Sewer Use Ordinance

Overview


No person shall cause or permit a discharge into the sanitary sewers that would cause a violation of the Village's WPDES sewer discharge permit and any modifications thereof.
New connections to the village's sanitary sewer system will be allowed only if there is available capacity in all of the downstream wastewater collection and treatment facilities.


Control of Industrial Wastes


If any waters or wastes are discharged, or proposed to be discharged to the public sewers, which contain substances or possess the characteristics enumerated in Section 12.08.020 C of the Village Code, and which in the judgment of the approving authority, have a deleterious effect upon the wastewater collection or treatment facilities, processes, equipment or receiving waters, or which otherwise create a hazard to life, health, or constitute a public nuisance, the approving authority may:
1. Reject the wastes;
2. Require pretreatment to an acceptable condition for discharge to the public sewers;
3. Require control over the quantities and rates of discharge;
4. Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer charges under the provisions of Section 12.08.020 D of the Village Code.

Review and acceptance of the approving authority shall be obtained prior to the discharge into the public sewers of any waters or wastes having:
1. A BOD greater than 200 milligrams per liter;
2. A suspended solids concentration greater than 250 milligrams per liter;
3. A chlorine requirement greater than 25 milligrams per liter;
4. A phosphorus concentration greater than 6 milligram per liter;
5. A nitrogen concentration greater than 20 milligrams per liter.

Sampling Manholes


Each customer or facility that discharges industrial or other than residential wastes to a public sewer shall if required by the approving authority, construct and maintain one or more sampling or control manholes or access points to facilitate observation, measurement and sampling of the wastes, including domestic sewage. Similarly, each customer or facility desiring to make a new connection to a public sewer for the purpose of discharging industrial or other than residential wastes shall at the time of construction provide and thereafter maintain one or more control manholes or access points to facilitate observation, measurement and sampling of the wastes including domestic sewage. Control manholes or access facilities shall be located and constructed in a manner acceptable to the approving authority. If measuring and/or sampling devices are to be permanently installed they shall be of a type acceptable to the approving authority. Control manholes, access facilities and related equipment shall be installed by the business or facility owner discharging the waste, at the owner’s expense, and shall be maintained by the owner, so as to be in safe condition, accessible and in proper operating con­dition at all times. Plans for installation of the control manholes or access facilities and related equipment shall be approved by the approving authority prior to the beginning of construction.

Waste Sampling


Industrial wastes discharged into the public sewers shall be subject to periodic inspection and a determination of character and concentration of said wastes. The determinations shall be made as often as may be deemed necessary by the approving authority. Samples shall be collected in such a manner as to be representative of the composition of the wastes. The sampling must be accomplished by use of flow proportional sampling equipment acceptable to the approving authority.
Installation, operation and maintenance of the sampling facilities shall be the responsibility of the person discharging the waste and shall be subject to the approval of the approving authority. Access to sampling locations shall be granted to the approving authority or its duly authorized representatives at all times. Every care shall be exercised in the collection of samples to insure their preservation in a state comparable to that at the time the sample was taken.

Analyses


Laboratory procedures used in the examination of industrial wastes shall be those set forth in "Standard Methods." However, alternate methods for certain analysis of industrial wastes may be used subject to mutual agreement between the approving authority and the person. Determination of the character and concentration of the industrial wastes shall be made by the person discharging them, or his agent, as designated and required by the approving authority. The Village may also make its own analysis of wastes and those determinations shall be binding as a basis for charges.

Pretreatment


Where required, in the opinion of the approving authority, to modify or eliminate wastes that are harmful to the structures, processes or operation of the wastewater collection or treatment plant the person shall provide at his expense such preliminary treatment or processing facilities as may be determined required to render his wastes acceptable for admission to public sewers.
