In addition to the powers granted by R.S. 33:3811, the Calcasieu Parish Police Jury may create waterworks subdistricts within the boundaries of existing or future waterworks districts. These subdistricts shall be governed by the same board of commissioners that govern the waterworks district in which the subdistrict is located. The formation of these subdistricts shall not impair any obligations that may have been incurred by the waterworks district during the period of its existence.
