No multi-unit commercial building or incubator-type building shall be constructed with only one service line and one curb stop. An
INCUBATOR-TYPE BUILDING is defined as a commercial or industrial structure which is built with the intention of dividing the usage among a number of tenants. Each unit within a multi-unit commercial building or incubator-type building shall be served with a separate meter and service line with a curb stop on each service. The separate meter and service line shall be located outside of the building near the supply line in a location where the meter can be easily read. A common header main shall run for the entire length of the building on the outside of the structure with individual service lines branching from the common header main to each separate unit; provided, however, that, a single meter is allowed to serve a multi-unit commercial building or incubator-type building where the building is in single ownership or in unified control so that the owner of the building or the managing agent of the building is responsible for paying the unified water bill, and the property owner agrees to place a covenant on the title of the property running to the benefit of the village whereby, upon the sale of the property to more than one individual, firm or corporation, or upon the partition of the property into more than one parcel, separately needed water services in accordance with the provisions of this chapter will be installed.
