A. 
For each lot, parcel of land, building, or premises having a connection with the sanitary sewage system and being served with water solely by the water utility, the quantity of wastewater for billing purposes shall be measured by the water utility water meter used upon the premises. A user will be allowed a credit for the portion of water furnished that is not discharged into the sanitary sewage system if all of the following conditions are met:
(1) 
The Village Board determines that the discharge of water outside of the Village sanitary sewage system will not cause any hazard to the public health, safety, or welfare;
(2) 
The user, at the user's own expense, causes the necessary plumbing work, including the installation of couplings, to be done by a licensed plumber so that a separate meter can be set.
(3) 
The user monthly pays the current charge for checking and inspection of the second meter. The credit for nondischarged water shall be applied to the user's account two times a year (December 31 and June 30) or when the Village deems necessary.
(4) 
The Village shall retain authority to remove, change, or inspect the meter at its discretion.
(5) 
Credit for nondischarged water shall not be applicable to commercial, industrial or public authorities, but shall apply solely to residential users.
B. 
Requests for usage adjustments or a second meter or service must be made in writing to the Village.
Devices for measuring the volume of waste discharged may be required by the Village if this volume cannot otherwise be determined from the metered water-consumption records. Metering devices for determining the volume of waste shall be installed, owned, and maintained by the discharger. A maintenance schedule must be accepted by the Village. Following approval and installation, such meters may not be removed without the consent of the Village.
Wastes discharged into the public sewers shall be subject to periodic inspection and a determination of character and concentration of said wastes. The sampling may be accomplished either manually or by the use of mechanical equipment acceptable to the Village. The use of flow-proportional composite sampling is preferred.
The Village may reassign sewer users into appropriate sewer service charge classes if wastewater sampling program and other related information indicate a change of classes is necessary.
No user shall receive free service or pay a sewer user charge less than the user's proportional share of operation, maintenance, and replacement (O,M&R) costs.
All users within the sewer service area of the Village shall be treated equally as to sewer use charges, except that users outside the Village boundaries shall pay a surcharge equal to 125% of the total sewer service charge less the sewer user charge.
