- Service shall not be commenced or continued for a new customer or customers without written application on a form to be provided by the utility signed by every person aged 18 years or older living at the place who is not a “dependent” of one of the others as defined by state and federal income tax provisions. In the case of a husband and wife, both shall sign the written application.
- The application form shall include the certification under penalty of perjury by all persons signing the application that no one who is not a dependent of one of the others as defined above shall reside at the place other than the persons signing the application.
- The application form shall state that all persons signing the service contract agree to be “jointly and severally liable for payment for all services rendered at the place” (the phrase “jointly and severally liable” is a legal term of art that makes each signatory responsible for the entire debt, not just what they may deem to be their “share” of the debt).
(Ord. 657 – Mar. 12 Supp.)
111.06 BILLING FOR ELECTRIC SERVICE.
- Bills Payable. Bills for combined service accounts shall be due and payable at the office of the Clerk by the tenth (10th) day of each month.
