[Amended at time of adoption of Code (see Ch. 1, General
Provisions, Art. I)]
The City Council hereby finds that the requirement for the issuance
of state loans and the acceptance of such loans by the City under
the Wisconsin Clean Water Fund Program and Environmental Improvement
Fund, §§ 281.57 and 281.59, Wis. Stats., respectively,
and other state and federal financial aid, and the regulations of
the Wisconsin Department of Natural Resources as set forth in Chapters
NR 110, 162, and NR 210, Wisconsin Administrative Code, for the construction
and operation of waste treatment works to improve the quality of effluent
discharges from the City establish:
A. The necessity of adopting a user charge system that would be proportionate
to all classes of users and produce the revenue required to sustain
the sewage collection and waste treatment system;
B. The necessity of enacting regulations that control the use and inflow
into wastewater treatment works.
[Amended at time of adoption of Code (see Ch. 1, General
Provisions, Art. I)]

of financial assistance to improve the quality of effluent discharges
from the wastewater treatment works. It is further intended to provide
for administration and enforcement of this article and to provide
penalties for its violations. It is further intended to implement
provisions of agreements by and among the City, the Town of Lake Mills
and the former Rock Lake Sanitary District No. 1 relating to the dissolution
of the sanitary district and the transfer of assets and liabilities
thereof to the City.
It is not intended by this article to repeal, abrogate, annul,
impair or interfere with any existing easements, covenants, deed restrictions,
agreements, rules, regulations, ordinances or permits previously adopted
or issued pursuant to law. However, wherever this article imposes
greater restrictions, the provisions of this article shall govern.
In their interpretation and application, the provisions of this
article shall be held to be minimum requirements and shall be liberally
construed in favor of the City and shall not be deemed a limitation
