Regardless of whether a lot or parcel is within any municipality’s geographical limits, the owner or owners of any lot or parcel of land abutting on any street, alley, public way or easement on which a municipal sewer is now located or may hereafter be constructed and laid (whether constructed and laid under the provisions of this article or any other provisions of law) upon which lot or parcel of land any business or residence building is now located or may hereafter be erected, not connected with a public sewer, may be required and compelled by the municipality or by the board of health to connect any such building with such sewer. Notice so to connect shall be given by the municipality or by the board of health to the owner and to the lessee or occupant of such building. The owner or owners shall connect to the municipal sewer within thirty days after notice to connect has been sent by the municipality. Regardless of whether the owner or owners connect to such sewer, the municipality may bill the owner or owners of the lot or parcel and the owner or owners shall pay the municipality’s charge based on the actual water consumption on the lot or parcel. If the lot or parcel is not metered, the municipality’s charge shall be based on the municipality’s good faith estimate of the consumption on the lot or parcel.
