Any municipality which has combined its waterworks and sewerage system under the provisions of this article, or pursuant to provisions of any other law, may hereafter construct extensions, additions, betterments and improvements to either the waterworks system or the sewerage system of said combined waterworks and sewerage system, or both, and may finance the acquisition, construction, establishment and equipment of any such waterworks or sewerage system, or both, or the construction of extensions, additions, betterments and improvements to either the waterworks system or the sewerage system of such combined waterworks and sewerage system, or both, by the issuance of revenue bonds under the provisions of this article.
