(a) Uniform Requirements. This Chapter sets forth uniform requirements for discharging waters and wastes into the public wastewater facilities of the Village of Edgar. This Chapter enables the Village of Edgar to protect public health in conformity with administrative provisions, water quality requirements, and other discharge criteria required or authorized by local, state and federal law.
(b) Objectives. The objectives of this Chapter are to:
(1) Regulate the construction and use of public and private sewers and drains, and their disposal into the public sewerage system.
(2) Provide for annexations and connection to the public sewerage system.
(3) Provide a means of determining wastewater volumes, constituents, and characteristics, and to issue permits to certain users.
(4) Set limitations or restrictions on materials or characteristics of waste or wastewaters discharged to the wastewater facilities to prevent the introduction of pollutants into the wastewater treatment facilities that will interfere with the normal adequate treatment in the wastewater facilities, will pass through the system into the receiving waters, or contaminate the resulting municipal sludge.
(5) Recover from users of the wastewater treatment on an equitable basis, the share of the wastewater facilities cost attributable to such users, and to provide funds for the operation and maintenance, debt retirement and replacement of the wastewater facilities.

Quantitative determination of ammonia nitrogen shall be made in accordance with procedures set forth in the most recent edition of Standard Methods.
(2) Approving Authority. The Village Board of the Village of Edgar, or its duly authorized deputy, agent or representative, such as the wastewater treatment plant operator(s) or Village Engineer.
(3) Average Daily Rate. The total pounds of a constituent discharged to a sanitary sewer over a "sampling day" and shall be expressed in pounds per day. This rate shall be calculated by utilizing the "daily average concentration" and "total daily flow" for a given day.
(4) Average Hourly Rate. The total pounds of a constituent discharged to a sanitary sewer over a "sampling day," divided by twenty-four (24) hours and expressed in pounds per hour.
(5) Biochemical Oxygen Demand (BOD). The quality of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedure in five (5) days at twenty degrees Celsius (20°C), expressed in milligrams per liter or pounds.
(6) Building Drain. That part of the lowest horizontal piping of a drainage system which receives the discharge from the soil, waste, and other drainage pipes inside the walls of the building and conveys it to the building sewer, beginning five (5) feet outside the inner face of the building wall. The property owner shall own and be responsible to maintain the building drain sewer.
(7) Building Sewer. The extension from the building drain beginning at the immediate outside foundation wall to its connection with the sanitary sewer or other place of disposal.
(8) Chemical Oxygen Demand (COD). The measure of the oxygen consuming capacity of inorganic and organic matter present in water or wastewater. It is expressed as the amount of oxygen consumed from a chemical oxidant in a specific test. It does not differentiate between stable and unstable organic matter and thus does not necessarily correlate with biochemical oxygen demand.
