No water or sewer service shall be provided to an applicant outside the corporate limits of the Village unless such applicant petitions for annexation to the Village, or if the applicant cannot annex to the Village pursuant to law, that such applicant must execute a pre-annexation agreement with the Village. In addition to any other provisions that may be contained in said pre-annexation agreement, the agreement must provide for the annexation of the property to the Village and must further provide, in those instances where the applicant desires water service to more than one single family residential unit, that the applicant demonstrate, to the satisfaction of the Village, that the proposed land use for which water is desired, is in conformity with the Regional Land Use Plans currently used and prepared by the Southwest Illinois Metropolitan Area Planning Commission.
