industrial wastes. In either
case, the owner or his agent shall make application on a special form
furnished by the City. This permit application shall be supplemented
by any plans, specifications, or other information considered pertinent
in the judgment of the City. A fee for a connection and inspection
permit for a sewer entrance to the City sewer shall be paid to the
City prior to connection to the City sewer. The amount of the fee
shall be as from time to time established by the City council.
(b)
Deposit for costs of review. In the case of multiple building units
or connections, connections involving sewer extensions, or industrial
discharge or pretreatment applications, the City may require a monetary
deposit sufficient to cover the cost of review of the application,
including any expert advice deemed necessary by the City. The amount
of deposit shall be estimated by the City and upon payment by the
applicant kept in an account. Upon completion of the review process,
the unused portion, if any, will be refunded. If the initial deposit
is not sufficient to pay for the costs incurred by the City, a second
deposit shall be made and handled in the same manner as the first.
[Ord. No. 45-1999, § 400.3, 2-1-2000]
A separate and independent sewer shall be provided for every building; except, where one building stands at the rear of another on an interior lot and no private sewer is available or can be constructed to the rear building through an adjoining alley, courtyard, or driveway, the building sewer from the front building may be extended to the rear building and the whole considered as one building sewer except for the purposes of section 62-35, and if approved by the City.
[Ord. No. 45-1999, § 400.4, 2-1-2000]

for inspection.
[Ord. No. 45-1999, § 400.14, 2-1-2000]
When any building sewer is to serve a school, hospital, or similar
institution, or is to serve a complex of industrial or commercial
buildings, or, in the opinion of the City, will receive sewage or
industrial wastes of such rate, volume, or character that frequent
maintenance of the building sewer is anticipated, then such building
sewer shall be connected to the public sewer through a manhole. The
City shall determine if and where this type of connection to the public
sewer is required. Connections to existing manholes shall be made
as directed by the City. If required, a new manhole shall be installed
in the public sewer pursuant to divisions 4 and 7 of this article
and the building sewer connection made thereto as directed by the
City.
